Auto Analyzer 3HR (AA3HR)

The AA3 HR's high resolution digital photometer, with optimized optics and 24-bit resolution, provides high sensitivity at ultra-low concentrations, wider dynamic ranges and lower detection limits. Air bubbles pass through the flow cell without affecting the signal, increasing sampling rate. LED light sources are available for high performance applications, such as use on research vessels. Other detectors, such as flame photometer and UV spectrophotometer are available for special applications.

The chemistry manifold is comprised of close-tolerance glass components, which are chemically inert and allow for easy visual check of operation. Multi-test manifolds are available, where different analyses can be run - with no hardware or pump tube changes. Complex procedures, such as distillation, dialysis and UV digestion, can also be incorporated.

High precision multi-speed peristaltic pumps ensure regular, reproducible dosing of liquid. High speed is available for fast start-up and wash-out and low speed is available to conserve reagents following a run. Electronically controlled air valves provide precise air bubble injection.

The AA3 HR's random access autosamplers are fast, robust and have various rack sizes to meet your sample requirements. Samples can be added at any time during the run. Instrument control and data acquisition is carried out through the intuitive, easy to use AACE software package. AACE is LIMS compatible and both standard and GLP versions are available.

SEAL has more than 1,000 documented methods and new applications are regularly being developed in our laboratories. USEPA, ASTM, ISO, AOAC, DIN, CORESTA and other international regulatory compliant methods are available.
