AQ300 Discrete Analyzer

With the addition of the AQ300 Discrete Analyzer to the SEAL Analytical nutrient analyzer family there is now a nutrient analyzer for every size laboratory and budget. The AQ300 Discrete Analyzer brings all the same benefits as the AQ400 Discrete Analyzer, 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 AQ300 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 even when ammonia, nitrate with cadmium reduction and phenol are run together. Designed specifically for environmental samples, with no compromise.

3. How do Seal AQ300 Discrete Analyzers Work?
The SEAL AQ300 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.
