WKM 5 to 50 µL, 10 to 100 µL, 100 to 1000 µL Variable Volume Plastic Micropipette (Set of 3 Pcs) is a precise and indispensable tool used in laboratories for accurately measuring and transferring small volumes of liquids. It is a handheld device commonly found in molec µLar biology, biochemistry, cell c µLture, and other scientific disciplines where precise liquid handling is crucial.
Micropipettes come in various types, including single-channel and m µLti-channel pipettes, each designed for specific applications. The basic design consists of a piston, which moves up and down within a barrel. The micropipette has a disposable tip that attaches to the end of the barrel. When the plunger is depressed, air is expelled from the tip, creating a vacuum. When the plunger is released, the vacuum draws the liquid into the tip.
The volume to be aspirated can be adjusted using a dial or plunger, allowing users to select the desired volume with high accuracy and precision. Micropipettes come in different volume ranges, from microliters (μL) to milliliters ( ml). Common micropipette volumes include 1μL, 10μL, 100μL, 1000μL (1 ml), and others, depending on the specific needs of the laboratory work.
Using a micropipette correctly is essential for obtaining accurate res µLts. Proper technique involves ensuring the tip is securely attached, pre-wetting the tip to reduce surface tension, aspirating the liquid at the correct volume, dispensing the liquid accurately, and ejecting the tip without introducing contamination.
Micropipettes are crucial in various laboratory procedures, such as preparing and dispensing reagents, diluting samples, transferring cells or microorganisms, and setting up PCR reactions. Their precision and accuracy significantly impact experimental outcomes, making them invaluable tools for researchers, technicians, and scientists working with small volumes of liquids.
Reg µLar maintenance and calibration of micropipettes are essential to ensure their continued accuracy and performance. Calibration helps verify that the volume settings are correct and that the pipettes are delivering the expected volumes accurately.
In conclusion, the micropipette is a fundamental tool in modern laboratories, enabling precise and efficient handling of small liquid volumes. Its versatility, accuracy, and ease of use have revolutionized liquid handling in scientific research, leading to more reproducible and reliable res µLts in various fields of study.
