Simport biopsy foam pads are used to hold biopsies in place and prevent them from being lost during processing. The specially formulated foam is always verified for consistency to achieve optimum solvent flow. Biopsy samples are sandwiched between two foam pads and are placed either in tissue capsules or cassettes with metal or plastic lids. Model M476-4 is for use with the Micromesh™ and Slimsette™ Cassettes. Will resist temperatures from -40°C to 121°C.
