Read the full statement (325 words)
The SYSTEM 1E Liquid Chemical Sterilant Processing System, Model P6700, is intended for liquid chemical sterilization of cleaned, immersible, and reusable critical and semi-critical heat-sensitive medical devices in healthcare facilities.
The SYSTEM 1E Processor dilutes the S40 Sterilant Concentrate to its use dilution (>1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 45.5 to 60°C, and rinses the load with extensively treated* potable water. After completion of a cycle, critical devices should be used immediately; semi-critical devices should be used immediately or may be handled and stored in a manner similar to that of high level disinfected endoscopes. Critical devices not used immediately should be processed again before use.
The SYSTEM 1E Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices.
* The extensive treatment of EPA potable water consists of:
1. Pre-filtration through two pre-filters:
* Pre-filter A is a gross depth filter that removes approximately 2.5 micron or larger particles/contaminants.
* Pre-filter B is a surface filter that removes particles/contaminants > 0.1 micron.
2. UV Irradiation:
* During transit through the UV water treatment chamber, a UV dose sufficient to achieve a >/= 6-log reduction of MS?2 virus is delivered to the water.
3. 0.1 micron filtration:
* The water prepared by pre-filtration and UV irradiation is filtered through redundant, 0.1-micron (absolute rated) membranes to remove bacteria, fungi and protozoa > 0.1 micron.
The SYSTEM 1 endo Liquid Chemical Sterilant Processing System, Model P6900, is intended for liquid chemical sterilization of cleaned, immersible, and reusable semi-critical heat-sensitive medical devices and their accessories in healthcare facilities.
The SYSTEM 1 endo Processor automatically dilutes the S40 Sterilant Concentrate to its use dilution (> 1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 45.5 to 60°C and rinses the load with 0.2 micron filtered water.
The SYSTEM 1 endo Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices.
