Pipette Accuracy Testers
Inaccurate pipetting can ruin all your research. However, having scores of pipettes checked regularly by an outside company is unnecessarily expensive. With A&Ds pipette accuracy testers, you can easily determine pipette accuracy by yourself whenever you want, based on any criteria – manufacturers, ISO8655, or even your own.
The gravimetric method is the most common way of knowing the performance of variable-volume pipettes, in which pipette volume is determined based on the mass value of distilled water dispensed from the pipette.
Evaporation Trap
One of the diffi culties in weighing a small quantity of liquid (e.g. 50 ìL or less) is controlling the environment to minimize errors due to loss of evaporation. The evaporation trap maintains high humidity inside and prevents evaporation of the test liquid. It is no longer necessary to set up and adjust the humidity of an entire room.
Carrying Case
The pipette accuracy tester comes packed neatly in a portable carrying case, which allows for convenient transport to off-site locations.

Most pipette failures happen due to damaged seals, o-rings, pistons or tip-holders compromising the airtightness 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 approx. 50 ml), and especially micropipettes.
Quick Testing
Completes leak testing in less than 5 seconds.
Leak Detection by Depressurization*
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.
Three Types of Attachments
Covers three different tip sizes of pipettes, with capacities ranging from 2ìL to 10,000ìL.
