Micropipette Guide 2024: Types, Applications and More

Micropipettes or pipettes, are instruments used to measure liquid ranging between volumes of 1-10000 µl and transfer it from one sample container to another. This is a basic liquid-handling instrument for almost all scientific laboratories.

Types of Micropipettes

There is no 1 way to classify micropipettes. It can vary in a number of ways.

1. Number of Channels

Single Channel Micropipettes

A single-channel micropipette has only 1 channel to aspirate and dispense the liquid. It means you can handle only one sample at a time.

Multi-Channel Micropipettes

Multi-channel micropipettes can handle 8, 12 or 16 samples in one go. It can attach multiple tips at the same time and you can get the work done faster especially if working in high-throughput labs.

2. Volume Adjustment

Fixed Volume Micropipettes Here the volume a pipette can aspirate and dispense remains the same and you don’t have the option to adjust or choose between a range. They offer consistent and accurate results for repetitive pipetting.

Variable Volume Micropipettes

Variable volume pipettes give you the flexibility to choose the volume you want to pipette (within the given range). You need to set the volume manually on the dial. High-performance pipettes also come with a volume lock feature for enhanced safety and reliability.

3. Operating Mechanism

Mechanical Pipettes

These are the standard pipettes widely used in all laboratories. Mechanical micropipettes operate on a piston-driven system, where users manually set the desired volume using a dial and apply thumb pressure on the plunger to aspirate and dispense liquids.

Electronic Micropipettes

Electronic micropipettes are more expensive than mechanical ones because they have digital controls, programmability and eliminates the element of human error to a certain extent. It has an electronic display and is ideal for high-throughput labs where reproducibility is paramount.

Components of Micropipette

Plunger

The plunger is one of the main components of the micropipette. Use your thumb to press down on the plunger to aspirate and dispense the liquid.

Then, with a firmer push, sometimes called the “blow-out stop,” it ensures a thorough expulsion of any remaining liquid, guaranteeing accurate measurements—a two-step process of liquid control.

Ergonomics are a key point here since lab professionals will be pipetting repeatedly for long hours. A low-force mechanism which does not require excessive plunge force, will minimize the RSI.

Volume Adjustment Dial

By twisting the volume adjustment dial, you dictate the micropipette’s plunger movement, determining your experiment’s liquid dosage. In micropipettes with adjustable volumes, this feature offers precise measurement control, no matter how small or large the quantity is.

Tip Ejector

Keep your hands and micropipette clean by disposing of used tips promptly. Utilize the convenient tip ejector button to effortlessly remove micropipette tips, ensuring a fuss-free and contamination-free experiment environment.

Tip Cone The tip cone, also known as the shaft, is the crucial component of a micropipette where the disposable tip is inserted. Its primary function is to ensure a snug fit for the tip, ensuring precision in measurements and preventing air leakage. Its adaptable shape accommodates various sizes and styles of tips, allowing for versatile and secure usage without concerns of detachment or disruptions.

Calibration Screw Inside the micropipette lies a crucial component, the calibration screw. This is what makes accuracy possible. Twisting this tiny screw adjusts the liquid output, fine-tuning the micropipette’s performance. Regular checks and tweaks, as advised by the manufacturer, ensure precision in your measurements, keeping everything flowing smoothly.

Applications of Micropipettes in Laboratory

Micropipettes are used to measure any small amount of liquid samples for testing and research. They are crucial in lab settings like molecular biology and diagnostics, precisely transferring tiny liquid volumes, facilitating diverse experiments. Mastery of their principles is key to effective scientific research and analysis.

Some common applications include:

1. Molecular Biology 2. Biochemistry 3. Cell Culture 4. Microbiology 5. Analytical Chemistry 6. Clinical Diagnostics 7. Pharmaceutical Research

How does a Micropipette work?

Micropipettes operate on the principle of air displacement. They consist of a plunger connected to an internal piston, which moves to two distinct positions: Filling Position: When the plunger is depressed to the first stop, the internal piston displaces a volume of air equal to the desired volume shown on the volume indicator dial. This creates a vacuum, drawing the liquid into the tip. Dispensing Position: The second stop on the plunger is used solely for dispensing the contents of the tip without drawing in additional air.

How to use a micropipette?

