What is a Micropipette?

A micropipette is a laboratory instrument used to measure and transfer small volumes of liquid, typically in the range of microliters (µL). These precision tools are critical in fields such as molecular biology, biochemistry, microbiology, and analytical chemistry, where accuracy and reproducibility are paramount. Uma Scientific’s micropipettes are engineered to ensure precise liquid handling, minimizing errors and enhancing experimental reliability.

Micropipettes operate on the air displacement principle, where a piston creates a vacuum to aspirate liquid into a disposable tip. The liquid is then dispensed into a receiving vessel with high accuracy. Uma Scientific offers a range of micropipettes, including fixed-volume, variable-volume, single-channel, and multichannel models, designed to cater to various laboratory requirements.

Types of Micropipettes Offered by Uma Scientific

Uma Scientific provides a diverse portfolio of micropipettes to suit different applications. Below are the primary types available:

1. Fixed-Volume Micropipettes

Fixed-volume micropipettes are designed to dispense a specific, predetermined volume of liquid. These are ideal for repetitive tasks where the same volume is used consistently, such as in quality control or educational labs. Uma Scientific’s fixed-volume micropipettes are user-friendly, cost-effective, and perfect for beginners or labs on a budget. Their robust design ensures durability, and they require minimal calibration, reducing maintenance time.

2. Variable-Volume Micropipettes

Variable-volume micropipettes allow users to adjust the volume within a specific range, offering flexibility for experiments requiring different liquid volumes. Uma Scientific’s variable-volume micropipettes feature a click-stop digital system for precise volume selection, ensuring no accidental changes during pipetting. These models are fully autoclavable, lightweight, and designed for ergonomic handling, making them suitable for prolonged use in research labs.

3. Single-Channel Micropipettes

Single-channel micropipettes are the most common type, used for transferring liquid from one container to another. Uma Scientific’s single-channel micropipettes are available in both fixed and variable-volume configurations, with volume ranges from 0.2 µL to 10 mL. These pipettes are equipped with a two-stage plunger for high accuracy and a tip ejector for easy, contamination-free operation.

4. Multichannel Micropipettes

For high-throughput applications, such as plate-based assays, Uma Scientific offers multichannel micropipettes in 8- and 12-channel configurations. These pipettes allow simultaneous transfer of multiple samples, significantly increasing productivity. Our multichannel models are fully autoclavable, feature low pipetting forces, and are designed to reduce the risk of repetitive strain injuries (RSI).

5. Electronic Micropipettes

Uma Scientific’s electronic micropipettes replace manual plungers with an electronic button, automating the pipetting process for enhanced precision and reduced user fatigue. These models are programmable to suit specific protocols, making them ideal for complex experiments requiring consistent performance.

6. Minipipettes

For educational settings or small-scale experiments, Uma Scientific’s minipipettes offer an affordable, compact solution. These fixed-volume pipettes are rugged, easy to use, and designed to withstand frequent handling by students or trainees.

How to Use a Micropipette: A Step-by-Step Guide

Proper use of a micropipette is critical to achieving accurate and reproducible results. Uma Scientific’s micropipettes are designed for ease of use, but following best practices ensures optimal performance. Here’s a step-by-step guide to using our micropipettes:

1. Select the Appropriate Micropipette and Tip: Choose a micropipette with the correct volume range for your experiment. Attach a compatible Uma Scientific pipette tip securely to the tip cone. Our universal tip cone ensures compatibility with a wide range of tips.
2. Set the Volume (for Variable-Volume Models): Rotate the plunger or thumb button to set the desired volume. Uma Scientific’s click-stop system ensures precise volume selection without accidental changes.
3. Pre-Rinse the Tip: Fill and empty the tip 2-3 times with the liquid you’ll be pipetting to equilibrate the tip and ensure accurate volume delivery.
4. Aspirate the Liquid: Hold the micropipette vertically, press the plunger to the first stop, and immerse the tip 2-3 mm into the liquid. Slowly release the plunger to aspirate the liquid into the tip.
5. Dispense the Liquid: Place the tip against the inner wall of the receiving vessel at a steep angle. Press the plunger to the first stop to dispense the liquid, then press to the second stop to expel any remaining liquid. Wipe the tip on the vessel’s wall while withdrawing to avoid contamination.
6. Eject the Tip: Press the tip ejector button to safely remove the used tip into a waste container, ensuring no cross-contamination.
7. Store Properly: After use, store the micropipette in an upright position using Uma Scientific’s carousel stand. Ensure it’s kept in a clean, dry environment at a temperature between -20°C and 50°C.

Pipetting Techniques for Optimal Performance

Uma Scientific’s micropipettes are designed to support various pipetting techniques to meet diverse laboratory needs. The two most common techniques are:

• Forward Pipetting: Ideal for aqueous solutions, this technique involves aspirating the liquid by releasing the plunger from the first stop and dispensing it by pressing to the first stop, followed by the second stop for complete expulsion. Uma Scientific’s micropipettes ensure smooth plunger movement for precise forward pipetting.
• Reverse Pipetting: Suitable for viscous or volatile liquids, reverse pipetting involves aspirating excess liquid by pressing the plunger to the second stop, then dispensing the desired volume by pressing to the first stop. This technique minimizes air bubbles and ensures accurate dispensing. Uma Scientific’s micropipettes are optimized for both techniques, with low pipetting forces and ergonomic designs.

Micropipette Calibration and Maintenance

To maintain accuracy, Uma Scientific recommends regular calibration of micropipettes, ideally every 3-6 months or after every autoclaving cycle. Our micropipettes are designed for easy calibration, adhering to ISO 8655 standards. Here’s how to calibrate your Uma Scientific micropipette:

1. Prepare Equipment: Use distilled water, a calibrated balance, and a thermometer to measure water temperature (ideally 22°C). Ensure a stable environment with controlled humidity and air pressure.
2. Perform Gravimetric Testing: Pipette a set volume of distilled water onto the balance and record the weight. Repeat 10 times to calculate the average and check against expected values.
3. Adjust if Necessary: If discrepancies are found, follow the calibration instructions in the user manual or contact Uma Scientific’s support team for assistance.
4. Autoclaving: Uma Scientific’s fully autoclavable micropipettes can be sterilized at 121°C for 20 minutes. Allow the pipette to cool to room temperature for at least two hours before use.
