How to Perform Solvent Distillation Using a Rotary Evaporator

Solvent distillation is a crucial process in chemical research and industrial applications. When it comes to separating solvents efficiently and safely, a rotary evaporator (or rotavap) is the go-to tool for researchers and professionals. This versatile piece of lab equipment allows for rapid evaporation at lower temperatures, preserving the integrity of sensitive substances.

If you’ve been wondering how exactly to perform solvent distillation using a rotary evaporator, here's an easy-to-follow guide to help you get started:

Step 1: Set Up the Rotary Evaporator

Begin by carefully setting up the rotary evaporator. Ensure that the condenser, collection flask, and bath are properly connected. Check that all seals are intact to prevent any leakage.

Step 2: Adjust Parameters

Set the temperature based on the solvent’s boiling point. The rotary evaporator allows temperatures to range from room temperature up to 180°C. Ensure that the rotation speed is also set to an appropriate level, typically between 0-120 rpm, depending on the solvent you are working with.

Step 3: Start the Evaporation Process

Activate the vacuum pump to create a low-pressure environment, helping to lower the boiling point of the solvent. Once the system is set up, turn on the rotary evaporator, and allow the flask to rotate. The rotating motion helps increase the evaporation surface area, making the process faster and more efficient.

Step 4: Monitor the Process

As the solvent evaporates, it condenses in the condenser and drips into the collection flask. Make sure to monitor the process and ensure that all the solvent has been properly collected.

Why Use a Rotary Evaporator for Solvent Distillation?

The rotary evaporator is ideal for this process because it reduces the need for high temperatures that could degrade sensitive compounds. It provides an efficient, safe, and precise way to evaporate solvents. Whether in academic research or industrial settings, the AKR-1010 Rotary Evaporator ensures high performance with features like:

Evaporation Capacity: 20L

Temperature Accuracy: ±1°C

Rotating Speed: 0-120 rpm

If you're looking for a rotary evaporator that can handle large volumes and offer precision, the AKR-1010 is an excellent choice.

Me: (watching rotavaps because when we run both rotavaps and the heat gun, sometimes the surge protector switches off, meaning the one rotavap may not hold vacuum, dumping whatever it’s holding into a filthy water bath)

Z: (hand behind a heat gun) It’s not even that hot

Me: I’m trying to make sure the rotavaps don’t shut off

Z: You have a student watching. You must show her you are fearless!

Me: Ok do you WANT your product dumped in the water? And your displays of fearlessness are why I forget to wear SAFETY GLASSES in a SYNTHESIS LAB

When you force the rotavap just as close to its limits as yourself, only to not feel as bad about your own issues since you know that something else around you is struggling just as much 😬

There’s a new whisky bar in TTDI! Located on the ground floor of Menara KEN, Director’s Cut (@directors_cut_ttdi) is run by the folks behind,er, The Whisky Bar, and boasts an impressive lineup of at least 700 whiskies, both official and independent bottlings. Besides whisky, food and beer, they also have a cocktail “culinary lab” with a list of drinks made in collaboration with a chemist, using a RoTAvAP R-300. Got to try the clarified ‘Crystal Espresso Martini’ which was actually pretty tasty, and a mulled wine riff called “His Excellency”. The bar only had its soft launch five days ago, and will have its official opening next week. #directorscutttdi #whiskybar #whiskybarkl #bar #cocktailbar #barreview #tipsyturvybarreview #mytipsyturvy #whisky #cocktails (at Menara ken ttdi) https://www.instagram.com/p/ClBTNEIJhhc/?igshid=NGJjMDIxMWI=

Understanding Different Types of Lab Equipment and Their Uses

A scientific lab has a wide range of specialized equipment and scientific apparatus. These equipment and apparatus are useful in chemical, pharmaceutical, biological food, cosmetic, and educational institutions’ labs.

Here are the different types of lab equipment and their uses:

Mixers, Shakers, and Stirrers

These apparatus are useful when mixing various chemical liquids and solids for different lab applications. Laboratory mixing apparatus come in different ranges: rotators and vortexes, 3D gyratory rockers, microplate shakers, linear shakers, orbital shakers, and magnetic stirrers. If you want to increase the capacity of any shaker, attach a clamp or any other suitable platform.

