The Benchmark Scientific B-1000-E BactiZapper has an asbestos-free core element that uses infrared heating to produce 815°C (1500°F). It completely sterilizes in 5-7 seconds. The BactiZapper uses well-proven technology to provide instant sterilization of platinum inoculating loops, needles, glass tube/pipette mouths and various metal & borosilicate glass instruments used in quality control and research. It also has a lower temperature setting (500°C) that can be used as a "standby" and extends usable life.The ceramic heating element is safely enclosed in a perforated stainless steel guard chamber, protecting users from accidental contact with the extreme temperatures of the core area. It is extremely compact, convenient and can be used in anaerobic and aerobic chambers.
