    1.Generals Introduction Model 3870 ELCPVG is a laboratory sterilizer designed especially for the sterilization of instruments, liquids, and other materials in hospital laboratories, medical laboratories, research institutes, food laboratories and pharmaceutical facilities. Special feature of ELCPV-D model is the vacuum pump that enables air removal prior to sterilization and during the drying stage.
  • Page 7 A computerized control unit ensuring a fully automatic sterilization cycle controls the autoclave. The temperature and pressure are controlled through sensors placed inside and outside the media container or bottles. The sterilizer is fully automatic with a choice of 10 programs, eliminating any need for operator intervention during a cycle (programs 9-10 are for vacuum test only).