Centrifuge

A centrifuge is an equipment used to separate gases, fluids, and liquids with different densities. Centrifuges are mostly used in research laboratories to purify nucleic acids, proteins, viruses, organelles, and cells. In a hospital laboratory, a centrifuge is useful in separating various blood components such as plasma and serum.

Spectrophotometer

A spectrophotometer is equipment that helps determine the light intensity by measuring the number of photons absorbed as they pass through a specific solution. The equipment is also useful in determining the concentration of chemical substances by analyzing the amount of light intensity. Spectrophotometers are classified according to the wavelength range of their light sources.

There are two types of spectrophotometers:

UV-Visible spectrophotometer: This device uses visible light and ultraviolet rays under specific ranges under the electromagnetic spectrum.

IR spectrophotometer: This device uses visible light and infrared rays under specific ranges under the electromagnetic spectrum.

Thermostatic Bath

A thermostatic bath is useful in inactivating and incubating cell cultures, thawing frozen samples, processing chemical reactions, and warming bacterial media. It is an important piece of equipment in medical research, a special and standard lab that deals with industrial and scientific experiments. Modern thermostatic baths are equipped with microprocessors with a controller that allows temperature consistency and regulation.

There are two types of thermostatic baths:

Water baths

Oil baths

Ultrasonic Cleaner

An ultrasonic cleaner perfectly cleans laboratory equipment using high-frequency waves that pass through a cleaning liquid. The immersed part of lab equipment is cleaned by the agitated liquid solution, mainly a solvent or water. The ultrasonic cleaner works by causing cavitation to the solution. Cavitation is when sonic energy dislodges the contaminants from the equipment surfaces by attracting them to the solutions bubbles.

Incubators and Ovens

Incubators and ovens are mostly used in microbiology, biology, and clinical labs. Lab incubators are used to incubate media, samples, and reagents. A lab incubator provides a steady temperature when warming the samples or reagents. Other applications of incubators include biotech, pharmaceutical, clinical, bacteriology, and food and beverage testing.

Ovens are mostly used in laboratories for drying samples and glassware, annealing, product age acceleration, sterilization, evaporation, and polymerization.

Rotary Evaporator

Also known as rotavap, a rotary evaporator is an equipment that helps separate solvents from a given sample through evaporation. The process is usually done under low or reduced pressure. Lowering the pressure in the flask allows the solvent to boil at a low temperature. The solvent is mostly put in a round bottom flask to provide a larger surface area for faster evaporation. The most common solvents to be separated from a sample are hexane and ethyl acetate.

Polarimeter

A polarimeter is an equipment that measures the angle of rotation after an optically active material polarizes a light. Some chemicals are optically active and will polarize right, causing it to rotate either clockwise or anticlockwise. The intensity of such a light rotation is called the angle of rotation. The direction of rotation of the polarized light provides the properties of such substance and its concentration in a given sample.

Microtome

A microtome is cutting equipment used to produce very thin slices of samples under experiment. Microtomes are mostly used in microcopy, where samples are studied through electron radiation or observed through light. Most microtomes have diamond, glass, or steel blades. The blades vary according to the specimen to be used and the thickness of the slices required.

Conclusion

The apparatus and equipment mentioned above are useful when operating a laboratory, either industrial, research, or standard. At Biotechnical Services, Inc., we supply the latest high-quality equipment for your laboratory needs. Contact us today for any type or make of laboratory equipment.

In gen Chem lab I was so concerned that I broke two glasswares. Like how will I ever be a successful chemist if I’ve broken glasswares? Too accident prone. Too clumsy.

Here’s the stats of actual chemists:

Z: occasionally drops things. Gets frustrated when adapters get stuck and hits them hard enough with tweezers that they break

L: Occasionally fumbles flasks. Broke the rotavap as a rite of passage

S: drops things constantly. Broke the rotavap as a rite of passage. Then broke the other as well.

O: rarely fumbles flasks to the point of breaking them, but breaks test tubes like they’re disposable. Shattered a graduated cylinder. Has not broken the rotavap yet

Me: Occasionally breaks a flask. Manages to shatter test tubes instead of simply cracking them. Dropped a column and flattened the faucet. Broke the rotavap as a rite of passage.

I realized this is basically a movie run through rotavap and that's glorious.

some people just have their priorities right.

