Despite the space-saving exterior dimensions of the B4000-M-E BioClave Mini Research Autoclave, the stainless steel chambers are surprisingly large, accommodating a variety of liquids, media, instruments, glassware, plasticware and other common laboratory items. The B4000 M E include a mechanical and electrical safety interlock that prevents the door from being opened until the pressure has reached zero PSI. With large digital displays and fully automatic operation, all segments of the cycle (fill, sterilize, exhaust and dry) commence and run to completion by simply pressing the start button. The 8 liter BioClave Mini AutoClave Oven is preprogrammed to meet basic sterilization needs. Although the temperature can be selected at either 121°C or 134°C, the sterilization time is fixed. The economical BioClave Mini is the ideal choice wherever benchtop sterilization is required and space is limited.
