Brief Introductions of Pipette Tips

Pipette tips are an indispensable accessory for pipettes. In some famous theories, the quality of the tip also is very important in the accuracy of pipetting, and its significance is no less than the pipette itself. Below is a brief introduction to pipette tips.

Brief Introductions of Pipette Tips:

Material of the pipette tip:

High-quality tips are generally made of natural polypropylene.

In addition, pipette tip material often with small amounts of additives. The more common additives are:

Color material. The common blue tips (1000ul) and yellow tips (200ul) on the market are with corresponding color-developing materials in polypropylene (as a user, you must hope that it is a high-quality color masterbatch, not low-quality) cost industrial pigments. )

Release agent. Mainly used to help the tip release quickly after molding. Due to the high production process requirements, often rare for pipette tips without additives are on the market, so our users can only choose pipette tips with fewer additives when choosing.

Classification of pipette tips:

1. Filtered pipette tip

There is a filter (usually white) on top of the filter. Such filter elements are typically made of polypropylene, similar to the filter structure of a cigarette.

Due to the existence of this filter element, the pipetted sample cannot enter the inside of the pipette, thus protecting the parts of the pipette from contamination and corrosion, and more importantly, it can also ensure that there will be no cross-contamination between samples.

Therefore,  filtered pipette tips are also an important tool for pipetting volatile and corrosive samples. Of course, the price of filter tips is relatively high compared to general tips, and the domestic market share is very low.

In addition, there are few domestic suction heads with filter elements, and their filtering effect is not satisfactory.

2. Sterile pipette tip

Hawach company provides the sterile pipette tip, which has all sizes, like 200μL, etc. And all of the sterile pipette tip with high-quality medical-grade polypropylene (PP) material;

The tips with high-temperature resistance, no deformation after high temperature, and high-pressure sterilization

3. Special tips.

Designed special tips are tips for special samples or special applications.

There are mainly the following categories:

The first category is gel tips (also known as dispensing tips): the tips of tips are either flat or very thin and are for electrophoresis experiments;

And the second category is the wide-mouth suction Tip: The diameter of the tip is larger than that of the ordinary tip, which is mainly for removing macromolecular solutions such as proteins;

Then the third type is the low-adsorption tip: the inner wall of these tips reduces the surface adsorption force, which removes viscous liquids;

The fourth type is the extension tip: mainly used to take liquids in containers such as volumetric flasks;

The fifth type is the outer piston tip: mainly used for special outer piston pipettes and pipettes on the continuous dispenser.

Features of pipette tip:

1. What are pipette tips used for:

First, the professionalism of the tips. Certain series of pipettes from certain brands can only use their own standard tips and cannot use other tips. For example, Rainin’s multichannel pipettes must use their own LTS tips;

The second is fit. The most common situation is that a pipette can use multiple tips, but the pipetting effect varies from tip to tip.

Third, should adjust the tip and pipette range. And the tip volume should be greater than or equal to the maximum pipette range. For example, a pipette with a maximum range of 20ul, 100ul and 200ul can use a 200ul tip;

Fourth, the characteristics of large-capacity pipette (5ml, 10ml, 20ml) tips. Large pipettes from the major pipette brands often require their standard tips, and replacements are difficult to find.

Therefore, if we need to buy tips, should tell the supplier which tip model we apply or at least the brand and capacity of the pipette we use.

2. Biological contamination

More and more users now require tips that are free of RNase, DNase, DNA, pyrogen, and ATP contamination.

And autoclaved tips are not completely guaranteed to be free of biological contamination.

Hawach company ensures there is no biological contamination, and gamma-ray treatments to produced.

There are also introduces about the function of disposable pipette tips, what is sterile filtered pipette tips, etc.

#Repeater pipette manual

AutoRep S is a manual repeater pipette with a volume range of 2 L-5 mL and features the high precision and accuracy of positive-displacement pipetting. Manual pipettors tend to be very durable and easily maintained, while electronic pipettors have the advantage of increased accuracy, reduced force, and a lower risk of repetitive stress injuries. A manual repeater pipette allows the user to repeat-dispense precise aliquots of any liquid, including viscous or volatile liquids. Next, choose manual versus electronic operation. No air cushion means more accurate pipetting of high-density samples. Pipette holder 2 for an electronic Eppendorf Multipette (Repeater) f.Carousel 2,wall mounting (w/o charging function). Samples that are viscous, radioactive, corrosive, or volatile tend to require a positive-displacement pipet, which has a disposable piston and direct piston–sample contact. Start by choosing a displacement method: Air-displacement pipets are often recommended for aqueous samples since there is always an air cushion (dead volume) between the sample and the piston. Pipets and pipettors are used to transfer or measure set volumes of liquid, ranging from 0.1 µL to 10 mL.

ceridwenfaerie replied to your photoset: The outline is done!! Now I just need to do a few...

Out of curiosity, what colors are you considering?

It’ll be the same colors as the actual pipette we use. So the body will be a slightly off white, the knob on the left side and some details will be grey and the buttons and part of the handle will be a dark blue. If you look up “Rainin Multichannel Pippette” on google image, the fourth image is closest to what I’m going for!
