Pipette Calibration
What is Pipette Calibration?
  • Pipette calibration is a vital element that a good laboratory should consider for any lab regime that requires precise volumes of liquid transfer or dilution.
  • It can be a complex process when all components of the procedure are allowed for a certain possibility, particularly when there are numerous makes and models of pipettes on the market and different calibration protocol options to consider.
  • Pipettes supplied by Fine Care Biosystems hold its individual calibration certificate as per ISO 8655 standards. Calibration of each pipette has been checked at three variable volumes for ten readings.
  • To ensure precision and accuracy of each pipette, regular testing and calibration verification of the instrument is necessary. Fine Care Biosystems provides a comprehensive solution for primary checking and calibrating the devices, particularly to the users without any complex measurement.

Different types of calibration with process overview

  • Pipette calibration can be carried out in different types and processes. One of the most commonly used methods is gravimetric analysis, where calibration is predominantly undertaken by laboratories as per the standard mentioned in EN ISO 8655 guideline. This method is preferred for traceability to simplicity to a perfect measure.
  • Gravimetric analysis is generally regarded as the economical ways of calibration. Under this method, distributing samples of distilled water is set into a receiving container in an accurate analytical balance. The denseness of water is a known constant, barometric pressure, temperature and humidity are recorded and kept within certain limits and hence the mass of the dispensed sample gives a precise indication of the volume distributed.
  • Each element of this process is audited itself to ensure compliance and chain of custody for precise calculations.
  • Apart from gravimetric analysis, there are colorimetric methods in use but are often sued for examining pipettes and for non-accredited calibration.
