The Heidolph Tuttnauer autoclave is an analog sterilizer available in several different capacities, with a 120 or 220V power source, and steel trays for maximizing space in the chamber. The temperature settings are selectable from 100 to 134 degrees C (212 to 273 degrees F), with sterilization times up to 60 minutes for simplified operations.
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 fast or slow exhaust selections, with fast exhaust for quickly drying solids, and slow exhaust for preventing media and liquid boil over. A closed-door drying cycle maintains sterility and removes extra moisture after sterilization. Continuous pressure purge removes air pockets and ensures even sterilization. A large, 3-liter water reservoir reduces refills, and is configured with the drain on top to simplify cleaning. The autoclave also automatic shuts off for energy savings.
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.