Wie Bars mit High-Tech-Geräten bessere Drinks machen

Da Cocktails in Top-Bars immer anspruchsvoller werden, ist mehr Arbeit erforderlich, um sie zu perfektionieren, und vieles davon geschieht jetzt hinter den Kulissen.Anstatt Obst in einen großen matel cup & mug zu gießen, der auf der Theke sitzt, verbringen Barkeeper Zeit in einer Küche oder einem Labor mit Vakuummaschinen, Tischstillständen, Industriefiltern und anderen Geräten.Eis ist nicht mehr schnellschmelzende Stücke, die aus einer Maschine ausgespuckt werden;es wird mittels Spezialgetriebe oder handgeschnitzt aus kristallklaren Blöcken durch professionelle Eisschneider in bestimmte Formen eingefroren.Ein leckeres Daiquiri kann Zutaten enthalten, die mit flüssigem Stickstoff eingefroren wurden, destilliert und geklärt wurden, alles, um Ihnen davor zu ersparen, MinzsBruchstücke in Ihrem Stroh zu bekommen.

Die Barkeeper verwenden immer noch frische und lokale Produkte, aber sie verfeinern jeden Aspekt der Cocktails, in denen sie verwendet werden, von der Temperatur über die Textur bis hin zum physischen Format.In dieser Diashow schauen wir uns einige der modernsten Geräte an, die in Bars auf der ganzen Welt eingesetzt werden.

Bei der Herstellung von Infusionen, Tinkturen, Bitter und Sirup setzen Barkeeper feste Zutaten in Flüssigkeiten ein und filtern sie dann aus.Herkömmliche Filtrationsmethoden umfassen den Einsatz von Sieben, Käsetüchern und Kaffeefiltern, aber zunehmend wenden sich Barkeeper zu anspruchsvolleren Techniken wie Buchner Trichter, und zumindest in diesem Fall, ein Weinfilter namens Mini-Jet.Das Gerät wird hergestellt, um Weißweine zu filtern, um Sediment zu entfernen und den wine tools zu polieren.Bei Canon in Seattle nutzt der Besitzer Jamie Boudreau den Mini-Jet, um Infusionen und Bitter zu filtern, die er an der Bar zum Verkauf anbietet und in den Getränken verwendet.Boudreau sagt, dass dieser Filter sowohl schneller als auch gründlicher als andere Filter ist, obwohl er nur die gröbsten verfügbaren Filterpads verwendet, um Sediment unter Beibehaltung des Geschmacks zu entfernen.Derzeit macht er drei verschiedene Bitter: Kirsche, Rhabarber und eine Rekonstruktion einer seit langem bestehenden Marke namens Boker's Bitters.Diese werden in einer Reihe von Getränken verwendet, einschließlich der Fighattan mit Feigengetränktem Bourbon und Boker's Bitters.

Die Artesian hat die beste bar set der Welt in 2013 für das zweite Jahr hintereinander aufgestellt, sie umarmt Opulenz in ihrem Cocktailprogramm, serviert Getränke wie eine, die mit einem schwebenden Duft-Ballon über dem Getränk kommt, und eine andere inspiriert von The Picture of Dorian Gray, die hinter einem Spiegel serviert wird, so dass Sie sich ansehen müssen, während Sie es trinken.Sogar das ice bucket in Artesian ist schick, speziell für die Bar mit einer Computer Numerical Control (CNC) Maschine wie diese geschnitzt.Sie verwenden diese Maschinen, um sowohl runde Eiskugeln aus Blöcken zu schnitzen, als auch um Logos auf große Eispucks zu prägen.Diese Pucks schwimmen auf den Getränken, die in ihren riesigen Cocktailgl��sern serviert werden.

Viele Bars und Restaurants wachsen jetzt ihre eigenen Kräuter, Früchte und Gemüse auf den Dachgärten, aber das ist wahrscheinlich eine Herausforderung während der Winter in Kanada.Der Besitzer der Victoria Bar Shawn Soole hat in Little Jumbo ein hydroponisches System installiert, um das ganze Jahr über Produkte anzubauen.Das Gerät ist mit dem Hauptwassersystem verbunden und hat Lichter an Zeitschaltern, so dass sie, sobald sie die richtige Sequenz herausgefunden haben, es einstellen und vergessen können (bis sie hineingreifen müssen und etwas für die Getränke pflücken müssen).Sie haben Minze angebaut, um Getränke wie die traditionelle Mint Julep und die Pontarlier Julep, plus Basilikum zu machen Gin-Basil Smashes, ein Cocktail, der ein beliebtes Sommergetränk in Deutschland ist.Während sie mit der Maschine immer noch die richtigen Wachstumszeiten wählen, sagt Soole, er wolle Verbena, Zitronenbaum und Thymian für zukünftige Cocktails anbauen.

