Kronos Class B autoclave, 18 litres

A Class B autoclave sterilises everything that passes through a practice: solid and hollow instruments, wrapped or loose, and porous loads such as gauze and fabrics. The fractionated vacuum is what makes this possible: before the steam, air is removed in several stages, so the steam reaches even inside cannulas and into the folds of pouches.

The 18-litre chamber is seamless AISI 304 steel and takes four trays: enough for a day's work in a beauty salon, a podiatry practice or a tattoo studio. The door closes with a motor and stays locked under vacuum until the cycle ends. Every cycle comes out on paper from the built-in printer, ready to file.

Water matters as much as steam: a conductivity meter checks its quality at every load and shows it on the display. With the OSMO3 version the water arrives already purified from a reverse osmosis unit connected to the mains supply, with no canisters to buy and carry; with the internal data logger every cycle is also recorded on a USB stick and archived on the computer.
