SEAL DISCRETE ANALYZER AQ270

discrete analyzer - USEPA - nutrients - environmental

 

Brand: SEAL
Product: DISCRETE ANALYZER AQ270

Description:

The AQ270 Discrete Analyzer is the ideal entry level Discrete Analyzer, rounding out the SEAL Analytical nutrient analyzer family to bring automated nutrient analysis to every size laboratory and budget. The AQ270 Discrete Analyzer delivers the benefits of discrete analysis, but with a smaller footprint and lower sample throughput- ideal for laboratories with less space or smaller workloads. Designed specifically for nutrient analysis on environmental samples, it is perfect for immediate results on many different parameters from the same sample.
In the AQ270 all samples are read in exactly the same way in an optical glass cuvette, giving you the best reproducibility, the lowest detection limits and a unique design that ensures no cross contamination.
Designed specifically for environmental samples.

How do Seal AQ270 Discrete Analyzers Work?

The SEAL AQ270 uses a robotic sampling arm, and a stepper-motor driven syringe to aspirate, dispense and mix precise quantities of sample and reagent into miniaturised test tubes (reaction wells).
Samples and reagents are incubated in the reaction wells for a pre-programmed time.
A single aliquot is transferred to the stop/ flow optical quality glass cuvette 10mm pathlength. The absorbance is read in the stationary optical bench for the best signal to noise ratio.
Reaction times are programmable from seconds to minutes, with the optimized methods bringing the chemical reaction to full completion and steady state, emulating manual and segmented flow methods.
Once the absorbance is ready, the cuvette is automatically and thoroughly cleaned, eliminating carry over and cross contamination
