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.
