Radial locking complete Stainless Steel Semi-Automatic with timer and end of cycle Buzzer.


  • MAC Semi Automatic Digital Autoclaves are most ideal for critical applications requiring assured and reliable total destruction of all living micro-organisms.
  • These are semi automatic models requiring tighter control of temperature and sterilizing time, thus eliminating any chances of under or over exposure of media/ samples with respect to temperature and hold time.
  • Inner chamber is made of Stainless Steel (SS-304 grade).
  • Outer body is made of Steel.
  • Heaters cover stand and carrier/bucket are made of Stainless Steel.
  • Lid made of thick machined Stainless Steel plate.
  • Radial locking lid ensures user safety and safe locking.
  • Radial arms are made of mild steel.
  • Rings & legs are made of mild steel.
  • Lid is fitted with Pressure Gauge, Spring Loaded Safety Valve, extra Safety Valve, Manual Exhaust Valve, Vacuum Breaker-cum-Purge Valve as a safety device and water level indicator.
  • Drain Valve facilitates easy cleaning of the chamber.
  • Moulded jointless silicon rubber gasket.
  • All internal joints are argon arc welded, ground and polished to give crevice free internals.
  • µProcessor based Controller with time and temperature settable by user.
  • Operating range from 15 to 22 psi pressure. (adjustable)
  • Class ‘A’ Platinum (Pt-100) sensor, enabling precise and accurate monitoring in 0.1°C resolution and ±1°C accuracy.
  • End of cycle buzzer to alert the user.
  • Miniature Circuit Breaker for MAINS On/Off plus safety of control panel.
  • Industrial grade energy efficient heaters reduce power bills drastically.
  • Fitted with low water cut-off for general safety of heating elements.
  • To work on 220/230Volts, 50/60 Hz AC supply.
