1. Use a suitable tip:
In order to ensure better accuracy and precision, it is recommended that the pipetting volume be within the range of 35%-100% of the tip.
2. The installation of pipette tips:
For most brands of pipettes, especially multi-channel pipettes, it is not easy to install the pipette tip: in order to pursue a good seal, you need to insert the pipette sleeve handle into the pipette tip and turn it left and right or shake it back and forth to tighten it forcefully.
There are also people who use the pipette to repeatedly hit the tip to tighten, but this operation will cause the tip to deform and affect the accuracy, and severely damage the pipette, so such operations should be avoided. RAININ’s multi-channel pipette does not have an O-ring, and is matched with a tip with a front stop point. It can achieve an ideal seal with just one light pressure, which is a good news for users of multi-channel pipettes.
3. The immersion tilt and depth of the tip:
The immersion tilt of the tip is controlled within 20 degrees of inclination, and it is better to keep it upright; the tip immersion depth is recommended as follows:
Pipette specifications Tip immersion depth：
2μL and 10μL: 1 mm
20μL and 100μL: 2-3 mm
200μL and 1000μL: 3-6 mm
5000μL and 10mL: 6-10 mm
