cassette partition racks (11 and 16pcs)

The Cassette Partition Racks (11 and 16pcs) are T-profile wire frame dividers built to organize instruments inside sterilization cassette trays. The LS11-311 variant holds 16 pieces and is formed from medical-grade stainless steel wire, delivering high structural rigidity through repeated steam sterilization cycles at 134°C without bending or corrosion. The LS11-312 A holds 11 pieces and uses lightweight aluminium construction, making it the preferred choice where total cassette weight needs to stay low. Both variants feature a broad central spine with outward-angled side arms and a serrated lower edge — the toothed profile locks each instrument shank firmly in its own bay and prevents lateral drift during handling and autoclaving.

The T-frame geometry creates wider instrument bays compared to standard U-profile partitions, accommodating bulkier instrument handles such as mirror handles, syringe bodies, and larger scalers without crowding. The open wire construction throughout the frame keeps steam circulation fully unrestricted, so every instrument surface receives direct sterilant contact during the autoclave cycle. The angled side arms hook over the internal cassette rails, holding the entire Cassette Rack assembly flat and stable without any fasteners or adhesives.

Dental hygienists and oral surgeons use the Cassette Partition Racks (11 and 16pcs) inside Dental Cassette Instruments trays to organize examination mirrors, probes, curettes, and composite placement instruments before autoclave runs. The 16-piece stainless steel variant suits busy periodontal and restorative dental setups running full instrument sets, while the 11-piece aluminium variant fits lighter cassette configurations used in minor procedure rooms and specialist clinics.

Leader Surgical produces both variants with consistent frame tolerances and surface finishes — ensuring each partition seats correctly into standard cassette rails and holds instrument position reliably through the full sterilization and storage cycle.

What are cassettes in dentistry?
Dental cassettes, also known as instrument or hygiene cassettes are rectangular storage boxes made from stainless steel, aluminum or plastic. Cassette interiors feature holding slots for dental instruments, and the exteriors are perforated with openings to allow for sterilization access.
