Polysciences pioneered the supply of redistilled high purity glutaraldehydes, making them the standard for discriminating researchers.
Biological Grade glutaraldehyde is available in 25% and 50% solutions, also purified to minimize by-product formation and maximize shelf life, suitable for most morphological studies and routine work. For additional information, please see Technical Data Sheet #124.
EM Grade glutaraldehyde is available in 8%, 25%, 50% and 70% solutions, recommended for histological or immunological techniques demanding purity and longer stability. Our EM Grade glutaraldehyde is vacuum distilled, and free of contaminants.
