Pipette Accuracy Management From A&D Weighing

SAN JOSE, CA--(Marketwire - June 17, 2010) -  A&D Weighing is proud to announce the launch of its new Pipette Accuracy Management Series of products: The AD-4212A/B-PT and FX-300iPT Pipette Accuracy Testers, along with the AD-1690 Leak Tester.

The Pipette Accuracy Testers from A&D Weighing allow users to determine the performance of their pipettes in accordance with the gravimetric method specified in ISO 8655. A&D has substituted the typically bulky and difficult to transport analytical balance with its compact AD-4212A and AD-4212B production weighing units, which are ideal for evaluating pipettes in the volume range of 1 to 10,000 microliters. The FX-300i-PT can be used for daily verification and simplified inspection. These all come conveniently packaged with all the necessary hardware and software required to implement a cost effective method for evaluating pipettes.

The triple range AD-4212B-PT (110g/31g/5.1g x 0.1mg/0.01mg/0.001mg) can measure down to microgram levels, allowing the user to test pipettes with volumes as small as one microliter.

All A&D pipette testers come with an ergonomically designed constant humidity evaporation trap, which greatly minimizes the effect of evaporation on test results. It also functions as a breeze break. The pipette is inserted at a 45-degree angle, rather than the vertical orientation required for similar devices. This enables the user to maintain correct pipetting technique, and ensure the accuracy of the results.

The other key component A&D provides is its WinCT Pipette software. This intuitive and easy to use package connects the balance to a PC for direct weighing data transfer and test result analysis.

An attractive custom aluminum carrying case holds all the system components and is ideally suited for pipette calibration service companies who travel to their clients and for companies that have pipettes in multiple locations.

To round out the Pipette Accuracy Management Series offering, the AD-1690 Leak Tester allows for instant determination of pipette integrity. Since most pipette failures happen due to damaged seals, o-rings, pistons or tip-holders which compromise the air tightness of the pipettes, the AD-1690 allows the user to perform a quick and simple test to determine the condition of the pipette. The AD-1690 applies a vacuum to the pipette and the subsequent rate of air infiltration is measured. A pass-fail result is then indicated. Users can also easily establish their own custom test parameters. Additionally, the AD-1690 is also designed to test for leakage in small pumps, containers, and piping (capacity up to 50 ml).
