Ethylene Oxide Sterilisation


We don’t tie you into a consumables contract!

Our Ampoules are often half the price of other makes!


What is ETO?

ETO is used for the sterilisation of delicates, taking 16hrs on either bench top or floor standing units, so is usually carried out overnight. The ETO comes in glass ampoules and is a toxic substance taking the form of liquid when below 11 degrees C, and a gas when above this temperature. It is simple to use – just put the items you wish to sterilise into a bag with the ETO ampoule, (various bag sizes are available) and then put the bag into the steriliser, the ETO ampoule is broken open and left for 16hrs. The steriliser is vented to remove ETO to the outside of the building. Equipment which needs to be stored and not used immediately can go into a sterilisation pouch before going into a big bag (the pouch shelf life is about 1 year – dependant on the pouch manufacturer). You will need an 11gm ampoule for a 60-litre unit and 20gm for the 135-litre unit.

Axis sterilisers are designed to comply with OSHA regulations and are manufactured by an ISO certified company and CE marked

Some of the items you can sterilise in the Axis system are:

  • Scopes
  • Catheters & Tubes
  • Surgical Instruments
  • Electrical Equipment – including Batteries
  • Syringes
  • Gowns & Masks
  • Bandages & Dressings
  • Respirators
  • Laparoscopic hand-pieces

Advantages of the Test unit over other suppliers:

  • You are not tied into a consumables contract (our ampules are half the price!)
  • The chamber is heated to 54C – this makes the ETO much more effective. Because ETO is a liquid at 11C and often these units are installed in cold outbuildings (NOT IDEAL, NOT RECOMMENDED) then in the winter you wonder if the sterilisation is very effective with some units! (If it has to be in a cold room then use a portable heater for 1/2 hr or so to heat up the room)
  • The unit alarms if the chamber does not reach 54C within 1/2 hour
  • The units are much less expensive as are all the consumables. So Practices are converting over to Test ETO ampoules that already have units from other suppliers
  • For the 60litre unit and the 135litre unit, it will cost the Practice less than £10 per cycle

An annual service will ensure:

    • the continued compliance
    • the steriliser is functioning correctly
