How to Use a Micropipette? | Learn from the Experts at Accumax
The foundation of science in any laboratory is precision. Any experiment’s success or failure can be determined by the precision of even a single microliter, whether you are analyzing protein samples, setting up a PCR reaction, or creating a culture medium. Therefore, becoming proficient with a micropipette is one of the most important skills that any student or lab professional can acquire.
In this guide, you will learn from the experts at Accumax how to use a micropipette correctly – understanding not only the technique but also the science behind every precise drop.
A micropipette is a precision tool used to measure and move extremely small liquid volumes, usually in the microliter (µL) range. It guarantees consistent results in experiments that require accuracy by enabling scientists to dispense precise amounts repeatedly with little or no error.
Micropipettes are made for ergonomic purposes, repeatable volume control, and ease of use, in contrast to conventional glass pipettes. From molecular biology to pharma research, wherever precision matters, they play an essential role in driving reliable results.
Accumax, a company well-known for its precisely designed lab solutions, has continuously improved the ergonomics and design of its micropipettes to provide dependability, comfort, and consistency in a variety of applications.
It’s crucial to realise that not all micropipettes are created equal before learning how to use one. Depending on the application and the required volume range, each type has a distinct function of its own.
Single Channel Micropipette
The single channel micropipette is the most widely used type in labs, and it is made to transfer liquid into individual tubes or wells. It works well for small-scale tasks like reagent dispensing, serial dilution, and sample preparation.
Multi-Channel Micropipette
Multi-channel micropipettes, usually in 8- or 12-channel formats, are used to fill or aspirate multiple wells at once for increased throughput and efficiency. They save time and effort and are a staple in PCR setups, 96-well plate experiments, and ELISA assays.
Fixed Volume Micropipette
These pipette are made to consistently dispense a single, predetermined volume. They are perfect for routine tasks where speed and consistency are crucial, like running the same volume of assays repeatedly.
Variable Volume Micropipette
The user can set and modify the desired volume within a specified range with a variable micropipette. It is ideal for labs that need accuracy and adaptability in a variety of experimental configurations.
Step-by-step Guide on How to Use a Micropipette
Even the most precise instrument depends on correct handling. Follow these steps to ensure accuracy every time you use a micropipette:
1. Set the Desired Volume (if using variable volume pipette)
Turn the dial to adjust the volume to the desired level.
Always stay within the micropipettes designated range (for eg. 10-100 (µL))
To prevent harming the internal mechanism, do not push the dial past its limit.
2. Attach the Pipette Tip
Firmly press the micropipette’s shaft into a compatible tip to attach.
Ensure the tip fits securely — a loose tip can cause air leakage and inaccurate measurements.
Accumax micropipette tips are designed for a snug, leak-free fit to enhance precision.
Press the plunger to the first stop while holding the pipette vertically.
Submerge the tip 2-3 mm below the liquid’s surface.
To draw up the liquid, slowly release the plunger while keeping your hands steady to prevent air bubbles.
Touch the pipette tip to the side of the receiving vessel.
Press the plunger smoothly to the first stop to dispense most of the liquid.
Then press the second stop to expel the remaining trace volume.
Withdraw the tip while keeping the plunger fully pressed, then release after removal to prevent re-aspiration.
Always discard the tip after a single use to prevent cross-contamination.
Use the ejector button to remove the tip safely without touching it.
6. Return to Neutral Position
Allow the plunger to rise back slowly — never snap it back, as it can create bubbles or wear out the spring mechanism.
By mastering these simple yet critical steps, you ensure consistency in every pipetting task.
Even experienced technicians can occasionally make errors that affect accuracy. Here are some pitfalls to watch out for:
Reusing tips: Increases risk of contamination and volume inconsistency.
Tilting during aspiration: Can introduce air bubbles or cause uneven aspiration.
Plunging too fast: Leads to foaming or inaccurate sample uptake.
Ignoring calibration: Over time, even high-quality pipettes can drift in accuracy and require recalibration.
Incorrect immersion depth: Dipping the tip too deep or too shallow affects the volume aspirated.
Avoiding these mistakes not only improves precision but also extends the life of your micropipette.
Expert Tips for Accurate Pipetting
Learning how to use a micropipette correctly is more than following steps — it’s about developing good habits. Here are a few professional tips from the experts at Accumax:
Pre-wet the tip: Aspirate and dispense the liquid a few times before final measurement to improve consistency.
Maintain a consistent rhythm: Uniform speed and pressure ensure reproducibility.
Keep the pipette vertical: Especially when aspirating small volumes.
Allow equilibration: Bring tips and liquids to the same temperature before pipetting to prevent volume variation.
Clean regularly: Wipe the shaft with ethanol and perform routine maintenance.
Why Proper Technique MattersÂ
An effective pipetting technique guarantees that your results are scientifically valid, minimises user fatigue, and lowers experimental error. Even a small error can affect reproducibility, data interpretation, and diagnostics.
Micropipettes are precision instruments that require respect, care, and attention in every use. They are more than just tools.Â
