SEAL Analytical has over 50 years experience in environmental and industrial automated analyzers. SEAL purchased Bran+Luebbe, who earlier purchased Technicon Corporation, the first to commercialise Continuous Flow Analysis. Technicon's AutoAnalyzer became the best-known and most successful Continuous Flow Analyzer in the world, and the instrument that most EPA methods for automated colorimetric analysis were written on and continue to reference.