In den letzten Jahren sind Cocktails auf dem Wasserhahn zu einem Trend geworden, weil Kunden ausgefallene, leckere Cocktails mit frischen, hochwertigen Zutaten wollen, aber sie wollen nicht auf 20-Minuten warten, bis Barkeeper in jedem Getränk Tropfen und Spritzen von 12-verschiedenen Dingen hinzufügen.Mit Cocktails können Barkeeper eine große Charge auf einmal machen und sie so schnell wie möglich ein Bier servieren.Und obwohl viele Bars jetzt ein oder zwei auf dem Wasserhahn anbieten, haben sie in Tavernita alle Arten von Bier und wine glass, plus zehn Cocktails auf dem Wasserhahn, und diese beinhalten Zutaten wie Paprika-getränkter RoggenWhisky, wine rack-Birnensirup und BBQ-Bitter.Der einfachste Weg, einen Cocktail am Wasserhahn zu servieren, ist, ein inertes Gas wie Stickstoff zu verwenden und es durch die Linie zu schieben, wie man es für Wein am Wasserhahn tun würde.Aber das funktioniert nur bei nicht-carbonatierten Getränken wie Netronis und Manhattans (und Sangria auch bei Tavernita).Hier gibt es auch Cocktails, die karboniert sind, wie einen Gin & Tonic mit hausgemachtem Tonikum und einen Cachaca-Drink mit Trauben-Soda.Die Fässer werden alle gekühlt und von ihrem „batchologen“ zubereitet, deren Aufgabe es ist, mit Präparaten sehr anspruchsvoll zu sein und die Inhaltsstoffe nicht nach Volumen, sondern nach Gewicht zu messen.Sie berechnen sogar die Verdünnung im Voraus und fügen dem Fass Wasser hinzu, je nachdem, ob das Getränk auf Eis serviert wird oder nicht.

Viele Barkeeper haben sich an Sous-vide Kochtechniken gewandt, um die Infusionen zu beschleunigen und ihre Konsistenz zwischen den Chargen zu verbessern.Die Methode umfasst vakuumdichtende Inhaltsstoffe (und Schnaps) in Plastikt��ten und deren Beheizung bei niedriger, kontrollierter Temperatur.Bei Pint Jigger, wahrscheinlich der fortschrittlichsten Cocktailbar Hawaii, heiratet der Besitzer Dave Newman die Sous-Vide-Küche mit einer anderen, neu bekannten Technik: Fass-Aging.Statt einen Cocktail zu mischen und ihn für einen Monat oder mehr in einem kleinen Fass zu altern, kauft Newman Jack Daniel s Holzschips zum Rauchen (aus Whisky-Fässern hergestellt) und legt sie stattdessen mit den Cocktailzutaten in Mason-Gläsern in das Sous-vide-Bad.Die Getränke nehmen holzige Aromen und eine seidigere Textur nach nur zwei oder drei Tagen im Sous-vide auf, anstatt die gleiche Anzahl von Monaten in einem Fass.Newman hat mit dieser Technik flattergealterte Cocktails gemacht, darunter Boulevardier, Martini, Dark N Stormy und Vieux Carre.

