mikropipeteille

Mikropipetteille are essential tools in many scientific laboratories, particularly in molecular biology, biochemistry, and clinical diagnostics. They are precision instruments designed to accurately and precisely measure and transfer very small volumes of liquids, typically ranging from fractions of a microliter to several milliliters. The name "mikropipette" derives from the Greek word "mikros" meaning small, and "pipette," a laboratory device for transferring liquids.

The fundamental principle of a mikropipette's operation relies on air displacement. Most modern mikropipetteille use a piston-driven system. When the plunger is depressed and released against a disposable plastic tip, it creates a vacuum that draws liquid into the tip. The volume is set using a calibrated dial or button, which adjusts the stroke of the piston. A second press of the plunger expels the liquid. Different mikropipetteille are designed for specific volume ranges, and selecting the correct one for the intended volume is crucial for accuracy.

There are several types of mikropipetteille, including fixed-volume and variable-volume models. Variable-volume mikropipetteille are more common due to their versatility. They can be single-channel, designed to handle one liquid at a time, or multi-channel, which allow for the simultaneous transfer of multiple liquid samples, significantly increasing throughput in applications like 96-well plate assays. Furthermore, digital mikropipetteille offer electronic volume setting and dispensing, often with programmable features for enhanced accuracy and ease of use. Proper calibration and maintenance are vital for ensuring the long-term accuracy and reliability of mikropipetteille.
