They can also be used with different pipette aids or helpers to aid within the aspiration and dispensing of fluids.
These pipettes are effective at staying quite exact and correct. Nevertheless, because they depend on air displacement, they are issue to inaccuracies caused because of the transforming setting, specifically temperature and user procedure. For these motives, this tools must be diligently preserved and calibrated, and customers needs to be qualified to physical exercise correct and reliable method.
