How do you service a pipette?
8 Easy Steps for Performing Pipette Preventive Maintenance
- Decontaminate the outside of the pipette.
- Inspect the general appearance of the pipette.
- Disassemble and clean the pipette.
- Replace the o-ring(s) and seal(s)
- Lubricate (if applicable)
- Re-assemble the pipette and check functionality.
How accurate are Gilson pipettes?
For applications such as DNA sequencing and biochemical procedures that require tiny, valuable, samples, two Pipetman models provide exceptional accuracy and precision, from 0.1 to 2 µl for Model P2 and 0.5 to 10 µl for Model P10.
How often should pipettes be calibrated?
every 3 to 6 months
The Clinical and Laboratory Standards Institute (CSLI) recommends that pipettes (single and multi-channel) and automated liquid handlers be calibrated every 3 to 6 months. A minimum of two volumes must be tested (nominal and lowest setting) with ten replicates at each volume.
How do you know if a pipette is calibrated?
The most common way to check your pipette accuracy is by weighing water. The density of water is 1 g/mL. This means that every microliter (µL) should weigh 0.001 g. In other words, if your pipette is accurate, the amount of water you dispense will equal the amount the water weighs.
What are some common pipette handling errors?
Common pipetting errors include:
- Failure to Pre-Wet Pipette Tip.
- Disregarding Temperature.
- Tip Wiping.
- Choosing the Wrong Pipetting Mode.
- Working Too Quickly.
- Pipetting at an Angle.
- Using the Wrong Pipette Tips.

What is used to clean pipettes?
Open the pipette, immerse the parts in a detergent solution, such as Deconex® 12 Basic. Rinse well with distilled water and allow to dry. DNA can be eliminated by immersing pipette parts in at least 3% (w/v) sodium hypochlorite for at least 15 minutes (2,3). Rinse well with distilled water and allow to dry.
How do you clean a pipette tip?
Start cleaning by rinsing the pipette with a strong detergent and then wash the pipette with distilled water several times. Air-dry it at 600C and finish the cleaning by conducting a wipe test to ensure that all of the radioactive substance is gone.
How is a pipette calibrated?
The calibration of pipette is carried out by gravimetric method. When determining the volume of water, the accuracy of measurements is effected by ambient temperature, atmospheric pressure and relative humidity. These factors are usually combined to give the Z factor, used in calculation of volume of water.
Can you clean pipette tips?
Open the pipette, rinse the contaminated parts thoroughly with distilled water, and allow to dry. It is advisable to clean the tip cone and lower part of the tip ejector with distilled water more frequently if acids or alkalis are handled. Clean as described in “Aqueous solutions and buffers.”
What is the largest source of pipetting problems?
Human error is the largest source of pipetting problems, followed by liquids sticking to the tips, and loss of accuracy when working with viscous liquids (multi-option select question, chart depicts the percent of survey respondents who experienced these various pipetting errors).
