Micropipette Pipette Selection

Choosing the right micropipette pipette is a key step for strong results in immunoprecipitation. You need to match your pipette to your sample and task. This helps you reach the highest accuracy and precision.

Volume Range

You should always match the pipette’s volume range to the amount you want to measure. Each pipette works best within a certain range. If you use a pipette that is too large for a small sample, you risk losing accuracy. For example, if you need to measure 20 microliters, pick a pipette with a range of 2–20 microliters, not one that goes up to 200 microliters. The smallest suitable pipette gives you the best control and helps you avoid mistakes.

Tip: Always choose the smallest pipette that can handle your sample volume. This simple step improves your results.

You can see the difference in accuracy in the table below:

Ergonomics

You will spend a lot of time using your micropipette. Comfort matters. Modern micropipettes have lightweight bodies and soft grips. These features help your hand stay relaxed. Adjustable plunger forces make it easier to press and release the pipette. These designs lower your risk of hand strain and help you avoid mistakes. When you feel comfortable, you can work longer and keep your accuracy high.

Note: Ergonomic pipettes do more than protect your hands. They also help you avoid errors that come from fatigue.

Calibration

You need to check your pipette’s calibration often. Regular calibration keeps your pipette accurate. Over time, pipettes can drift from their set values. This can lead to wrong measurements. You should follow a schedule for calibration and keep records of each check. Many labs send their pipettes for certification once or twice a year. You can also check calibration in your lab with simple tests.

Some pipettes use air displacement. Others use positive displacement. Air displacement pipettes work well for most water-based samples. Positive displacement pipettes are better for thick or sticky liquids. You should pick the right type for your sample to keep your results accurate.

Callout: Always check your pipette’s calibration before starting a new set of experiments. This habit helps you trust your results.

Pipette Tips

Low retention tips stop liquid from sticking to the inside of the tip. You get more of your sample back, which is important for small or expensive reagents. If you work with proteins or viscous liquids, low retention tips give you better accuracy. You also avoid bubbles, which can affect your results.

You should always choose the right pipette tips for your task. High quality pipette tips and low retention tips help you get the best results in immunoprecipitation.

Pipetting Technique

Consistent Angle and Depth

You need to keep your pipette vertical when you draw or dispense liquids. Holding the pipette at a steady angle helps you avoid sample carryover and keeps your measurements accurate. You should immerse the tip just below the surface of the liquid. If you dip the tip too deep, you risk drawing up extra fluid or causing contamination. If you keep the tip too shallow, you may pull in air and create bubbles.

• Hold the pipette straight up and down.
• Immerse the tip 2–3 millimeters below the liquid surface.
• Release the plunger slowly to draw up the sample.

Tip: Always check the angle and depth before you start pipetting. This habit helps you ensure accuracy and precision in every step.

Pre-Wetting and Bubble Avoidance

Pre-wetting the pipette tip helps you get consistent performance. You should aspirate and dispense the liquid once or twice before you measure your final volume. This step coats the inside of the tip and reduces errors from liquid sticking to the walls. Pre-wetting also helps you avoid bubbles, which can change your results.

If you pipette too fast, you may create bubbles or lose sample. Mixing at a fast speed can lead to a significant loss of antibodies, with a 32% reduction in yield compared to slow washing. Medium-speed washing causes a 4% loss of conjugated antibodies. You should move the plunger slowly and steadily. This technique helps you keep your results reliable and reproducible.

• Pre-wet the tip by aspirating and dispensing the liquid two times.
• Move the plunger slowly to avoid bubbles.
• Watch for bubbles in the tip and discard any sample with bubbles.

Note: You can choose the right pipette tips to help prevent bubbles and sample loss. High quality pipette tips and pipette specific tips give you better control.

Minimizing Hand Strain

You spend a lot of time using your micropipette pipette. You need to protect your hands to keep your technique strong. Hand strain can lead to errors and lower your performance. You should use ergonomic pipettes with soft grips and adjustable plungers. Take breaks during long pipetting sessions. Stretch your fingers and wrists to keep them relaxed.

• Use pipettes with comfortable grips.
• Adjust the plunger force to a level that feels easy.
• Take short breaks and stretch your hands.
