Why do I get different calibration results in my laboratory?

  • A number of things can cause your laboratory calibration results to differ from results in our facility:
  • (a) Testing method (gravimetric vs photometric)
  • (b) Tips used – all MLA pipettes calibrated with VistaLab tips
  • (c) Pipetting technique and form- all MLA pipettes calibrated according to ISO 8655
  • (d) Equipment sensitivity
  • (e) Environmental conditions

What is the recommended routine maintenance for an MLA pipette?

  • (1) Remove, clean, inspect and replace the nozzle insert as needed.
  • (2) Wipe down the outer and inner surfaces of the pipette body with a soft cloth, tissue or Q-tip dampened with alcohol to remove any dirt or powder residue
  • (3) Lubricate the plunger with silicon oil and replace the inner piston seals as needed.
  • (4) Verify performance and adjust calibration as needed

How often should routine maintenance and calibration be performed?

  • VistaLab recommends performing routine maintenance every 6-12 months depending on frequency and conditions of use.
