large sterilization cassette

The Large Sterilization Cassette (Article# LS9-499) is a 12-instrument dental micro surgery tray built from medical-grade 304 stainless steel. The frame construction consists of a fully perforated upper lid and a slotted base panel — both machined with rectangular and diamond-pattern openings that allow unrestricted steam circulation through every surface during autoclave cycles. The overall footprint accommodates 12 full-length microsurgical instruments laid in parallel rows. Two side-mounted locking buttons secure the lid firmly shut, preventing the cassette from opening under autoclave vibration. Twelve red medical-grade silicone color-coding pins are seated along two rows on the upper lid, functioning as instrument identification markers and secondary tip protectors.

The instrument-holding base carries parallel longitudinal slots that keep each instrument aligned and separated throughout the sterilization cycle. This slot-and-pin system prevents instrument-to-instrument contact, reducing edge damage during autoclaving and transport. The silicone pins are heat-resistant and remain stable through repeated steam sterilization at 134°C. The cassette is compatible with both gravity-displacement and pre-vacuum autoclave systems. This Sterilization Cassette Large format is sold as Article# LS9-499, pre-matched to the Dental Micro Surgery Set of 12 Pieces.

Dental clinics and oral surgery practices use this type of Large Sterilization Cassette to manage complete microsurgical instrument sets as a single, contained unit — from pre-procedure ultrasonic cleaning through sterilization to chairside delivery. Periodontists and implant surgeons rely on tray-based sterilization cassettes to maintain instrument accountability, reduce cross-contamination risk, and cut individual wrapping time between surgical appointments.

Leader Surgical packages this cassette as a bundled solution with its 12-piece microsurgery set, giving surgical practices a fully coordinated, infection-control-compliant system right out of the box.

How many instruments can a large cassette hold?
Standard large cassettes are typically designed to hold 10 to 20 instruments. For example, the Hu-Friedy Large Signature Series™ 20 Instrument Cassette (203 x 280 x 32 mm) is a common benchmark for surgical and implantology sets.
