Micropipettes are essential tools in scientific laboratories, enabling the precise measurement and transfer of small volumes of liquids. Choosing the right micropipette is crucial to ensure accuracy in experiments and procedures, thus optimizing the quality and reproducibility of results.
What is a Micropipette and What is it Used For?
A micropipette is a laboratory instrument designed to aspirate and dispense very small volumes of liquids, usually in the microliter (µL) range. Its main function is to allow the precise handling of liquids in various analytical techniques, being fundamental in fields such as molecular biology, analytical chemistry, and biomedical research. Precision in measuring and transferring liquids is vital for obtaining reliable and reproducible results in scientific experiments.
Classification of Micropipettes
Micropipettes can be classified according to different criteria, facilitating their selection based on the specific needs of the laboratory.
Types of Micropipettes by Volume
- Fixed Volume Micropipettes:
Designed to dispense a specific and constant volume, they ensure high precision in repetitive tasks where the same volume is always required. - Variable Volume Micropipettes:
These allow adjusting the volume within a specific range, providing flexibility to handle different volumes with a single tool. They are versatile and common in laboratories with diverse pipetting needs.
Types of Micropipettes by Channel
- Single-Channel Micropipettes:
Equipped with a single tip, they are used to transfer liquids from one container to another. They are ideal for applications that do not require simultaneous multiple pipetting. - Multi-Channel Micropipettes:
Equipped with multiple tips (usually 8 or 12), they enable the simultaneous aspiration and dispensing of liquids in several samples. These are especially useful in techniques involving microtiter plates, such as ELISA assays.
How to Choose the Right Micropipette for Your Laboratory
Selecting the appropriate micropipette is essential to ensure precision and efficiency in the laboratory. Here are some key factors to consider:
- Volume Range:
It's essential that the micropipette covers the volume range typically handled. Using a micropipette with a suitable range for the desired volume improves the precision and accuracy of measurements. - Type of Liquid:
The physical properties of the liquid (viscosity, volatility, density) can influence the choice of micropipette. For example, for viscous or volatile liquids, positive displacement micropipettes are more suitable. - Frequency of Use:
If the micropipette will be used intensively, it is advisable to opt for ergonomic models that reduce user fatigue and minimize the risk of repetitive strain injuries. - Required Precision and Accuracy:
Depending on the sensitivity of the experiments, it may be necessary to choose micropipettes that offer high levels of precision and accuracy. - Budget:
While quality is paramount, it's important to balance laboratory needs with the available budget, seeking options that offer good value for money.

Frequently Asked Questions
What is the Difference Between a Micropipette and a Pipette?
The main difference lies in the precision and volume of liquid they can handle. Traditional pipettes are generally used to measure and transfer larger volumes and offer less precision compared to micropipettes, which are designed to handle very small volumes (microliters) with high accuracy.
How Often Should a Micropipette Be Calibrated?
Micropipettes should be calibrated regularly to ensure their accuracy. The frequency depends on usage and laboratory policies, but generally, it is recommended to calibrate them every 3 to 6 months.
How to Properly Clean a Micropipette?
Proper cleaning of a micropipette is essential to maintain its optimal functionality and avoid cross-contamination. It is recommended to regularly disinfect the exterior with appropriate solutions and, periodically, disassemble the micropipette to clean and lubricate the internal parts according to the manufacturer’s instructions.
Selecting and properly maintaining micropipettes is fundamental for the success of laboratory operations. An informed choice and proper maintenance ensure precision and reliability in experimental results, contributing to the advancement of science and technology.
