These highly flexible blue foam pads are ideally suited to the processing of biopsy specimens in standard cassettes. The foam has a fully open structure (90% void space) allowing complete circulation of processing reagents when used in a sandwich technique for small or fragmented biopsies. Foam sponge is very useful for small specimens in biopsy tests. Fits standard cassettes. Avoids sample loss through drain holes when the sample is processed.
Does not affect paraffin drainage.
