ETO Sterilizer Features
Pre conditions: The product is exposed to a warm, humid environment for at least 12 hours (70%RH, 55°C) to ensure the product is at a uniform temperature and Humidity.
Exposure: Vacuum is pulled and EtO gas is introduced. The product is exposed for 4-8 hours usually. During the process the RH is kept at approx. 70% and the temperature at 55 °C.
Post conditions: The EtO gas is removed by repeatedly pulling a vacuum and then introducing air into the sterilization chamber until the EtO gas is cleared out (8-12 hours).
It should be noted that there is no standardized cycle for EtO sterilization. Generally there is a tremendous variety in exposure times and gas concentration.
The size of the sterilizers can range from small bench-top sterilizers to large rooms. Because of problems with toxicity and risk of explosion, many companies are choosing to contract out this work rather than perform it themselves. EtO use is therefore becoming very specialized and used by a small number of contract companies. A large part of all medical devices are sterilized by the EtO method.
Inner Seal: The chamber will be fabricated with a complete argon welded SS 316/304 nonmagnetic sheet.
Heating : Water immersion Type Heating Element is fitted in Boiler which is made of SS316 .
Vacuum : Vacuum pump/ventury for vacuum pulsing and air wash is used.
The machine is provided with PID based or PLC based automation along with an LCD HMI which allows the operator to:
Software for controlling, monitoring and recording of various parameters is provided. This makes it is possible to operate and monitor the machine by connecting it with any computer where the software is loaded, apart from running it from the machine itself.
The above devices control and regulate all the functions of the machine. It makes the system user friendly and allows the operator to change the process parameters as and when necessary.
The advantage of the above is that the system can carry out multiple programs. It includes features like
Cycle Record (Optional):
Piping & Valves : All the fittings used for the accessories and the main vessel are fabricated from SS 316 stainless steel. All the valves used in the process lines are SS 304/brass/Teflon construction Ball valves. (All standard makes) .
Testing : Pressure testing and vacuum testing as per specified standards. (1.5 times the working pressure)
Operation : The door closing is manual.
