BioClave™ Mini Research Autoclave, 8 liter, 115V, Cat. No.: BM-B4000-M, Despite the space-saving exterior dimensions, the stainless steel sterilization chambers are surprisingly large, accommodating a variety of liquids, media, instruments, glassware, plasticware and other common laboratory items. Both models include a mechanical and electrical safety interlock that prevents the door from being opened until the pressure has reached zero PSI. Three trays (2 with the BioClave Min) are supplied with each unit, along with a convenient tray removal tool.
