BRAND PLT Unit

Improve process reliability with functional validation of air-displacement pipettes!

While the PLT unit cannot replace regular gravimetric testing, daily pipette checks can provide a safeguard during the periods between calibrations. Even the smallest leaks are detected! Process reliability for the pipettes is thus significantly improved.

To monitor measuring instruments according to ISO 8655, air-displacement pipettes must be checked at regular intervals and the results must be compared with the error limits contained in ISO 8655-2.

However, a calibration certificate only reflects the performance of the instrument at the time of testing.

The time between calibrations is crucial, since leaks can occur at any time, even immediately after testing. Well over 80% of pipettes sent in for repair have leaks and are outside their volume tolerances, even if they don’t drip.

The most frequent cause of inaccuracy in piston-operated pipettes is leakage. This arises from damage either to the seals, pistons, or tip cones. Often not detectable by the naked eye, leaks lead to significant volume errors.

The BRAND pipette leak tester (PLT unit) for air displacement pipettes finds even the smallest leaks within seconds.
