SEAL Analytical

The AQ300 Discrete Analyser from SEAL Analytical is a powerful analyser ideal for smaller work loads.

For larger laboratories: AQ400 Discrete Analyser

The AQ300 Discrete Analyser is the latest nutrient analyser from SEAL Analytical.  All the benefits of the larger AQ400 Discrete Analyser are now available to labs with less space or smaller workloads. The AQ300 is designed specifically for environmental samples and incorporates design features that ensure the best reproducibility, the lowest detection limits and a guarantee of no cross contamination, even when ammonia, nitrate with cadmium detection and phenol are run together.

Choose the best Discrete Analyser for your laboratory.

How Does the AQ300 Discrete Analyser Work?

  • A robust sampling arm works in conjunction with a stepper motor-driven syringe that is responsible for aspirating, dispensing and mixing accurate and precise quantities of sample & reagent in miniaturised test tubes (reaction wells).
  • The sample and reagent are incubated in the reaction wells for a pre-programmed time. A single aliquot is transferred into a 10mm, 100% optical glass cuvette, with the absorbance read on the stationary reactant to ensure the best possible signal to noise ratio.
  • A second robotic arm moves reactant/ sample from the reaction wells to the detection area. The sample is always read in the same position in front of the detector, in the same glass cuvette, eliminating issues of scratching and reaction well variability found with direct read systems. As the liquid is moved, not the tray, fewer moving parts means higher reliability.
  • Supplied standard methods have optimised reaction times ensuring the reaction is brought to completion. The complete reaction emulates the manual & segmented flow methods and ensures the lowest detection limits and good reproducibility.
  • After the absorbance is read, the glass cuvetted is thoroughly cleaned and checked ensuring no carry-over or cross contamination.
  • With the patented probe flusher, water from the wash bottle is pumped through the probe flusher as the probe moves up and down through it to clean the outside before dipping in the next liquid.

Seal analytical logoSEAL Analytical Limited is a UK based developer of automated wet chemistry discrete analysers for use in environmental and industrial laboratories.  SEAL has over 25 years experience with automated discrete analysis.  Visit www.seal-analytical.com

In 2002, SEAL formed a wholly owned US subsidiary based in Milwaukee, Wisconsin to promote the sales of wet chemistry discrete analysers in the US and Canada.  Subsequent to this, SEAL's international roll-out continued with distributors being approved in European and Asian Pacific countries.

In 2004, SEAL became the exclusive distributor of Bran+Luebbe Continuous Flow Analysers in the USA, UK and Ireland.

In November 2006, SEAL completed the acquisition of the Bran+Luebbe Continuous Flow Analyser (CFA) and Near InfraRed  (NIR)  Analyser businesses.   This brings together over 50 years of CFA analysis experience of B+L , formally Technicon Industrial Systems, with SEAL's 25 year track record in discrete analysis, allowing SEAL to offer a truly complimentary solution in Automated Chemical Analysis for environmental and industrial laboratories throughout the world.

In August 2008, SEAL joined the Porvair group of companies. Porvair is a specialist filtration and environmental technology group.  This will allow SEAL to continue its dynamic growth  and success worldwide.
