Slimsette™ Tissue and Biopsy Cassettes

made of acetal resin polymer

The Slimsette™ Cassettes, a new generation in the Simport Tissue and Biopsy Cassette family. These cassettes are more compact and efficient than previous cassettes. They feature a unique recessed cover allowing more cassettes to be stacked in automated cassette labeling machines and increasing the number of cassettes that may be stored in storage cabinets.   

Slimsette™ Cassettes are molded from high density acetal resin polymer allowing them to sink rapidly. Acetyl resin polymer is compatible for use with histological reagents and solvents. The covers may be opened and closed repeatedly and always relock securely without specimen loss. The front labeling area has a 45° angle.

Embedding rings are suitable for holding and identifying tissue sample blocks and fit well in microtome chuck adapters. The etched writing surface on the ring is marked with an identification number and placed on top of the sample block. Additional paraffin is poured into the base mold to cement the ring onto the tissue block. The embedding ring securely holds the tissue sample in the microtome chuck adapter for sectioning and then identifies the sample while in storage. Embedding rings are available in white. Sold in boxes of 250 rings; one case is four boxes of 250 rings.
