Step-by-Step Guide to Achieving Consistent Pipetting Results

Pipetting is one of the important techniques in laboratories in many fields of study, ranging from molecular biology to chemistry, clinical research, and diagnostics. Every lab technician looks towards getting consistent pipetting results to obtain accurate data, reproducibility, and successful experiments. 

At times throughout the experiment, they experience significant pipette failure, which affects the experiment. Along with this, they could see themselves in the middle of nowhere, and may also need to restart the experiment. 

This could lead to affecting time management in the experiment procedures. It will also affect the quality of solutions involved in the experiment, as they will be exposed to the open air through the failed experiment. 

This blog has discussed the various steps that can be followed for consistent pipetting results which can prevent various concerns through experiments. Below are step-by-step instructions to assist you in maximizing your pipetting technique and achieving consistent results every time.

Steps to Achieve Consistent Pipetting Results

Choose the Correct Pipette and Tip

Starting with the experiment procedures, before this selecting the right pipette and tip is critical to precision and accuracy. A pipette used should be within the volume range of your liquid transfer. If you are eager to buy one, you can first compare micropipette price between brands and find the right one for you. 

Pipetting at the maximum or minimum limit of a pipette's capacity can be inexact. In addition, high-quality tips that are compatible with the pipette model guarantee a snug fit and do not leak or contain air pockets. If you work with volatile or sensitive samples, filtered tips may prevent contamination and preserve sample integrity.

Calibrate Your Pipette Periodically

Other than choosing the right pipette, calibration is important as it guarantees your pipette is dispensing the right volume. Following the pipette calibration guidelines is vital to ensure accuracy and compliance with laboratory regulations. 

It can be useful to look for the manufacturer's instructions and calibrate pipettes at least every 3-6 months, depending on how often they are used. Further, it may provide you with enhanced pipetting standards.

Regular testing for inconsistency can be achieved through gravimetric testing, where water is pipetted and weighed to check for accuracy. Pipettes must also be treated gently—dropping them or subjecting them to extreme temperatures can influence their calibration and result in inaccurate results.

Optimize Your Pipetting Technique

Using a uniform pipetting method may reduce errors and enhance accuracy. Among all the helpful methods, it is pre-wetting the tip by aspirating and dispensing the liquid once before actual pipetting. This prevents volume irregularities due to evaporation. 

Pipetting at a uniform angle is also essential; so hold the pipette vertically when aspirating and slightly angled around 10°-20° when dispensing. Aspirate with the tip 2-3 mm below the liquid level to prevent air bubbles. Besides, using continuous pressure when pressing the plunger and maintaining a rhythm constant for aspiration and dispensing provides consistent outcomes. 

A quick pause before dispensing is used to make the liquid steady, minimizing inaccuracy. When dealing with thicker liquids such as glycerol, reverse pipetting can also be used to facilitate thorough dispensing without being retained in the tip.

Avoid Common Pipetting Errors

Even old hands get pipetting wrong. Certain prevalent mistakes involve utilizing the incorrect pipette or tip, which could result in leakage and incorrect volumes. Failure to pre-wet the tip might also cause variation in volumes, particularly when aspirating volatile solutions. 

Excessive speed when pipetting might introduce air bubbles or foam into the liquid, which can eventually affect accuracy. Through this, improper pipetting, where the pipette is held off-centre while aspirating, may lead to differences in volumes. Additionally, temperature variations can impact precision, so it is important to allow cold or warm liquids to acclimate before pipetting.

Maintain and Store Your Pipette Properly

Proper maintenance extends the life of your pipette and can also play a major role in providing the required accuracy you crave. Investing in an automatic micropipette can also help improve precision and reduce manual errors. Regular cleaning with 70% ethanol and internal component checks can prevent contamination and mechanical failure. 

Storage is another important part of keeping your pipettes working. So pipette should be stored vertically on a pipette stand to avoid internal contamination and mechanical wear. When using high-throughput pipetting, switching between several pipettes can distribute the stress among multiple instruments. An easy method to test for leaks is to hold the pipette tip against the lab bench after aspirating and see whether liquid leaks out.

Standardize and Train Pipetting Techniques in Your Lab

Following best practices by all technicians of the lab ensures uniformity in experiments. Most laboratories rely on the best micropipette brand in India, Microlit, to provide high-quality and dependable pipetting equipment. 

Regular training sessions ensure that even seasoned scientists use proper pipetting techniques. Using Standard Operating Procedures (SOPs) ensures a standard approach, minimizing user variability. Furthermore, proficiency testing enables individuals to evaluate their pipetting skills and make improvements for improved reproducibility.

Conclusion

Consistent pipetting results are important for the required precision, reproducibility, and experiment success in laboratory settings. Utilizing a systematized protocol, lab personnel can avoid errors and optimize accuracy. Using a proper pipette and corresponding tips is the key to dependable liquid handling. Consistent calibration by the manufacturer is ensured to provide accurate measurements and rule out any disparity in the volumes measured.

Improving pipetting methods, including pre-wetting the tip, holding at a consistent angle, and applying steady plunger pressure, improves accuracy. Eliminating frequent errors like pipetting too rapidly, employing the wrong tips, and ignoring temperature equilibration increases precision. Maintaining pipettes properly and correctly storing them, such as frequent cleaning and leak testing, increases their lifespan and avoids mechanical breakdowns.

Apart from equipment maintenance, pipetting technique standardization throughout the lab via training sessions and following Standard Operating Procedures (SOPs) provides consistency in results. Spending money on quality pipettes and accessories, including those from well-known companies like Microlit, also aids in precise and reproducible pipetting.

