Kidney dishes in a variety of sizes and materials. There are stainless steel kidney dishes in 15cm, 20cm, and 25cm options alongside a plastic 20cm kidney bowl. These dishes are all suitable for being sterilized in an autoclave machine. They are usually accompanied by a stainless steel instrument tray to keep all your equipment in a thoroughly sterile environment. https://new-medinstruments.com/kidney-dish-stainless-steel.html
