Most pipette failures happen due to damaged seals, o-rings, pistons or tip-holders compromising the air-tightness of the pipettes. With the AD-1690 leak tester, you can instantly determine whether a pipette needs repairing or not. The AD-1690 is designed to test for leakage in small pumps, containers, piping (capacity up to approximately 50 ml), and especially micro-pipettes.
Features:
- Quick testing
- Completes leak testing in less than 5 seconds
- Leak detection by depressurization (a pressurization method is available upon request)
- Changes pressure by evacuating air instead of injecting it, so no dust enters the measured object.
- Replaceable air filter
- Protects the leak tester from dust when it intakes air and is easily replaced
- RS-232C interface
- Outputs data to a PC or an A&D peripheral device such as the AD-8121B or AD-1688 (sold separately)
- Three types of attachments
- Covers three different tip sizes of pipettes, with capacities ranging from 2 µL to 10,000 µL