"Wahrscheinlich siebzig Prozent der Cocktails auf der Speisekarte haben etwas, das durch die Zentrifuge gegangen ist", sagt Dave Arnold von Booker && Dax.Die Zentrifuge wird mit einer erstaunlich großen Anzahl von Zutaten verwendet, und diese Zutaten werden durch die Zentrifuge, je nachdem, wie sie in Cocktails verwendet werden.Schließlich wird die Zentrifuge einfach verwendet, um Zutaten nach ihrem Gewicht zu trennen.In einigen Fällen kann dies als wirklich guter Filter funktionieren, wie wenn Arnold Mandel-Sirup-Orgeat macht oder das Sediment der Bitterstoffe filtert.Er verwendet auch die Zentrifuge bei der Klärung von Säften und bei der Trennung von "milchpwed" Spirituosen.Zur Klarstellung Säfte Arnold die Frucht oder die Zitrusfrüchte, fügt Enzyme hinzu, um sie weiter zu zerlegen (manchmal auch mit Weinfiniermitteln), dann spinnt er sie in der Zentrifuge, um die Flüssigkeiten von den Feststoffen zu trennen.Er sagt, das macht nicht nur schöne klare Säfte, sondern erhöht auch den Ertrag über nur mit einem Entsafter allein.Zum Waschen von Milch fügt er Milch zu Spirituosen hinzu und trennt dann die zerkleinerten Milchstückchen.Es klingt widerlich, aber Getränke wie klassische Milk Punches unterziehen diesen Prozess auch, nur nicht in einer Zentrifuge).Die milchgewaschenen Geister haben eine weiche Textur, und wenn sie in Cocktails geschüttelt werden, erzeugen sie einen schönen Schaumkopf.Die gereinigten Säfte werden in Rührgetränken (in der Regel werden alle Getränke mit Säften geschüttelt, aber diese brauchen sie nicht mehr) sowie in kohlensäurehaltigen Cocktails verwendet, wo sie besser die Fizz des Getränks behalten.

Ein Rotary Verdampfer ist eine Miniatur, die immer noch typisch für Chemiker ist, die einige Barkeeper in letzter Zeit verwendet haben.In den meisten Ländern ist es illegal, die Ausrüstung zu verwenden, um selbstgemachten Wodka zu produzieren, zum Beispiel (zum Teil weil die Regierung Steuern auf den Alkohol erheben will), aber in einigen Ländern nutzen Barkeeper es, um High-Level-Infusionen, Reduktionen und andere Flüssigkeiten zu schaffen.Sowohl in einem traditionellen Still als auch in einem Rotavap werden Mischungen durch Verdunstung durch unterschiedliche Siedepunkte (in der Regel trennen Alkohol von Wasser) getrennt, aber in einem Rotavap kann dies bei weit niedrigeren Temperaturen getan werden, um empfindlichere Aromen herauszuziehen und zu vermeiden, sie zu verbrennen.Als der führende molekulare Mixologe Tony Conigliaro von der Bar ohne Namen sagt in seinem Buch The Cocktail Lab,"Was ich an dem Rotavar liebe, ist, dass es eines der kompliziertesten Geräte des Labors ist, aber die daraus hergestellten Produkte sind unglaublich poetisch." Conigliaro betreibt dies immer noch, um Dinge wie Pferdradische Wodka, die in einer Bloody Mary verwendet wird, und eine Portweinreduktion, die in einem Getränk mit dunklem Rum und Grenadine verwendet wird.Es kann auch verwendet werden, um alkoholfreie Zutaten wie Orangenblütenwasser, das in einem Ramos Gin Fizz verwendet wird.

Ein Super-Kühler, oder das zirkulierende Bad, kühlt schnell die Zutaten ab, die in seine super-kalte Mischung aus Ethanol und Wasser getaucht werden.In Chicago's Progressive Aviary schwimmen sie etwa acht Minuten lang mit Wasser-Ballons im Bad.Das ist genug, um eine Schicht Wasser im Ballon einzufrieren.Dann knallen sie den Ballon, stechen ein kleines Loch in die Eiskugel, um das flüssige Wasser in der Mitte zu saugen, und ersetzen es durch einen Cocktail wie den Vieux Carre.Dann, um etwas extra schick zu machen, knacken die Trinker diesen Cocktail "in den Felsen" mit einer Schleuder am Tisch.) Staff hier auch tauchen hohe Collins-Gläser mit Wasser in das Bad, damit ein Ärmel aus Eis um die Innenseite erfrieren kann.Anschließend spülen sie den restlichen slush ab und werden mit einem eisgesäumten Glas, in dem sie kohlensäurehaltige Cocktails servieren, gelassen, da die Blasen so sprudelnd bleiben.Sehen Sie sich dieses coole Video des Eisprogramms an.Foto von Christian Seel

March 30, 2023

I was helping Mam April in preparing the reagents for Biochem lab this 10:30 when you arrived. You inmediately assited the student returning their borrowed appratus and said your good morning to us. I was busy in the activity of SHS and I did let you took over the dispensing area. We were both waiting and checking for each other for the lunch as Mam Danica and Mam Anj prepared a lunch for the WCC Committee. We decided to go at office to check if food is available already since we're both hungry. Unfortunately, food is jot yet there but pizza is there and we had to take a slice of pizza to ease our hunger. We came back in the lab after grabbing a slice of pizza. We kept on saying that we're both hungry. We waited for the food and had a convo that I forgot the topics we talked about.

