The Heidolph Tuttnauer autoclave is an electric air-driven sterilizer available in several different capacities, with a 120 or 220V power source, an air-driven pump option, steel trays for maximizing space in the chamber, and a printer option. The autoclave has four adjustable programs with temperature selections from 105 to 137 degrees C (221 to 279 degrees F) with sterilization times up to 59 minutes for simplified and reproducible operations. Stainless steel trays maximize space in the chamber by holding instruments, liquids, laboratory equipment, and other items to be sterilized. After the sterilization cycle is complete, the air-driven pump model circulates hot air to ensure thorough drying and to reduce drying time. An option is also available which includes a printer for documenting Good Laboratory Practices (GLP).
A digital display continuously shows temperature, pressure, and running time. All cycle stages are automatic and microprocessor-controlled, from water-fill, to sterilization, exhaust, and drying. The autoclave has a low water alarm for notifying users when the reservoir needs to be refilled, an in-line particle filter to protect valves, and a standby heating function to keep the chamber warm between cycles. The autoclave also has a combination pressure and temperature gauge, and an automatic low water shutoff prevents 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 also prevents the chamber from being opened during the sterilization cycle. The autoclave has fast or slow exhaust selections. Fast exhaust quickly dries solids, and slow exhaust prevents 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, and a reservoir with the drain located on top simplifies cleaning. The autoclave automatically shuts off for energy savings, and a battery backup ensures that controls retain their settings in the event of power failure.
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.
