Description

The AQ400 robotic sampling arm works in conjunction with a stepper motor-drivensyringe that is responsible for aspirating, dispensing and mixing accurate and precise quantities of sample and reagent in miniaturized test tubes called reaction wells.
The sample and reagent mixture are incubated in heated reaction wells until the reaction is complete. A single aliquot is then transferred into a 10 mm path length optical glass cuvette where the absorbance is read. Each sample is read in the same cuvette, in the same position in front of the detector. This is similar to SEAL colorimetricflow systems, known for their high reproducibility and lowest detection limits.
The flow through cuvette eliminates the issue of reaction well variability and scratching found in direct read discrete systems. In the SEAL AQ series, liquid is moved notthe cuvette – fewer moving parts equal higher stability and reliability of the system.
Once the absorbance is read, the glass cuvette is thoroughly cleaned and checked,ensuring no carryover or cross contamination.

Your environmental analytical chemistry has just got easier with the SEAL AQ400 Discrete Analyzer . This compact, bench-top analyzer has been designed by chemists to address the needs of environmental laboratories requiring high levels of automation, a wide range of chemistries, limits of detection that ensure compliance with regulatory requirements and integration with LIMS. Like the other Discrete Analyzers in the SEAL range, the AQ400 will give you the best analysis and eliminate problems inherent in analyzers designed for clinical use. SEAL Analytical has the largest installed base of Discrete Analyzers in the USA and we continue to develop the software and hardware for the specific needs of environmental samples.
