Tissue Grinders 35mL – freestanding. With these closed tissue grinder systems, you seal before grinding to minimize sample contact through aspirations and overflow. The abrasive surface is molded-in, so there’s no sandy sediment to obscure the sample. Systems include polypropylene tube, high-impact polystyrene pestle and tip and an antiroll HDPE cap. Supplied assembled and sterile. Extra cap and patient identification label included for storage, transport and traceability. Easy-open Tyvek® package. UOM: 10/CS.
