Dental practices, GP minor surgery rooms, and podiatry clinics keep the HS-IC twin-hoop rack in the chamber as the frame for their trays. Veterinary practices and tattoo or piercing studios use it the same way. Trays go in and out with each load while the rack stays put, so it only leaves the chamber when you clean it or replace he rack
Replacement is where its simplicity counts. A bent or missing rack leaves trays without proper support, and this one goes into the chamber in a single movement, with no tools, screws, or adjustment. Cleaning works the same way: once the chamber has cooled, the rack lifts out by hand, the chamber gets its clean, and the frame drops back into place before the next load.
During a cycle, the open wire frame lets steam reach the trays from above, below and every side. Loading still decides how well the load sterilises and dries. Hence, instruments lie side by side in one layer with hinges open, pouches lie flat without overlapping, and each tray stays within the steriliser's per-tray load limit.
Its hoops follow one round chamber, tying it to the steriliser it was made for, and chambers of a different diameter or depth take their own rack. Trays are separate items, and so are tray handles. Square or rectangular chambers don't use round hoops, and upright pouches need a pouch rack.
