According to monitoring of measuring instruments, air-displacement pipettes must be checked at regular intervals and the results must be compared with ISO 8655-2 which is the standard for piston-operated volumetric appartus.
A calibration certificate only reflects the results at the time of testing. The time between these calibrations is crucial, since leaks occur at any time. Well over 80% of pipettes sent in for repair have leaks and are outside their volume tolerances, even if they don’t drip.
The NEW Brand PLT – Pipette Leak Test is able to test your pipette to find even the smallest leaks.
This unique instrument provides a safeguard between calibrations. Process reliability of your pipette is significantly improved.
Test with and without a tip!
To check the overall pipette system, the test is conducted with mounted, unused tip.
When a leak has been identified the test can be repeated without a tip to determine whether the leak arises from the tip cone/tip coupling region.
