A Discrete Analyzer uses a robotic sampling arm with a syringe to aspirate, dispense and
mix precise quantities of sample and reagent into miniaturized test tubes (reaction wells).
Samples and reagents are incubated in the reaction wells for a pre-programmed time, allowing
the color reaction to complete.
Before dipping in the next liquid, the probe is thoroughly cleaned to avoid contamination and carry-over. Water is pumped through the probe washer as the probe moves up and down through it to clean the outside.
A single aliquot is transferred to the stop/ flow Optical Quality Glass Cuvette, where the absorbance is read in the stationary optical bench for the best signal to noise ratio. As the liquid is moved, not the tray, fewer moving parts means higher reliability. Once the absorbance is ready, the cuvette is automatically and thoroughly cleaned, eliminating carry over or cross contamination.
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, ensuring the lowest detection limits & good reproducibility.
By using different programs and reagents, multiple analytes can be determined in the same instrument. For each sample, the required tests can be selected individually. Flexibility and ease-of-used are increased by automatic pre-dilution and post-dilution of off-scale samples.
This compact, bench-top analyzer completely automates sample testing in laboratories requiring many and varied tests on different samples and/or individual results needed in a short time. Unlike many Discrete Analyzers the SEAL AQ2 has been designed specifically for testing environmental samples, including water, soil and plant extracts. For environmental laboratories considering updating or purchasing new laboratory testing equipment the AQ2 Discrete Analyzer will give you the best analysis and eliminate problems inherent in analyzers designed for clinical use.View Brochure
With the addition of the AQ1 Discrete Analyzer to the SEAL Analytical nutrient analyzer family there is now a nutrient analyzer for every size laboratory and budget.

The compact dual channel AA1 auto analyzer is the ideal chemical analyzer for laboratories
running only 1 or 2 dedicated chemistries.
Like the bigger AA3 HR AutoAnalyzer it is designed specifically for environmental and
industrial testing laboratories.
Using Segmented Flow Analysis techniques (also known as Continuous Flow Analysis)
the AA1 AutoAnalyzer fully automates repetitive and complex sample analysis steps,
including sample distillation.
With its very small footprint, this compact auto analyzer will fit into any bench top,
in any orientation. Despite its compact size and simplicity of use, the AA1 AutoAnalyzer

Digestion Block Model Options
DEENA II is an automated digestion system that fully automates the dispensing
of reagents into test tubes, as well as the heating and cooling steps in the digestion process.
In metal and mercury analysis, manual sample preparation often consists of many steps that are
labor intensive and time consuming.
DEENA II alleviates most of the manual sample preparation and reduces the errors associated with sample handling. DEENA II has the necessary functionality to automate your sample digestion process without modifying it. DEENA II can also run unattended overnight, so your samples are ready for analysis when you arrive in the morning.
In addition to dispensing reagents and heating the samples, DEENA II prepares calibration and spike standards, shakes the samples, inspects their color, adjusts the sample volumes after the digestion process, and records every step taken in the process.
DEENA II handles up to six standards and nine reagents, including a dedicated reagent line for difficult solutions (like KMnO4), avoiding cross-contamination.
There are also three racks, each having a capacity of 20 samples, for ease of handling and portability.
With the optional fume hood, DEENA II can be placed on a bench top, freeing up valuable fume hood space.
DEENA II is ideal for:
For laboratories that dispense their acids manually, we offer our superior manual hot block.
The digestion block is acid resistant, and provides a steady temperature by heating the bottom
and the sides of each vessel.
Our standard block is made for flat bottomed vials, but we have blocks for conical bottomed vessels readily available. The standard SmartBlock is 60 position for 50ml tubes.
