The TOMY Multiple Shared Use Autoclaves SX-700 / 500 / 300 are designed to meet the sterilization needs for a wide variety of sizes and shapes of articles to be sterilized especially in the washing room or central autoclave room arranged for shared use among a few or several laboratories.

User-Friendly and Safety Features

Ergonomic Height Design

Ergonomic Height Design

The SX-Series Autoclaves are designed to be the perfect height
to quickly load and unload articles into the chamber.





Easy operation using the “Top-open lid”Easy operation using the “Top-open lid”

A top-open lid, which can be operated easily with a single hand and a single foot, is provided. 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 quickly just by pressing it down.


Intuitive DisplayIntuitive Display

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




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.

Attentive Liquid Sterilization CourseAttentive Liquid Sterilization Course

When autoclaving liquid samples, opening the lid while the liquid temperature is high may cause a sudden boiling. It is necessary to allow the pressure and temperature to drop naturally without forced exhaust after sterilization.
The SX-Series Autoclaves have a LIQUID course that automatically sterilizes like this process with a single operation. It reduces spillage of media or solvent inside the chamber and supports smooth shared use in your facilities.

Printer supporting to keep Sterilization Log

Do you have any experience where you were worried if the sterilization was performed as set when you use a shared autoclave in a remote washroom or an autoclave room?
The Optional Printer can print out the operating parameters, chamber temperature, chamber pressure, the temperature of articles to be sterilized *, and the sterilization cycle process.


High Altitude Sterilization Program

Autoclave operates by generating steam under pressure and temperature. Therefore, its sterilization process can be greatly affected by the atmospheric pressure at the location where the autoclave is installed.
The SX-series Autoclaves allow users to operate even though at high altitude place**.

More Secure Sterilization considering Heat Transfer Time Lag

There is Heat Transfer Time Lag when using the steam autoclave. The display shows the ambient temperature inside the chamber, but the temperature of the articles to be sterilized arrives later than the display temperature. This is called “Heat Transfer Time Lag“.
For more secure sterilization, it is recommended to add the Heat Transfer Time Lag to the sterilization time.

Automatically timer countdown by sample temperature w / External Temperature SensorAutomatically timer countdown by sample temperature w / External Temperature Sensor

The SX series Autoclaves can check the temperature of articles to be sterilized with an optional External Temperature Sensor. The detected temperature by the External Temperature Sensor can be used to count down the sterilization time (e.g. 20 min.). That means sterilization will be done with the temperature of articles inside the chamber automatically without calculating Heat Transfer Time Lag manually by yourself.
The detected temperature also works to open the lid safely after sterilization. The lid can be opened after the temperature of articles drops down* and it prevents the sudden boiling of liquid sample.
These features help you to save time to decide the sterilization time and to reduce troubles of spillage for media or solvent.

Secure Sterilization

Secure SterilizationFine Pressure Adjustment

Secure Sterilization condition is created by saturated steam that temperature and pressure keep the balance for a certain time.
The SX series Autoclaves heat water in the chamber and create steam. The generated steam is discharged with air from the chamber to approach the saturated steam condition.
When air remains in the chamber, the balance of temperature and pressure breaks and it makes pressure rise.
Fine Pressure Adjustment monitors temperature and pressure, works automatically to remove residual air from the chamber, and adjusts pressure to approach ideal conditions for more effective sterilization.


Cooling Fan System

The SX series Autoclaves are standard-equipped with a dual-fan cooling system, shortening overall operation time. The Cooling Fan System reduces cooling time compared to non-fan operation. It will save you time and give you more to focus on other things.
