Over 50 Years Experience

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. This experience continues to drive SEAL's development of flow techniques and automated lab analyzers for environmental and industrial laboratories.
