The world's most successful segmented flow analyzer
Ultra-low Detection Limits · Highly Reproducible · Robust and Reliable · Modular and Flexible
Building on the success of the Technicon™ / Bran Luebbe™ AutoAnalyzer II and maintaining its reputation of high quality - Every part of the AutoAnalyzer 3 incorporates improvements enabled by modern electronics and mechanical technology to bring your laboratory higher performance and lower costs.
Segmented Flow Analysis
The SEAL AutoAnalyzer 3 uses all the advantages of air-segmented flow. With reaction times up to 30 minutes, even complex procedures like distillation can be automated.
Dialyzers can be built into the system for elimination of interference from dirty or colored samples. Our proprietary in-line UV digestion procedure conforms to the ISO Standard Methods for automated measurement of Total Cyanide and Total Phosphorus.
Modular Design for high flexibility
A one channel SEAL AutoAnalyzer 3 System comprises a Sampler, Pump, Chemical Manifold, Detector and Computer. The system can easily be extended by adding a second Chemical Manifold and a second Detector.
The SEAL AutoAnalyzer then becomes a Two Channel System, which measures two different analytes at the same time. Additional Detectors and Manifolds can be added, as required, up to a total of 8 channels.

Segmented Flow Advantages
Fully Automatic Operation - Start up to Shut down
Ultra Low Detection Limits
40 to 100 samples per hour
over 700 documented applications
Low reagent consumption
Compatible with Technicon and Bran+Luebbe AutoAnalyzer II Systems
Quick Method Change-over
Wide range: dilution of sample is rarely necessary
Dual Range Methods
Most multitest methods are also dual-range; with separate pump tubes for high and low ranges. You can test an extremely wide range of sample concentrations.
For example, the AutoAnalyzer 3 method for Nitrate in Seawater can measure up to 8500 ug N/L and has a detection limit of 0.14 ug/L. This same manifold can be used to measure Ammonia and Silicate.
Compact in size. Plug and Start with limited tubing. Pump, Manifold and Detector all in a bench sized Analyzer.
High Performance Digital Photometer
The AA1 digital photometer provides high sensitivity, wide dynamic ranges and low detection limits. LED light sources are used.
Small Footprint
The NEW AA1 is light and compact and will easily fit on any standard benchtop.
New Carousel Sampler
The NEW AA1 Carousel Sampler is Simple, yet Robust and EASY to use. The AA1 Carousel Sampler is compact and light, fitting easily onto any standard benchtop!
AACE lite for Windows
Instrument control and data acquisition is carried out through the intuitive, easy to use AACE lite software package. SEAL AACE Software makes daily operation quicker and easier.
A new low cost flexible analyzer that uses the principle of Discrete Analysis. Each test occurs in a separate or discrete reaction vessel.
It is ideal for laboratories with smaller workloads requiring varied tests on different samples and when individual tests are needed immediately.
How does the NEW AQ1 Work?
The AQ1 employs a robust robotic sampling arm working in conjunction with a stepper motor-driven syringe. The syringe is used for aspirating, dispensing and mixing accurate and precise quantities of sample and reagent into miniaturized test tubes, called reaction wells.
The Sample and reagents are incubated in the reaction wells for a pre-programmed time. A single aliquot is then transferred into the stop/flow Optical Quality Glass Cuvette. The absorbance of the reaction is read in our stationary optical bench to assure the best possible signal to noise ratio.
Programmable Reaction Times
The reaction times are user programmable from seconds to minutes. We have optimized the SEAL AQ1 Methods to ensure that the chemical reaction is brought to full completion and steady state. This completed reaction exactly emulates both the Manual and the Segmented Flow Methods.
By allowing the chemical reaction to come to a full steady state, we maximise sensitivity and results are less sensitive to reaction changes. Once the absorbance is read, the cuvette is thoroughly cleaned, eliminating any carry over or cross contamination.
