Factors Affecting The Accuracy Of The Pipettor

(1) Temperature: When the room temperature is low, the hand temperature is high, it will cause air to expand, and errors often occur when inhaling cold solutions

(2) Air tightness: The joint between the tip and the pipettor body, as well as the long-term wear between the columns in the pipettor, will cause errors

(3) Suction speed: it is easy to cause bubbles in the tip and pollute the pipettor head

(4) Volatilization of reagents: When absorbing highly volatile reagents, steam enters the pipette head and the internal pressure increases. As a result, when pressing out the liquid, the pressure increases, resulting in errors. Solution: Repeated suction 4-5 times can improve.
