Cleaning the pipettes

Do not disassemble pipettes. Do not douse or spray pipettes because that may damage electronics. When pipette is attached to the robot, power it off, and pull down the pipette to give it a gentle wipe.

Note: Never use acetone when cleaning the pipettes. Acetone will permanently damage the pipette! ABS plastic is extremely sensitive to Acetone. Avoid using 100% Ethanol or 100% Methanol when cleaning the pipettes (70% - 90% alcohol should be fine).


Do not clean the electronic components of the pipette

Wipe with isopropyl alcohol or ethyl alcohol

Wipe down the following parts of the pipette with either isopropyl alcohol or ethyl alcohol:

  • Pipette stem
  • Ejector
  • Body
  • Pipette cover
  • Pipette cap

Note: Bleach can also be used to clean GEN2 pipettes, but shouldn't be used to clean GEN1 pipettes. More information on how to identify whether you have a GEN1 or GEN2 pipette can be found here.

Contamination cleaning

If your pipette becomes contaminated with a known substance, there are specific cleaning steps that must be taken depending on the type of substance. Taking the routine cleaning and maintenance steps outlined above will not be sufficient if your pipette is cross-contaminated. Please contact support if your pipette becomes contaminated for assistance.

For aqueous solutions, rinse the contaminated parts with distilled water or 70 percent ethanol and air dry at 60°F.

For organic solvents, allow the substance to evaporate on its own or immerse the part in a detergent and then air dry.

For radioactive substances, place the pipette in a solution like Decon and then rinse and air dry.

For proteins, rinse the contaminated parts with a detergent, rinse, and air dry. DO NOT use alcohol as it will set the proteins.

For nucleic acids, rinse the contaminated parts in glycine/HCI buffer (pH 2) for 10 minutes, rinse with distilled water, and air dry.
