S40™ Sterilant Concentrate is a proprietary, two-part formulation that was developed exclusively for use in the SYSTEM 1 EXPRESS / SYSTEM 1 PLUS Processing System.
S40™ Sterilant Concentrate delivers the pre-measured components from a single-use container. A proprietary formulation of dry powder Builders, the inert ingredients, is in the lower compartment of the container. When packaged, the upper compartment contains the active ingredient, a nominally 36.6% solution of peracetic acid (PAA). The two components are mixed with water during the automated cycle providing a use dilution capable of:
• Sterilization of processed endoscopes
• Inhibiting corrosion of metals, polymers, and other materials
S40™ Sterilant Concentrate is sporicidal, fungicidal, bactericidal, virucidal, & tuberculocidal.
Microbicidal Activity of S40™ Sterilant Concentrate:
Peracetic acid, the active ingredient in S40 Sterilant Concentrate, has been shown to attack and inactivate many different cellular mechanisms to achieve its microbicidal activity (Block, S. ed., Disinfection, Sterilization, and Preservation, 5th edition, 2001).
It is thought to act primarily as an oxidizing agent. Its activity was demonstrated under worst case conditions in performance and simulated-use testing. S40™ Sterilant Concentrate has been shown to be effective against the following organisms when tested under the operating conditions of the Processor:
