Pipette Calibration Key Features

  • Calibrations are performed by expert pipette technicians, using state of the art precision balances, who carry an extensive inventory of original manufacturer parts.
  • Choose from three standard test plans: QuickCal, FullCal, UKASCal or we can develop a test plan to suit your calibration requirements.
  • Gravimetric evaluation based on your regulatory needs. This assessment can be made against EI service limits or customer specification. Our technical team is able to discuss and guide you through this process.
  • We offer a competitive transparent service for pipette calibration with a simple pricing structure. We do not set a minimum charge for a day, you only pay the unit price agreed.

Pipette Calibration Limits

We can apply limits specified by you to the calibration.

However many customers do not have specific limits that they would like applied to the calibration results, but rely upon us as the service provider to let you know when a pipette is no longer performing. For this purpose we will apply our EI Standard Pipette Limits.

How We Perform a Pipette Service

Routine preventative maintenance and adjustments to your pipette ensures consistent and accurate results. Our technical department has access to a knowledge base that allows us to support an extensive range of equipment from all leading manufacturers.

Mechanical Inspection

The following parts to the pipette are examined:

  • Tip ejector mechanism (1)
  • Plunger (4)
  • Counter (4)
  • Nose cone (6)
  • Piston (5)
  • Seal and O’ring (7 & 8)

Condition is assessed:

  • Damage or corrosion to the piston
  • Damage to the nose cone
  • Tension ring or counter locking mechanism
  • Counter works correctly
  • Ejector pushes in fully so as not to foul the tip
  • Battery holds charge for an electronic pipettes
  • Check on each channel of a multichannel pipette
  • Leak test performed to confirm integrity of pipettes

O’Ring & Seal

The condition of the O’ring and seal is assessed (and will be replaced only when necessary). The piston mechanism will be cleaned and greased. Note for many Gilson pipette types greasing is not required.


Pipettes will be adjusted to maintain optimum measuring performance. European Instruments has the technical knowledge and specialist tools to perform these adjustments.
