Space-saving design with lid opening upward.

Programmable auto-start for initiating a cycle up to 1 week later.

Dual-sensing lid interlock prevents lid opening when chamber is pressurized or when temperature

exceeds 97°C.

Automatic air purging by a microprocessor prevents over-pressurization during a cycle.

One-touch lever to easily open and close chamber lid.

Programmable rate of steam exhaust.

Door-closure sensor provides a prompt and the cycle will not start unless the door is closed properly.

In-process display shows status and progress of sterilization cycle.

Agar sterilization mode for sterilizing agar and then automatically maintaining it at liquid temperature.

Unique accessory: Floating sensor to monitor load temperature.

Sterilization timer is activated only when load temperature reaches set temperature.

Agar melting mode for rapidly melting agar and maintaining it at liquid temperature, or for a hot and faster


Memory backup system retains user-programmed parameters even in case of power failure.

1. For agar

Heating -> Sterilization -> Exhaust (from no exhaust to slow, programmable) -> Warming -> Completion

2. For liquids

Heating -> Sterilization -> Exhaust (from no exhaust to slow, programmable) -> Completion

3. For solids

Heating -> Sterilization -> Exhaust (fast, default) -> Completion

4. For melting agar or for faster start-up

Rapid melting at 60°C to 100°C (temperature and time programmable) -> Maintain at 45°C to 60°C (temperature programmable) -> Completion
