Improve process reliability with functional validation of air-displacement pipettes! Pipette Leak Testing Unit F I R S T The most frequent cause of inaccuracy in air-displacement 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. I Limit values for the commercially available singleand multichannel pipettes in the volume range 1 µl to 10 ml are pre-programmed. I Testing with and without tips I Test results in seconds I Patent pending

Pipette Leak Testing Unit (PLT unit) Leak rates and their detection According to monitoring of measuring instruments, air-displacement pipettes must be checked at regular intervals and the results must be compared with the ISO 8655-2 error limits. However, a calibration certificate only reflects the results at the time of testing. The time between these calibrations is crucial, since leaks can 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 leak rate is a measure of the quantity of material that flows...

Main Menu A wide variety of submenus can be selected from the main menu, e.g., pipette type, volume range, self-test, and settings (language, shut-off time, pressure units, etc.) Main Menu Pipette Type Self Test Switch OFF Settings... Auswahl select zurück back Testing with and without 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. Dynamic or static test? The dynamic test can rapidly determine whether a defective...
