Saving the installation space

The main body is very compact owing to the design which provides thorough installation space saving. In addition, installation space at the side of the main body which is required for models employing a slide-open lid, which is not necessary at SX autoclaves top-open lid. Even when several SX autoclaves are installed side-by-side, the necessary installation space is minimized.

Easily viewable “work monitor”

The LED display shows working status for easy monitoring. The process being performed is indicated by an LED indication lamp blinking in red.

The illuminated display on the operating panel shown in the picture is different from the actual display at the time of operation.

Cooling fan provided as a standard feature

A rapid air-cooling function (vessel-cooling fan) permitting reduction of chamber cool down time is provided as a standard feature. This is most appropriate for lowering the temperature rapidly on completion of the cycle. The time required for lower the temperature is much reduced by employment of the cooling fan in comparison with natural cooling.

Sterilizing course selection

The optimal sterilizing course can be selected from among five courses, such as the liquid sterilizing course in addition to that for normal sterilization.


Other features

Large indication lamp “Operated”

An easily viewable large indication “Operated” is provided at the upper section of the operating panel.
Depending on the pressure status (normal pressure/pressure is applied),the displayed color changes.

Setting to 100°C is possible.

Variable temperature setting such as to 100°C as well as to 121°C has been made possible.The temperature can be set within the range from 45°C to 135°C in steps of one degree (heating mode up to 104°C).

Auto-variable exhaust speed

A function allowing the exhaust valve to open automatically after completion of sterilization is provided. The exhaust speed can be set to one of six levels (set to variable for liquid sterilization)

Timer function

The operation starting time can be preset easily. By presetting the start of operation, otherwise wasted periods at night or early morning, can be used effectively.

Setting to 100°C is possible.4

Variable temperature setting such as to 100°C as well as to 121°C has been made possible.The temperature can be set within the range from 45°C to 135°C in steps of one degree (heating mode up to 104°C).

Lid interlock

A safety device (lid interlock mechanism) for locking the lid during operation is provided. A high level of safety is assured to prevent unanticipated accidents.

Pressure fine adjustment function

When the balance between the temperature and pressure deviates during sterilization, fine exhausting is carried out automatically in order to adjust the best chamber condition.

Reliable & Speedy Sterilization

A top-open lid, which can be operated easily with a single hand or foot, is provided with the SX autoclaves. To open the lid, the lid lock is released by stepping on the foot pedal locates at the bottom while pressing the lid down. The lid can be opened with minimal effort owing to mechanical assistance. In addition, the lid can be closed easily just by pressing it down.

User-friendly Memory Function

Once turned on the system automatically sets and displays a pre-set value. Operation is done simply by pressing the start switch. ES-315/ES-215 enables the set temperature and time for each mode program to be stored in its memory.


*The control panel lighting image shown above may vary from actual display.

MODE/PROCESS display enables real time monitoring of operation status.

ES-315 / ES-215 offers three mode programs.

5Sterilization Mode
It contains a delay start timer function that allows operation to start 1 to 99 hours later.

 6Sterilization/warming Mode
This mode is useful when not removing culture media from the autoclave immediately after sterilization. Sterilized media can be kept warm to prevent coagulation.
 7Heating Mode
This mode program automates the dissolution of culture media that can sometimes be a painful process when using a water bath to boil them.

User-friendly design allows for even more easy maintenance.

Chamber having a flat inner surface

All models are supplied with stainless steel wire mesh baskets. No protrusions on inner surface of the chamber enable smooth loading and unloading of the basket as well as block design of all pipe fittings ensures safe operation.

Front access for easy maintenance

The exhaust bottle to capture and store exhaust steam is placed on the front panel of the autoclave unit. Access to the chamber for replacing water inside, as well as for routine maintenance and inspection, is done on the front of the unit, which also permits operators to replace bellows, saving costs for services by the service personnel.

A microprocessor controlled monitoring system provides safe sterilization.

Incomplete sterilization protection

In case of abnormal chamber temperature rise, the autoclave stops its operation. In case of abnormal decrease in temperature, the sterilization timer is temporarily suspended and then reactivated when the set temperature is reached.

Chamber overpressure protection

If overpressure in the chamber is detected, the autoclave stops all the function and indicates an error message simultaneously.

Chamber interior overtemperature protection

If the temperature inside the chamber exceeds the set temperature by 5°C or more, the autoclave stops all the function and indicates an error message simultaneously to avoid overheating.

Chamber exterior overtemperature protection

The thermostat switch detects the temperature of chamber exterior wall, which allows the autoclave to stop all the function if the temperature exceeds 130°C.
