Method of sterilizing utensils, particularly those made from thermolabile materials

Abstract

Abstract 1. A process for sterilizing utensils, more particularly utensils made of a thermolabile material or having parts made of such materials, characterised in that the material for sterilization is first packed in sterile bags, then introduced into a chamber adapted to be closed in airtight manner, whereafter the air in the chamber is exhausted to a pressure in the range of 10-100 mbar and at least the material is heated to 40-42 degrees C, whereafter peracetic acid solution in a concentration of approximately from 4 to 7% of peracetic acid and from 93 to 96% of water is introduced into the chamber at the latter temperature for evaporation so that at a concentration of the evaporated peracetic acid of from 0.1 to 3.0 mg/litre an independent pressure increase to 50-140 mbar at 40 degrees C is produced, and the packed material is left in this environment for a sterilizing period of at most 150 minutes.
