Andersen Refill Kits

In the Andersen system, the EtO is supplied in a glass ampoule which is held within a break-shield. Gas is delivered to the heart of the load, achieving the highest level of sterilisation for any given amount of gas.

The gas is released by breaking the ampoule. The EtO boils, giving a very distinctive bubbling and cooling feeling as it does so. This provides very clear, positive feedback that the ampoule has been properly activated.

The packaged items, ready to be sterilised, are placed inside the supplied sterilisation bag. The cabinet holds the space around the sterilisation bag below room pressure. This ensures that any leak is from the room into the cabinet. Any EtO released through the bag is taken to the outside through the exhaust tube at the back of the cabinet.

The bag volumes vary in size, giving great flexibility in the volume, size and shape of items that can be sterilised.

AN-79.16 Large Ampoule and Bag Refill Kit

The standard Anprolene refill kit comes with ampoules and liner bags for 14 cycles. The ampoules and liner bags are packaged in a convenient storage/dispenser box. Each ampoule contains 17.6 g of EtO, and the liner bag (sterilisation chamber) holds up to 40L. This kit is suitable for use with any Anprolene steriliser.


Technical Details

When packaged, each ampoule is surrounded by a fabric shield. The ampoule and this shield are sealed in a plastic bag which acts as the gas diffusion - or gas release-membrane.


Kit consists of:

  • 14 x 18cc Ampoules

  • 14 x 40 Litre Sterilisation Bags

  • Probe strap

Note: Dosimeters and humidichips are not included in this kit.

Andersen Dosimeter Chemical Indicator

Dosimeter 2.PNG

Time, temperature and EtO concentration are essential to successful sterilisation. The Andersen Dosimeters are chemical integrators that provide the operator with an immediate visual assurance that the requirements for sterilisation have been fulfilled. Provided the load has seen sufficient EtO, for long enough, at a high enough temperature, the blue line will go past the blue triangle mark.

The AN-87 Dosimeter is designed for cycles run at 20 °C–30 °C.  

To use, remove it from the foil packaging, and place in the least accessible area of the sterilization load. Use one Dosimeter per cycle.

AN-87 Dosimeter Chemical Integrator features:

  • Read results immediately

  • Reliable 

  • Easy to use for every sterilisation load
