SEAL Analytical GmbH

A World Leader in Analysers for Environmental & Industrial Applications


SEAL Analytical, a Porvair company brand, is a world leader in the design, development, and manufacture of Automation, including Discrete Analysers, Continuous Segmented Flow Analysers, Robotics and Pre-Sample treatment equipment. SEAL’s instruments are specifically designed and optimised for use with environmental samples. SEAL analysers are also widely acknowledged as the best-in-class and instrument of choice for monitoring nutrients in water & wastewater, seawater, soils & plant tissue, as well as the quality control of industrial products, fertilizers and tobacco.

SEAL’s Ingenuity Solves Common Lab Problems. For over 50 years SEAL Analytical has provided alternatives to the laboratory tasks consuming the largest share of a technician’s task time. SEAL’s Automation solutions helps you with sample testing, pre-treatment, sub-sampling as well as colorimetric analysis with choice to suit your workload, lab space and budget.

Automation. SEAL Analytical’s advanced automation includes a robotic platform for every size laboratory and workload. Tedious, repetitive and time consuming processes such as BOD, COD, alkalinity, pH and conductivity testing are easily automated and is fully customisable ensuring regulations can be met.

Colorimetric Analysis. SEAL analysers automate your wet chemistry methods. Since analysing environmental and water samples is more demanding than analysing other sample types, SEALs priority is on very low detection levels, precision and reproducible results. All SEAL analysers incorporate automation to make your lab more efficient. Discrete Analysers are ideal for many and varied tests on different samples. Continuous Segmented Flow Analysers are available for when a larger number of samples are to be analysed and/or more sample treatment is required such as distillation, UV digestion or gas diffusion for analytes such as cyanide, phenol, Total phosphorous and Nitrogen.

Sample Pre-Treatment. SEAL sample pre-treatment options achieve sample digestion in an accurate, fast, uncomplicated, cost effective and highly reproducible manner. Digestions become more reproducible, efficient and environmentally friendly with laboratory safety significantly improved, even when dealing with difficult environmental matrices such as soil and sludge materials. Replacing manual sample digests with SEAL robotic options significantly increase laboratory throughput and profitability.

Over 50 Years’ Experience. SEAL Analytical has over 50 years’ experience in environmental and industrial automated analysers. SEAL acquired Bran+Luebbe analytics, who were Technicon Corporation, the first to commercialise Continuous Flow Analysis. Technicon's AutoAnalyserII became the best-known and most successful Continuous Flow Analyser in the world, and the instrument that most EPA methods for automated colorimetric analysis were written on and continue to reference. This experience continues to drive SEAL's development of automated lab analysers for environmental and industrial laboratories.

Worldwide. With full teams of engineering and chemistry staff in global facilities in Europe, USA and China, laboratories can be sure of the best support, instruments and methods, meeting the latest regulatory requirements. The global facilities are well supported by a worldwide network of specialist distributors and sales & service centers. Our specialist distributors maintain local stocks of SEAL Analytical parts and have factory trained service staff.

Approved Environmental Methods. SEAL understands the importance of Governmental approved methods in the Environmental Sector. We work closely with the USEPA, ISO, SEPA and the UKAS and have obtained written approval for both Continuous Segmented Flow Analyser and Discrete Analyser methods.

In-House Technical Experts. The depth of knowledge in SEAL Analytical in-house Technical Team of chemists, engineers and software programmers sets us apart from all others in the industry. Our team is available to support all your chemistry, hardware and software needs.
