SEAL Analyzers and Sample Preparation Systems

QuAAtro 39

The QuAAtro39 high performance microflow chemistry analyzer is ideal for the detection of ultra-low nutrients in water, wastewater, seawater, soil, plant extracts, tobacco and wine, utilizing USEPA, ISO and ASTM standard methods.

The SEAL AA100 Auto Analyzer

The compact dual channel AA100 AutoAnalyzer is the ideal chemical analyzer for laboratories running only 1 or 2 dedicated chemistries. Like the bigger AA500 AutoAnalyzer it is designed specifically for environmental and industrial testing laboratories, utilizing USEPA, ISO and ASTM standard methods.

AQ400 Discrete Analyzer

The SEAL AQ400 Discrete Analyzer is a bench-top analyzer designed by chemists to address the needs of environmental laboratories requiring high levels of automation, a wide range of chemistries and limits of detection that ensure compliance with regulatory requirements.

SmartBlock ll - Graphite Heating Block

The SmartBlock ll is a graphite heating block that can simultaneously digest up to 60 samples. Faster, simpler and safer than digestions carried out using traditional laboratory equipment, the robust construction, small footprint and economical pricing makes it ideal for small laboratories or those with limited space looking for simpler and safer Metals digestions.

AQ300 Discrete Analyzer

The AQ300 Discrete Analyzer brings all the same benefits as the AQ400 Discrete Analyzer, but with a smaller footprint and lower sample throughput, Making it ideal for laboratories with less space or smaller workload all while utilizing USEPA, ISO and ASTM standard methods.

BD50 / BD28 Block Digestion System

The SEAL Analytical Digestion Block is a Kjeldahl digestion system that automates acid digestions of up to 50 laboratory samples simultaneously. It is ideal for Total Nitrogen (TKN) and Phosphorous (TP) digestion.

Minilab 1200 BOD System

Automating BOD. Cost effective solution for automating Biological Oxygen Demand


The DEENA II is an automated metals and mercury digestion system that fully automates the digestion process, including dispensing reagents, heating and cooling. DEENA II has the necessary functionality to automate your standard sample digestion process without modification.

The SEAL AA500 Segmented Flow Analyzer

The AA500 is the AutoAnalyzer you’ve been waiting for- total automation, ultralow detection, multitest chemistries, high throughput

SEAL Acquires Rohasys Lab Automation

SEAL Analytical has acquired ROHASYS BV, a Dutch manufacturer of laboratory products for automating and robotising sample (pre) treatment. “This new partnership creates exciting opportunities for both companies,” says SEAL President Stuart Smith.

SEAL Press Release

The UK’s National Oceanography Centre’s (NOC) ocean-going lab is the real test of a nutrient analyzer. The NOC undertakes integrated ocean research and technology development from the coast to the deep ocean and has a heavy requirement for seawater analysis in their facilities and on board research vessels. Under these conditions, high levels of precision and reliability can be a challenge for most laboratory equipment, so NOC has invested in SEAL Analytical segmented flow analyzers (SFAs) - the AA3 and the QuAAtro.
