The MLV laboratory line of vertical steam sterilizers from Tuttnauer are vertical, semi-automatic, and controlled electro-mechanically. They likewise offer safe, affordable, and efficient sterilization. The semi-automatic labora is used to sterilize liquids like buffer solution and nutrient media. Solid materials like tubes and filters, glassware, and plastic items can also be sterilized. As for safety, its autoclave lids have several safety features, both digital and mechanical. It has a safety device that does not allow the operator to open the door if the chamber is filled with pressure. Also, the door will remain lock until the time that the pressure inside the chamber is the same with room pressure. Safety valves are found on the chamber. Should the pressure go over the limit, the safety valves will immediately discharge. The chamber is made of 316Ti-grade stainless steel and offers excellent resistance to corrosion. The autoclave's design gives access to all components and makes it easy to maintain. There is cold tap water in the exhaust drain so that the exhaust's temperature is cooled before it even reaches the drain.
