Designed for the Environment

Go Green with the AQ Range of Advanced Discrete Analyzers

Designed to Minimize Waste

•  Segregated chemical waste and wash minimizes environmental impact
•  Only 500 – 600 μL of combined reagents and sample consumed per test
•  Add samples after a run has started - no recalibration required
•  Automated standard preparation and dilution of over-range samples
•  Will run up to 150 tests per hour
•  Tests programmable per sample to reduce analysis waste and time

•  Includes the ability to run overnight


and other international regulatory compliant methods are available. 

Principles of Discrete Analysis

The AQ series of Discrete Analyzers are flexible analyzers that uses the principle of discrete analysis, where each test occurs in a separate or discrete reaction vessel. They are ideal when many and varied tests are needed on different samples and/or individual results are needed in a short time.