By adopting these best practices, laboratories can provide consistent results, minimize experimental errors, and increase overall efficiency, resulting in more trustworthy scientific results.

Environmental Control in Liquid Handling: Tips for Accuracy

As liquid handling instruments are highly significant for the laboratory usage, it’s equally important to understand the environmental factors. Whether you are conducting basic research, performing clinical diagnostics, or engaging in high-throughput screening, accurate liquid handling is essential for reliability and accuracy of results. However, achieving accuracy is not solely dependent on the equipment used but also on the control of environmental factors. 

The Importance of Environmental Control

Environmental factors such as temperature, humidity, air pressure, and static electricity can influence the performance of liquid handling instruments like pipettes, dispensers, and automated liquid handling systems. These factors can alter the viscosity and density of liquids, affect the volume dispensed, and even cause evaporation or condensation, leading to inaccurate measurements. Understanding and controlling these environmental variables is crucial for minimizing errors and maintaining consistency in your experiments. 

Key Environmental Factors Affecting Liquid Handling

Temperature: Temperature fluctuations can affect liquid viscosity and volume. For instance, warmer temperatures decrease the viscosity of liquids, making them flow more freely, which can lead to dispensing a larger volume than intended. Conversely, colder temperatures increase viscosity, potentially reducing the volume measurement. It’s important to store reagents and samples at a consistent temperature and allow pipettes and liquids to equilibrate to room temperature before use. 

Humidity: Low humidity levels can lead to increased evaporation, particularly when working with small volumes. This can be especially problematic in applications like PCR or qPCR, where precise volumes are crucial. High humidity, on the other hand, can cause condensation inside pipette tips or tubes, also leading to inaccuracies. Maintaining a controlled humidity environment, ideally between 40-60%, can mitigate these issues.

Air Pressure: Changes in air pressure, particularly in high-altitude or climate-controlled environments, can affect the accuracy of air-displacement pipettes. This is because air pressure impacts the air cushion that forms between the liquid and the pipette tip, altering the dispensed volume. In such settings, positive-displacement pipettes or adjusting the calibration of air-displacement pipettes for specific conditions can enhance accuracy. 

Static Electricity: Static electricity is often an overlooked factor that can significantly impact liquid handling accuracy, especially with highly sensitive analytical techniques. Static charges can cause liquids to cling to pipette tips or cause droplets to jump, leading to volume discrepancies. Using anti-static lab gear and equipment and grounding metal instruments can help minimize these effects.

Tips for Ensuring Accuracy in Liquid Handling

Calibrate Equipment Regularly: Regular pipette calibration and other liquid handling devices is essential for maintaining accuracy. Calibration should be done under controlled environmental conditions to account for any potential deviations.

Use Compatible Tips and Reagents: Ensure that pipette tips and reagents are compatible with the equipment being used. Poor-quality tips or incompatible reagents can lead to inaccuracies due to leaks or improper fit.

Implement a Standard Operating Procedure (SOP): Develop and adhere to SOPs that include guidelines for environmental control, such as prewetting pipette tips, allowing liquids to equilibrate to room temperature, and standardizing the speed and angle of pipetting. 

Monitor Environmental Conditions: Invest in environmental monitoring tools to maintain and record temperature, humidity, and air pressure within the laboratory. This will help identify and rectify any potential sources of error related to environmental factors. 

Minimize Handling and Repeated Freeze-Thaw Cycles: Excessive handling and repeated freeze-thaw cycles can introduce variability in liquid samples. Minimize handling and use aliquots to avoid repeated exposure to environmental changes.

Conclusion

Environmental control is a critical yet often underestimated factor in achieving accurate liquid handling in laboratory settings. By understanding the effects of temperature, humidity, air pressure, and static electricity on liquid handling accuracy, and implementing strategies to control these variables, laboratories can enhance the reliability of their experimental results. Precision in liquid handling not only ensures the success of individual experiments but also contributes to the broader goal of scientific reproducibility and innovation.

Mistake: Failing to pre-wet the pipette tip before use can lead to inconsistent volumes due to evaporation or retention of liquid in the tip. 

Solution: Pre-wet the pipette tip by aspirating and dispensing the liquid several times before taking your final measurement. This helps to condition the tip and ensures consistent volume delivery.

3. Incorrect Pipetting Angle

Mistake: Holding the pipette at an incorrect angle while aspirating or liquid handling can cause air bubbles and inaccurate measurements.

Solution: Hold the pipette vertically (90 degrees) when aspirating liquids and at a 45-degree angle when dispensing. This minimizes air bubble formation and ensures accurate volume transfer. 

4. Plunging Too Quickly

Mistake: Rapidly depressing and releasing the plunger can introduce air bubbles into the sample, leading to inaccurate measurements.

Solution: Operate the plunger slowly and steadily. When aspirating, depress the plunger to the first stop, immerse the tip in the liquid, and release the plunger slowly. Similarly, dispense the liquid smoothly and consistently.

5. Immersing the Tip Too Deeply

Mistake: Immersing the pipette tip too deeply into the liquid can cause excess liquid to adhere to the outside of the tip, leading to volume errors.

Solution: Only immerse the tip 2-3 mm below the liquid surface when aspirating. For larger volumes, immerse slightly deeper, but avoid submerging the entire tip.

6. Using the Wrong Tip

Mistake: Using non-compatible or low-quality tips can cause inaccurate measurements and compromise the integrity of your pipette.

Solution: Always use high-quality, compatible tips recommended by the pipette manufacturer. Ensure the tips fit securely and are free from defects.
