The Heidolph Tuttnauer 2540M autoclave (model HEI-023210304) is a 23 L/6 gallon analog sterilizer with a 10 x 18” (diameter x depth) chamber, four stainless steel trays, and a 120V power source. Temperature settings are selectable from 100 to 134 degrees C (212 to 273 F) with sterilization times up to 60 minutes for simplified operations. The autoclave comes with four stainless steel trays for maximizing space in the chamber by holding instruments, liquids, laboratory equipment and other items to be sterilized.
The autoclave has a combination pressure and temperature gauge, and an automatic low water shut off to prevent damage to the heating elements if there is insufficient water for sterilization. A heat-insulated, double-locking door helps protect users from accidental burns and prevents the chamber from being opened during the sterilization cycle. The autoclave has a fast or slow exhaust selection, with the fast exhaust for quickly drying solids, and the slow exhaust for preventing media and liquid boil-over. A closed-door drying cycle maintains sterility and removes extra moisture after sterilization. A continuous pressure purge removes air pockets and ensures even sterilization, and a 3L water reservoir prevents frequent refills (with the drain located on top for simplified cleaning). The autoclave also has an automatic shut-off for conserving energy.
The American Society of Mechanical Engineers (ASME)-stamped 316 L stainless steel chamber capacity is 23 L/6 gallons and its dimensions are 25.4 x 45.7 cm (10 x 18 inches) (diameter x depth); tray dimensions are 17 x 41.5 x 2 cm (6.7 x 16.3 x 0.8 inches); exterior dimensions are 38.1 x 50.8 x 50.8 cm (15 x 20 x 20 inches) (H x W x D ), and it weighs 48 kg (106 lb). (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) Electrical: 120V, 1,400W, and the current is 12A.
Autoclaves are ovens that sterilize laboratory instruments and can kill bacteria, viruses or both. They are often used in laboratories to sterilize lab equipment, media and liquids, and can be designed to meet different health, safety, and environmental standards.
