Universal use
The steam sterilizer sterilizes on the basis of the fractionated pre-vacuum method. This ensures the complete and effective wetting or penetration of the items to be sterilized with saturated steam. This method makes it possible to sterilize all kinds of loads which occur in practice.
Large quantities
To generate the sterilization steam, the steam sterilizer uses a separate steam generator. At program start, steam is generated and conducted into the sterilization chamber. A defined pressure and a prescribed temperature is thereby given. The sterilization chamber is protected from overheating and you can conse instruments or textiles very rapidly and achieve excellent drying results.

Do not sterilize any liquids with this steam sterilizer. It is not approved for the sterilization of liquids.
In case of non-observance, the consequences could be delayed boiling, damage to the steam sterilizer and burns.

A significant prerequisite for safe disinfection and sterilization of sterilizing materials is the appropriate preparation, i.e. cleaning and maintenance of the sterilizing materials according to the manufacturer's instructions. Furthermore the materials, procedure employed are of significance.

After disinfection and cleaning, rinse the instruments if possible with demineralized or distilled water and subsequently thoroughly dry the instruments with a clean, non-fuzzing cloth.
Employ only cleaning materials which are suitable for steam sterilization. Ask the manufacturer about the cleaning materials.
In case of non-observance, residual dirt can possibly be loosened up during sterilization in the steam pressure. Rests of the disinfection and cleaning agents lead to corrosion. Increased maintenance requirements and impairment of the function of the steam sterilizers can be the consequence.
Unsuitable cleaning materials, e.g. water-rejecting cleaning materials or steam-impermeable oils, can result in unsterile instruments. This endangers your health and the health of your patients.

Air leakage – checking the air leakage
Air leakage is a poorly sealed location through which unwanted air can enter or escape; Checking the air leakage serves to verify that the volume of the air leak in the sterilization chamber during the vacuum stages does not exceed a value where it would prevents the intrusion of steam into the sterilizer load, and that the air leakage is not a possible cause of a renewed contamination of the sterilizer load during drying

From lat. aqua destillata; also designated as aqua dest; water, which is largely freely of salts, organic materials and microorganisms, is obtained by distillation (evaporation and subsequent condensation) from normal tap water or pre-cleaned water. It is employed here as feed water
Dynamic pressure test of the sterilization chamber
Serves to verify that the rate of the change of pressure occurring in the sterilization chamber during a sterilization cycle does not exceed a certain value, which could lead to damage of the wrapping material
