PST® Plastic Instrument Sterilization Tray features a unique grid system, making it easy to install mats or inserts for surgical instrument protection. Integral feet on base and corner ridges of lid allow for easier handling in autoclaves and storage. See-through lid provides easy identification while offering protection during transport. Mats come with each tray to prevent shifting of instruments, and retain their flexibility even after repeated sterilization at high temperatures. All trays are molded from GE's ULTEM® resin using mold flow analysis to guarantee product strength, structural integrity, and extended life cycle, and withstands the rigors of standard sterilization methods, including steam autoclave, dry heat, or chemical. Trays include base, lid, and mat and are available in Narrow, Standard, or Wide models with various sizes to accommodate a variety of instruments.
