FAQ

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.