1. Start with choosing the right micropipette and micropipette tips

Select the one that is best for your application. While pipettes are similar in the way they function, what sets them apart is the accuracy and precision of the measurement, ergonomics and general durability of the instrument.

Set the volume based on your requirement and ensure the tips match the volume of the pipettes.

2. Attach the micropipette tip to the micropipette

Don’t use excessive force here because good quality pipettes will be quick and seamless to attach to the tips and should provide a leak-proof seal.Immerse the pipette in the liquid at 90 degrees Be mindful of your posture and keep the position upright. Aspirate and dispense 2-3 times before actually measuring the liquid

3. Forward or Reverse Pipetting

First let’s talk about forward pipetting:To aspirate the liquid in the tip, press the plunger to the first stop. Immerse the pipette tip vertically in the liquid. Slowly release the plunger while the tip is immersed. The liquid will be aspirated into the pipette tip. To dispense the liquid, place the tip on the inner wall of the receiving vessel at a steep angle Slowly press the plunger to the first stop to dispense the liquid. To empty the tip completely, press the plunger to the second stop.

Now for reverse pipetting

The reverse technique is suitable for dispensing reagents/solutions that have high viscosity or a tendency to foam easily. It is also recommended for dispensing very small volumes.To aspirate the liquid in the tip, press the plunger to the second stop and immerse the pipette tip vertically in the liquid. Slowly release the plunger while the tip is immersed. The liquid will be aspirated into the pipette tip. To dispense the liquid, place the tip on the inner wall of the tube at a steep angle. Slowly press the plunger to the first stop. Finally, eject the tip and dispose it off

Calibration of Micropipettes

Calibration is conducted through gravimetric testing, which involves weighing the amount of pure water delivered in a single operation of the pipette. The obtained mass is divided by the density of water to determine its volume. Variable volume pipettes should undergo testing at three or more points across their designated range, typically at maximum volume, 50% of maximum volume, and the lower limit of their range.

Here’s a general guide on how to calibrate a micropipette:

1. Gather MaterialsMicropipette(s) to be calibrated Appropriate pipette tips Distilled water or a calibration solution Weighing balance with appropriate accuracy (usually in milligrams) Gloves and lab coat for safety

2. Prepare the Micropipette Ensure the micropipette is clean and free from any residue. Attach a fresh and compatible pipette tip to the micropipette.

3. Pre-Wet the Pipette Tip (Optional) For some micropipettes, pre-wetting the tip with the liquid being used can help ensure accuracy. Follow the manufacturer’s recommendations regarding pre-wetting.

4. Prepare the Calibration Solution Use distilled water or a calibration solution recommended by the micropipette manufacturer.

Ensure the calibration solution is at room temperature to minimize density variations.

5. Set the Micropipette to the Desired Volume Adjust the micropipette to the volume you want to calibrate (e.g., if calibrating a 10-100 μL micropipette, set it to 50 μL).

6. Dispense Liquid into a Weighing Boat or Container Dispense the liquid from the micropipette into a weighing boat or a container placed on a weighing balance.

Note down the initial weight (W1) of the liquid dispensed.

7. Weigh the Dispensed Liquid Carefully weigh the liquid dispensed using the weighing balance. Ensure the balance is calibrated and accurate.

Record the final weight (W2) of the liquid.

8. Calculate the Dispensed Volume Subtract the initial weight (W1) from the final weight (W2) to determine the weight of the liquid dispensed (W).

Convert the weight of the liquid dispensed to volume using the density of the liquid or the known density of the calibration solution.

Calculate the actual volume dispensed using the formula:

9. Compare with Expected Volume Compare the calculated volume dispensed with the expected volume (e.g., 50 μL for a 10-100 μL micropipette). Calculate the percent error to assess the accuracy of the micropipette calibration:

10. Adjust if Necessary If the percent error is within an acceptable range (typically ±2-5%), the micropipette is calibrated. Otherwise, adjustments may be needed. Consult the micropipette’s user manual for instructions on how to adjust the volume settings. Adjust carefully and recheck the calibration until the desired accuracy is achieved.

11. Record Calibration Data Keep a record of the calibration process, including the micropipette serial number, date of calibration, volume settings, calibration solution used, measured weights, calculated volumes, and any adjustments made.

12. Final Checks After calibration, perform a final check to ensure the micropipette is dispensing accurately and consistently across the volume range.
