Cath Lab ETO Sterilizer

Cath Lab ETO Sterilizer

Cath Lab ETO Sterilizer or hospital Eto sterilizer mainly uses to sterilize medical and pharmaceutical products that cannot support conventional high temperature steam sterilization – such as devices that incorporate electronic components, plastic packaging or plastic containers.

Ethylene Oxide gas infiltrates packages as well as products themselves to kill microorganisms that are left during production or packaging processes. This gas, mixed with air at a ratio of at least 3% ETO gas, forms an explosive mixture. Pure ETO gas boiling point is 10.73 ºC at atmospheric pressure. Most of the time, it is mixed with Nitrogen or CO2. EO Gas Sterilizers uses to sterilize ot surgical instruments and medical disposables.

The system has been designed to operate on single use disposable type, EO 100% gas cartridges of 40 / 100 / 170 grams. The chamber and all contact parts shall be made from S.S 304. The chamber has been provided with a single door, easy locking arrangement and silicon gasket for leak proof operation. Electronically controlled heating system to ensure uniform heating of the chamber at 50 degrees centigrade. The chamber is provided with a adequate capacity rotary vacuum pump enclosed in sturdy cabinet duly powder coated for durability. We provide four of control switches with built in indicator light to regulate evacuation, feeding of gas, fresh air inlet through filter and aeration facility. Ethylene Oxide Gas Sterilization Unit is compact stand-alone sterilizer chamber.




Exclusive Features of Cath Lab ETO Sterilizer

  • The cycle operates in vacuum and hence is safer to operate, as there is minimum chance of leakage.
  • The electronic design provides accuracy of operation, dependability and repeatability.
  • The sterilizer can aerate items after sterilization same Machine. The sterilization-aeration process can be continuous in one chamber and hereby eliminate gas exposure during load transfers to aerators.
  • After the sterilization cycle, the chamber is purged or aerated continuously until the door is opened. This prevents a buildup of ethylene oxide from items aerating in the chamber.
  • The actual volume is more than that of the Standard sterilizer, although the machine is compact in size.
  • The use of ‘VALVE’ makes the operation of the cycle very easy.
  • Ethylene Oxide Gas cartridges contain calculated quantity of EO 100%, which ensures the right concentration of EO to achieve Sterility.
  • Pure EO cartridges are very handy, easy to carry, store and to use.
  • As the cartridges are of single use type with fixed gas concentration in relation to chamber, over exposure which leads to higher residual level of EO gas in the sterilized products, and under exposure which leads to non-sterility are ruled off.
  • No more cylinder deposits.
  • No more hassles of cylinder transportation, EO cartridges are very light and can even be dispatched at a very short notice.
  • Operational Safety: – As the entire sterilization cycle operates under negative pressure (under Vacuum), possibilities of gas leakage/exposure to EO gas (as in the case of cylinder models) is almost nil.
  • A Vacuum cycle helps in an overall better performance of the machine and is very ideal for operational safety.

of Ethylene Oxide Sterilization

Ethylene Oxide Sterilization (Sterilization) offers various distinct advantages over the conventional steam sterilizers (sterilizers), being a DRY & COLD (operates at 50ºC ) process proves very useful in sterilization of expensive items, also it has got a unique penetration ability, so it is very useful in sterilization (Sterilization) of expensive and delicate items such as Cardiac catheters, Stents, IOL’s Tubing’s, various types of scopes, sharp surgical instruments etc., its unique mode of action, also enhances the life of several surgical accessories & disposables items thus making them perfectly reusable.

Types of EO Gas Sterilizers

We are one of the leading EO Gas Sterilizer manufacturer in India. We manufacture below two types of ETO sterilizers:

  1. Semi-Automatic Operation Mode EO Sterilizer: In this type of control mode there are analog type buttons onto control panel of the machine through which machine operation procedure will be done.
  2. Fully Automatic Operation Mode EO Sterilizer: This is PLC HMI based fully automatic control mode equipment in which there is HMI mounted onto control panel of the machine through which operation procedure done.
