EM grade is recommended for histochemical or immunological techniques.

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

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

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

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.
