How to Store a Volumetric Pipette

Chemists and microbiologists use volumetric pipettes to measure precise liquid volumes. Each volumetric pipette is calibrated to deliver only a single volume, and it measures that volume with an accuracy of 0.20 percent or better. Volumetric pipettes are typically made of glass, so you can use the same pipette many times. Store your volumetric pipettes properly to ensure they are clean and intact the next time you need to use them.

Instructions

- 1
  Wash and rinse the pipette according to your laboratory protocol -- the solutions and procedures for washing vary depending on what you use the pipette for.
- 2
  Place the pipette on a drying rack or paper towels and allow it to dry completely.
- 3
  Lay the pipette gently in the compartment containing other pipettes of the same size if your lab uses drawer storage.
  
  Slide the pipette tip first into a hole in the pipette storage rack if your lab uses vertical storage.
