The Maintenance and Precautions of the Pipette

1. After using the pipette, set the pipette range to the maximum value and place the pipette vertically on the pipette holder.
2. Do not place the pipette horizontally or upside down when there is liquid in the tip of the pipette to prevent liquid from flowing into the pipette to corrode the pipette. The pipette should be hung on the pipette holder.
3. If the liquid accidentally enters the pipette, the contaminant should be removed in time.
4. If there is liquid dripping after adding liquid, it means that the pipette leaks or the tip are not tight. It is recommended to insert the tip. If the liquid is still dripping, it is recommended to replace the pipette.
5. Pipettes that require high-temperature disinfection should first check whether the pipette used is suitable for high temperature disinfection before processing.
6. When sucking the liquid, be sure to release the thumb slowly and smoothly. Never let it suddenly loosen, in case the solution is sucked too fast and flushed into the liquid extractor to corrode the plunger and cause air leakage.
7. When taking up serum protein solution or organic solvent, a “liquid film” will remain on the inner wall of the tip, and the volume of the second extraction will be larger than the first volume.
8. The removed tip must not be mixed with the new tip to avoid cross-contamination.
9. Select a pipette of the appropriate range, do not use a large-scale pipette to remove small volumes of sample
