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.
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.
- Test limit values for all commercially available single- and multichannel pipettes in the volume range 1 μl to 10 ml are pre-programmed. - Test with and without tips to assist in leak source diagnosis - Test results in seconds - Patent pending
