® Operating Manual for Euroklav 23V-S Condensate+Heat=Steam Heat Heat Heat Heat Heat Drying For good drying it is essential that surplus heat be transferred to the objects which have been sterilized. In addition, the condensation must be led out of the sterilization containers. The floor of the containers have channels and the lid has an arched filter area. -
Page 48: Instruments
9.3.3 Instruments _____________________________________________________________________ Where appropriate, instruments should be disassembled before placing them in the autoclave, as this will improve the drying results. The use of lubricants (such as instrument oil) should be avoided unless absolutely necessary. Prior confirmation should be obtained from the manufacturer of such agents that they are in fact suitable for steam sterilization. -
Page 49: Stacking Sterilization Containers
The drying can be improved by the following measures: • Pre-heating the autoclave (empty sterilization) • Arranging transparent sterilization and paper packing vertically • Selecting the program option "Additional drying" • Extending the drying times (please consult your MELAG customer service).
