1. Suitable suction head

In order to ensure more precision and accuracy, it is recommended that the water absorption rate is within the measurement range of 35%-100% of the water absorption head.

2. Install the suction head

For most brand-name pipettes, especially multi-channel pipettes, installing the suction head is not easy: in order to pursue perfect and excellent sealing performance, the suction head must be inserted into the pipette sleeve, rotating up and down or rocking back and forth to tighten. Some people will use the pipette often bump the suction head to tighten, but if this operation will cause the suction head deformation and damage the accuracy, more serious will damage the pipette, so it should avoid such actual operation.
