What Causes the Inconsistency of Multi-channel Pipette Tips?

Pipettes are often used in laboratories, schools, research institutes, hospitals, etc. Among the many pipette types, multi-channel pipettes are pipettes with multiple tips, so some users are in use. It is found that the pipette tip suction amount is inconsistent. What causes the multi-channel pipette tip suction amount to be inconsistent? How to solve it?

Reason one: the piston is polluted

Pipettes that use long or irregular operations (such as pipetting the liquid beyond the range of the tip will cause liquid to flow into the pipette) can cause the pipette to accumulate.


After opening, you can use a cotton swab or a soft brush to pick up a small amount of water to clean the stains. For more stubborn substances, rinse the pipette with plenty of water, then dry naturally or in an oven at 60 °C. Do not use organic solvents for cleaning or ultrasonic cleaning.

Reason two: the tip does not match the pipette

The pipette has been used for a long time, and the tip is often replaced. The replacement tip may not be a regular tip or a matching tip, which may easily lead to inconsistent pipette tips.


Replace the tip, it is recommended to use the original pipette tip.
