As the most commonly used manual adjustable precision pipette in liquid operation, some wrong operations will bring errors to the operation itself in the process of use, some will cause damage to the machine, which is simply summarized as follows:

NO1.

Error: When assembling the suction head, the pipette repeatedly impinges the suction head, which is tight;

Correct: Insert the suction head, turn around gently rotate the upper tight suction head;

Analysis: The impact will cause the internal gear combination of the pipette loose, long-term operation will affect the accuracy of the pipette;

NO2.

Error: Suction head and pipette mismatch, affecting air tightness;

Correct: Select and pipette matching, quality assurance suction;

Analysis: The mismatch of suction head is mainly manifested as the impact on air tightness. Will directly affect the accuracy of the pipette, usually the pipette operation will be less than the set amount;
