VEVOR’s Micropipettes as Essential Tools In Laboratory Accuracy

With laboratory accuracy being the backbone of scientific inquiry, experimentation, and analysis, micropipettes are indispensable instruments within laboratory settings, forming the bedrock of precise liquid handling and measurement.

Whether in pharmaceuticals, biotechnology, academic research, or clinical diagnostics, the precision and reliability of measurements directly influence the validity and reproducibility of results. Micropipettes, in this regard, serve as the frontline apparatus facilitating the transfer and dispensing of minute volumes of liquids with unparalleled accuracy.

Micropipettes are precise laboratory instruments used to measure, transfer, and dispense small volumes of liquid, typically in the microliter (µL) range. They are essential tools in scientific research, diagnostics, and various laboratory procedures where accurate volume measurements are crucial.

Different Types Of Micropipettes

There are different types of micropipettes, which all cater to specific laboratory requirements. By knowing each micropipette type and using them correctly, you can ensure accuracy, precision, and efficiency in liquid handling and tasks across scientific disciplines.

From air and positive displacement micropipettes to multichannel, electronic/digital, variable volume, repeater pipettes, nano and pico-pipettes, and adjustable space micropipettes, there are more than enough options for people’s scientific needs. 

Air & Positive Displacement Micropipettes

Displacement micropipettes are the most common type. The air displacement microppete works based on air displacement within the pipette tip. As the plunger is depressed to the first stop, it aspirates the liquid by creating a vacuum.

Upon depressing further to the second stop and releasing, the liquid is dispensed. They come in various volume ranges, from microliters (μL) to milliliters (mL), so they are ideal for general liquid-handling tasks.

On the other hand, the positive displacement micropipettes use a disposable piston to come into direct contact with the liquid. This design is advantageous when dealing with volatile or viscous liquids or when high precision is required for smaller volumes, as they are less prone to inaccuracies caused by air bubble formation.

Digital Micropipettes

The digital micropipette incorporates electronic mechanisms to accurately control aspirating and dispensing liquids. With features like programmable settings, adjustable speeds, and memory functions, they provide accurate volume readings, often with user-friendly interfaces.

Variable Volume Micropipettes

This micropipette allows the adjustment of the volume setting within a specified range, making them versatile for various applications and canceling the need for multiple micropipettes. This feature makes them essential in research settings where volume flexibility is crucial.

Multichannel Micropipettes

Multichannel micropipettes allow aspirations and dispensing from various channels simultaneously. These channels can be 8, 12, or 16. They efficiently reduce the work time, especially for tasks that could have been repetitive, like filling multiwell plates.

Various Applications of Micropipettes

Micropipettes are widely used in various scientific fields. With their ability to precisely and accurately handle small liquids, some sectors find them indispensable. They include:

Biotechnology and Molecular Biology

This industry uses micropipettes for various procedures, including DNA amplification and sequencing, sample preparation for genomics and proteomics, and molecular cloning and manipulation. Also, Biochemistry uses it for protein analysis and purification, enzyme assays and kinetic studies, and western blotting

Clinical and Medical Laboratories

Medical laboratories and clinics handle a large number of liquid samples. From blood analysis and immunoassays to drug testing and pathology, these little heroes ensure clinical tests are well done. They also use them for pathology, bodily fluid testing and general diagnostic testing.

Pharmaceutical and Drug Development

Drug formulation and analysis in pharmaceuticals greatly rely on pipettes. From quality control to assay development and high throughput, various aspects of drug discovery, formulation and analysis thrive due to the impact of micropipettes.

Environmental and Food Sciences

Sample analysis in environment and food science greatly depends on micropipettes. Samples like water and soil, among others, are handled with micropipettes during food testing, quality control, and analysis.

How To Extend The Lifespan Of Micropipettes

Adhering to certain practices can help significantly extend your micropipette's lifespan. Adequate cleaning and proper maintenance make a difference in functionality, efficiency, and longevity. Therefore, we will discuss some standard cleaning and maintenance practices to keep your micropipette reliable for a long time.

Cleaning

Carefully clean the micropipettes regularly to keep them nice and prevent damage. Use a mild detergent solution to clean the exterior and employ a lint-free cloth to remove any spilled liquid or contaminant.

Avoid harsh chemicals to prevent damage. Also, clean and change pipette tips frequently to prevent cross-contamination. Also, ensure you use high-quality, compatible tips for your micropipettes.

For deeper cleaning, periodically decontaminate the pipette with a solution of 70% ethanol or isopropyl alcohol, ensuring the solution doesn’t seep into the pipette body, especially the internal mechanisms.

Maintenance

Regularly calibrate pipettes according to manufacturer guidelines or accredited calibration service, and ensure you use appropriate and standard calibration tools to check their accuracy. Regularly oil and lubricate pipettes that require them, using the lubricants recommended by the manufacturer.

Store micropipettes in a clean, dust-free environment without exposing them to extreme solutions or corrosive substances.

FAQs About Micropipettes

How accurate are micropipettes?

High-quality micropipettes can deliver precise and accurate volumes, often within ±1–2% of the set volume. Calibration and proper technique are essential for maintaining accuracy

How do I choose the right micropipette?

When choosing a pipette, consider the volume range, accuracy, sample type, application and usage, and ergonomics, ensuring you choose a micropipette that best suits your needs.

How often should I calibrate my micropipette?

There is no fixed time for calibrating micropipettes. Some labs calibrate them after some uses, and it is essential to calibrate them at least once every year.
