It allows for accurate and handy aspiration and dispensing of liquids employing disposable strategies. Pipettors are generally Employed in superior-throughput purposes, in which repetitive pipetting is necessary.
They can be Utilized in microbiology labs and work on the basic principle of air displacement for ideal accuracy.
Using pipettes minimizes the chance of contamination considering that they frequently have disposable tips that may be changed in between samples, stopping cross-contamination.
An additional element to think about is whether you would like a manual or electronic unit. Below you'll discover solutions out there from both equally types to satisfy your unique requires.
