Frequently Asked Questions

What are pipettes?

Pipettes are one of the most utilized instruments in the scientific and medical fields. These instruments work by aspirating a volume of liquid from one source and releasing the specific amount to another container. Pipettes were designed to transfer precise amounts of liquid between one or more containers. They come in various types and designs with different levels of accuracy. Sometimes your instrument may need to undergo a pipette calibration or repair to deliver the most accurate measurement.

To achieve the most precise results with your work, a high degree of accuracy is required. Don’t let your work suffer because of a faulty pipette!

  • It feels sticky
  • It does not aspirate or dispense evenly
  • It does not aspirate at all
  • It does not power on or loses battery power quickly
  • Your results just do not seem right

The calibration of pipettes is carried out by the gravimetric method as per ISO 8655. When determining the volume of water, the accuracy of measurements is affected 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.

According to the Clinical & Laboratory Standards Institute (CLSI), you should calibrate your pipettes every 3–6 months or before they’re put into service. If you fail to do so, pipette readings may become inaccurate and unreliable.

The main objective of pipette calibration is to make sure that dispensing is carried out with the intended accuracy.

Raeyco offers both options, but on-site calibration may be more appropriate if you have a large number of pipettes. Pipettes can be easily shipped to either our B.C. or Ontario offices for calibration in our lab.

The most common way to check your pipette accuracy is by weighing water. The density of water is 1 g/mL. Z correction factors take into account water density and air buoyancy during weight at the corresponding test temperature. As the measured values (in g) are balance readings, a correction taking into account water density and air buoyancy is used as per ISO 8655.
