Product Overview:
Like all SEAL discrete analyzers, the AQ400 is designed for environmental laboratories requiring high levels of automation, a wide range of chemistries, limits of detection that ensure compliance with regulatory requirements, and integration with LIMS. As the direct replacement to the renowned AQ2 discrete analyzer, the AQ400 continues the tradition of reliability while offering improved ease-of-maintenance, quieter operation, increased motor precision, higher throughput, and more.
Our flagship discrete analyzer, the AQ400 is designed for mid-sized laboratories looking to increase their testing capacity and throughputs. Leveraging advanced robotics for fast sample preparation, the AQ400 is ideal for applications where multiple varied tests are needed on different samples in a short period of time. This analyzer can also be used as a standalone spectrophotometer.

Highlights of the AQ400
Lower Dection Limit & Higher Reproducibility
An optically pure quartz cuvette provides a 10mm pathlength for maximum sensitivity and lower detection limits. Quartz is superior to styrene for sample analysis, ensuring excellent precision.
Minimal Reagent Usage
SEAL discrete analyzers use just 20 - 400 μL of reagent per test, lowering reagent costs and consumption as well as potential hazardous waste. On-board reagent cooling keeps reagents fresh through long testing periods, and built-in reagent level sensors ensure sufficient volumes for the tests before the run starts. Expiration dates are tracked in the software to remind analysts when it’s time to remake a solution.
Inexpensive Consumables
With detection taking place in a 10 mm flow-through quartz cuvette rather than in reaction wells, consumable costs are significantly lowered as reaction wells are not used in the optical read. Constant heating and a programmable reaction time ensure reactions reach completion before transfer from the reaction well to the cuvette.
Cadmium Reduction for Wider Matrix Compatibility
All SEAL discrete analyzers can run all types of nitrate reduction for colorimetric analysis of nitrate. Our most popular method is cadmium reduction due to the low cost and ability to handle a wide-range of sample types including wastewater, drinking water, industrial, and seawater samples. With cadmium reduction, all hazardous waste is contained in solid form in the cadmium coil for easier, safer disposal, rather than liquid form in other reduction methods. The cadmium coil can be regenerated in-line automatically, saving valuable analyst time.
Eliminate cross-contamination
A feature unique to SEAL discrete analyzers, our probe washer moves with the sample probes wiping the probe clean before moving to a new location, eliminating cross-contamination of samples, reagents, and diluents.
