"The most common causes of inaccuracy in piston-action pipettes are leaks. These are caused by damage to the seals, pistons or tip-holding cones. Often invisible to the naked eye, they lead to significant volume errors. The PLT unit from BRAND, the leak tester for air-cushion pipettes, detects even the smallest leaks within seconds.
Pre-programmed limit values for standard single-channel and multi-channel pipettes in the volume range from 1 μl to 10 ml
Testing with and without a tip Test
result available within a few seconds
Patented
The PLT unit cannot replace regular gravimetric testing, but it safeguards the periods between calibrations through daily monitoring of the pipette. Even the smallest leaks are detected! This significantly improves the process reliability of the pipettes.
