EM grade is recommended for histochemical or immunological techniques.
Polysciences was the first to develop a superior grade of glutaraldehyde suitable for immunochemical techniques. Each batch of vacuum distilled glutaraldehyde manufactured by Polysciences is analyzed to maintain consistent high quality and freedom from contaminants which destroy antigenicity.
Each ampoule is fitted with an ampoule cracker for added safety.
Polysciences offers highly purified 8%, 25%, 50%, 70% EM Gradeglutaraldehyde solutions that are free of contaminants. Studies have shown that Polysciences’clear, colorless, EM grade glutaraldehydes are practically free of undesirable polymeric product impurities.1-3.
