Specification :

Automatic lid opening button replaces a foot pedal.
Automatic lid closing button closes and locks lid conveniently and safely.
New body design with a 50- or 80-liter chamber of larger diameter and shorter height.
Safety interlock senses pressure and temperature and prevents lid from opening when the chamber is
pressurized, temperature is too high, and also during a cycle.
Programmable auto-start for running a cycle up to 99 hours later.
Efficient 15-liter steam condenser eliminates steam exhaust into the lab.
Over-flow lamp indicates that the drain bottle is full and ready to be emptied.
Built-in cooling fan for faster post-sterilization cooling and shorter completion time.
Selectable rate of steam venting after sterilization.
Programmable time for air removal before sterilization.
Large control and display panel improves functionality and shows the progress of the sterilization cycle:
