Standard Operating Features

  • Self-contained design eliminates external plumbing and hardwiring for easy installation
  • Simple operation
  • ASME-stamped, Type 316 L stainless-steel chamber ensures long-lasting reliability, durability, and high-corrosion resistance
  • Fast/slow exhause (fast allows quick cycle time of solids while slow exhause prevents media and liquid boil-over)
  • Closed-door drying system maintains sterility
  • Drying cycle removes residual moisture after sterilization
  • Continuous pressure purge eliminates air pockets and ensures thorough, even sterilization
  • Large-capacity reservoir provides ample water supply to avoid frequent fill-ups
  • Water drain is conveniently located on top to allow quick and easy cleaning of reservoir
  • Automatic shut-off feature saves energy

Standard Safety Features
  • Heat-insulated, double-locking door protects against accidental burns
  • Door cannot be opened while chamber is under pressure
  • Automatic low water level shut-off prevents damage to the heater elements if there is insufficient water for the sterilization cycyle
  • Overtemperature cutoff and overpressure valve ensure safe operation

Automated Electronic Sterilizers
Electronic models use microprocessor controls to completely automate every stage of the cycle - water filling, heating, sterilization, exhaust and drying
Features of all automated electronic sterilizers

  • Sterilization time to 59 minutes
  • Temperature selection from 105° to 137°C (221° to 279°F)
  • In-line particle filter to protect valves
  • Electronic pressure and temperature sensors
  • Low-water alarm (sounds when reservoir needs to be refilled)
  • Standby heating keeps chamber warm for quicker cycles
EP Models
Helps meet GLP documentation requirements. Additional features include:
  • Built-in printer that provides a printed summary at the end of each cycle
  • Documents temperature, elapsed drying and sterilization time, selected cycle, cycle number, real time and date, errors or interruptions
  • Available with 9-, 10-, 12- and 15-inch diameter chambers
EA Models
Ideal for sterilizing wrapped and sealed instruments. Additional features include:
  • Fully automatic autoclaves are specially designed with preloaded cycles for sterilizing packs, pouches, sealed pipette racks, unwrapped instruments and other contained/wrapped materials
  • Highly efficient air-driven pump circulates hot air after the sterilization cycle to ensure thorough drying of samples and to reduce overall drying time
  • Available with 9-, 10- and 15-inch diameter chambers, with and without a built-in printer
Kwiklave Model 2540EAKP
  • Cuts sterilization time in half–perfect for fast instrument turnaround. Offers all standard operating and safety features, plus a special quick cycle
  • Advanced heating element reduces the time needed for the autoclave to reach optimal sterilization temperature, reducing overall sterilization time by up to 50%
  • Has a 10-inch diameter chamber and comes equipped with a built-in printer to document results
