If your density is outside the tolerance, additional adjustments to the pipette could be necessary.
Calibration ought to be carried out right after any upkeep or repair work on the micropipette to verify that it meets the demanded specs.
remember that temperature, atmospheric pressure, and liquid viscosity and density can drastically influence this pipette's functionality.
Aspiration of liquid: The plunger on the micropipette has two stops. For aspirating, press the plunger to the primary cease and dip the tip tip into the fluid for being aspirated. Release the plunger but make get more info certain the tip is Within the liquid right up until the plunger regains its authentic place.

These pipettes are capable of staying really exact and accurate. However, considering that they count on air displacement, They may be subject matter to inaccuracies brought on by the transforming setting, specifically temperature and user approach. For these motives, this equipment need to be cautiously taken care of and calibrated, and users should be skilled to training suitable and constant procedure.