Then, Mam Joan called in the office to ask forna favor to assist Mam Anj in picking-up the food they ordered at Rina's mom. They immediately staretd opening the food to grab lunch. We decided to just take part since there were still lab classes. When we return, we immediately grab lunch but I had to assist the sampinit and Sotto's group. When I returned, we started eating our lunch. I can see that you were enjoying the food and kept praising the food. You even mentioned that you did not take your dinner last night and you're super hungry which I called you out but kept shifting the topic. You even asked how is patient counselling is usually done sinfe Aye, Val and Kyle were part of a team which I explained. I asked how how were you paying for electric and water bills. You said that your elecctril.was reloadable and water is equally divided by number of occupants. You hate the idea of asking your roomate for their payment since you do want to carry the burden of paying for them. While I was preparing for OrgChem reagent, I sat in the chair and you sat beside me while having your avocado ice cream. I even teased you of putting the reagents to your ice cream but established the bad thought and idea of it. I went in the office for a meeting with Sir Jonyl about CRADLE. I PmEd how are you but got a 3 question mark response. I explained that I'm fed up with our meeting already since new task was added to us. You replied that you're also done for today due to the number of students and subject conducting experiments which you even said, "Papanget nila" After the meeting I saw you in the rotavap assisiting the students. I'm fed up with new tasks assigned to us and saw your notes in the telephone and had to contact the offices. I went in the office to grab ice cream. When I sat in my table, I received a call from Doc DG to explain the latest activity in our experiment. You were busy assiting the OrgChem and thesis studebts while I'm on my phone and had to be assited by Kyle and Aye since my ID got ice cream. When Zy was in the lab, he assisted you in the students returning their borrowed glaaswares. Meanwhile, I was checking for the reagents for tomorrow's lab. I brought the Inorg lab reagents and you immediately assisted me in preparing the reagents. I prepared for the Group 1 and 5 cations while you prepared for the 3M nitric acid and Doc Kevin came in the office to remind me of pH meter and thermometer he'll bringing with him tomorrow. When Bien came back in the lab, he can't stop talking and bragging his spectro experience in his class. You both instructed then to wash the glasswares. You also helped me in dispensing for Pcog class and you mentioned about your long vacation next week for the computation of your daily rate since you asked your mom if you're Dada can pay for your rate on Tuesday since you will be absent from work. You even shared that you'll charge triple of your rate

Val went in the office to ask me to choose between ice cream and sweet corn and I said ice cream and I decided the same for you as well. When I retuned from office, you gave the ice cream Val bought for us. After dispensing, we sat in the table and chatted before deciding to grab dinner at office later. When Rowel came in the lab to return the hot plate, he asked us if we can grab dinner since there were remaining foods. I suddenly opened up to Bien about my dilemma that I shared to him while you were away. The idea of just seeing you flexing you ss will be the end of me. I told him I'll be devastated and will cry for days or even weeks. He gave me practical advice. When Sotto's group is done, we went in the office. I even called you Princess since it took you time cause you were still fixing and preparing yourself. Bien and I went in the office first since window in dispensing is open and you offered that you'll check and lock it. We took dinner at the pantry with Mam Danica and Mam Nikki. You microwaved the dish but you did not sit beside me. We enjoyed our lunch and had a conversation about our siblings, the feeling of being a child. You shared a story about your mom and dad decided not to give you a sibling since your mom undergone oophorectomy. I asked for your parents age and they're 58 and 52 respectively. Your mom conceived you when she was 27-28 years old. Mam Danica also shared story about his sibling. You also shared that they enjoyed riding in motorcycle as their bonding and past time to explore and you supported them all the way. You even shared a funny story about waiting for them at home since no one is home and your house is locked casue they're away. You had to wait until they come home for you to enter the house. Mam Danica teased you about your dating status and your mum about it. I shared a part of my story about blnot doing any household chores at home which you called me again, "Princess" After checking the CDDD lab, you said your goodbye already and you said that you might sleep immediately since today is tiring.

P.S I might get used at you calling me "Princess"

Oh yeah, rotavaps generally don't come with the vacuum pump, so you'll want to look for that online too. Should be less expensive than the evaporator itself though.

Is it possible to get a rotavap for cheaper than $1000 and have it be any good at all
