Frequently Asked Questions





How often do I need to get my pipettes calibrated?
Pipettes need to be calibrated based on their usage and your laboratories Standard of Procedures (SOPs). Pipettes should be calibrated at least once a year to make sure that they are accurate and receiving the preventive maintenance that they need. Some laboratories require their pipettes to be certified every quarter or biannually.

Why is my pipette dripping or leaking?
There may be a few different problems with your pipette if it is leaking or dripping.
  1. Your pipette could be dripping or leaking because there is corrosion inside of your pipette. Your seal is no longer working correctly; therefore you need internal cleaning and maintenance of your pipette.
  2. Sometimes dripping or leaking is also caused by a shaft issue. The Pipette Solution can identify this problem by changing the seal and then interchanging the shaft.
  3. The tips that you are using may not be the right fit for your pipette. Check with your pipette tip representative.

Do tips make a difference while using pipettes?
Yes, tips do make a difference when using your pipettes. If the tips do not fit the pipette correctly, there will be leaking or incorrect volume drawn up while pipetting. Again, please check with your pipette tip representative.

What are recommended handling techniques for pipettes?
It is important to handle your pipettes properly to maximize their longevity and maintain accurate readings. The Pipette Solution has created ten tips to properly handle your pipettes.
  1. Always store your pipettes upright. Leaving them flat on the bench can cause corrosion.
  2. Never lay the pipette on its side when liquid is in the tip. This could cause the liquid to enter the shaft and piston area of the pipette, which will result in corrosion.
  3. When using a pipette, push the plunger down to the first stop and hold, then insert the tip into the liquid at a vertical or 20 degree angle. Slowly release the plunger so the liquid goes into the tip without a sign of bubbles.
  4. Always abide by the volume usage specified by the manufacturer. Do not try to use a 200ul-1ml pipette to draw up 50ul of liquid.
  5. Teach new laboratory members how to use the pipettes; do not assume that they know proper technique.
  6. Do not open the pipettes, they lose calibration when opened and are no longer covered by the warranty.
  7. When removing the tip from the pipette, use the ejector button or lightly pull the tip off of the shaft.
  8. Calibrate your pipettes at least on an annual basis to ensure that they are in specifications and cleaned thoroughly.
  9. Take a scale and check your pipettes every few months to ensure that your pipettes are close in specifications.
  10. Draw up liquid every so often and keep it in your tip at vertical. Count to 10 and make sure that your pipette is not leaking. If so, call The Pipette Solution to fix your problem.

What's the difference between checking the pipettes and calibrating the pipettes?
Think of checking the pipette as more of a physical inspection. This is the process in which volume is drawn up several times and the volume is measured to ensure accuracy of the pipette. No internal inspection is performed.

Calibrating is when the pipettes are checked initially to see if they are accurate and then opened and cleaned internally. Lubricating and seal changing occurs and then the pipette is calibrated to manufacturers. specifications.
