Glutaraldehydes
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.

  1. Glutaraldehyde, EM Grade, 70

    Polysciences was the first to develop a superior grade of glutaraldehyde suitable for immunochemical techniques.

  2. Glutaraldehyde, Biological Grade, 50% | Polysciences, Inc.

    Biological grade glutaraldehyde has been purified to minimize by-product formation and maximize shelf life. Suitable for most morphological studies.

  3. Glutaraldehyde, EM Grade, 50% | Polysciences, Inc.

    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.

  4. Karnovsky’s Fixative
    Karnovsky’s Fixative
    Catalog Number 22872

    Formaldehyde/Glutaraldehyde fixative commonly used in EM for structural preservation. Pre-measured in ampoules for one-step preparation.

  5. Glutaraldehyde, Biological Grade, 25%

    Biological grade glutaraldehyde has been purified to minimize by-product formation and maximize shelf life. It should be suitable for most morphological studies. For more demanding purity and longer stability use EM grade glutaraldehyde.

  6. Glutaraldehyde, EM Grade, 8% | Polysciences, Inc.

    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.

  7. Glutaraldehyde, EM Grade, 25% | Polysciences, Inc.

    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.

  8. Glutaraldehyde, 8% EM Grade (Glass Distilled)

    EM grade is recommended for histochemical or immunological techniques.
