SKU: T50.000.00 Category:


Fast and compact lab autoclave sterilizer.

Small footprint and maximum capacity in the least amount of space. Fits any lab!




Rapid cooling action. Tomy SX-500 Lab Autoclave comes standard with a dual fan system, which reduces the cooling time by 42% compared to non-fan-equipped autoclaves. Thus, shortening overall operation time and reducing the possibility of burns.


Easy installation. Just plug it in and add water! Whereas some lab autoclaves need plumbing or vacuum connections, Tomy Autoclaves are simple to install.

TOMY Fast Lab Autoclave SX-Series Lid and foot pedal

Intuitive operation. Because of a well-designed LED display, the Tomy SX-500 Lab Autoclave is easy to monitor. The foot-pedal assisted mechanical lid makes for easy opening. And wheels allow for effortless movement and storage.



5 Convenient Sterilization Settings. First, a Liquid Sterilizing Course which helps prevents boiling over. Second is the normal Sterilizing Cycle. Next the Sterilizing–Warming Course prevents coagulation, hardening, or freezing of culture media after the sterilization ends. Then the Heating–Warming Course, which is convenient for heating and dissolving culture media. Last, a Memory Recall setting, which allows you to repeat previous settings.


Space-Saving. The main body of the SX-500 autoclave is compact because of the vertical design. Vertical autoclaves are ideal for maintaining high capacities in a compact lab setting. In addition, installation space at the side of the autoclave is not required, as compared to autoclaves using a slide-open lid.


Designed to be reliable and simple. Made of high quality, durable materials. Because Tomy focuses on quality, we help create the best user experience possible, with minimal maintenance or downtime.
