AN87 Dosimeter


Time, temperature and EO concentration are essential to successful sterilization.  Dosimeter integrators present visual assurance that all these parameters have been fulfilled.  Dosimeters change color in proportion to the dose of sterilant they contact.  View results immediately after sterilization.  No laboratory culture is necessary.  Use one Dosimeter per cycle.  (Not a BI substitute).


AN1071 Humidichip®


Designed specifically for use with Andersen EOGas™ and Anprolene®, this unique device ensures adequate Relative Humidity (RH) during the sterilization cycle.  Each single use pre-moistened 2" x 2" Humidichip releases up to 4 grams of water vapor.  Employ Humidchip® with a Humiditube™ in each sterilization cycle.


2 size Sterilization Bags


The Anprolene system uses unique plastic sterilization liner bags and individual gas ampoules.  We offer two different bag/ampoule combinations to match the size of your sterilization load. You never use more gas than you have to.
