Fluorodyne II filter cartridges are hydrophilic membrane filters designed for reliable retention of bacteria in the final filtration of bottled water.
The Fluorodyne II JSD filter was developed and validated to provide enhanced, secure and reliable removal of microorganisms from bottled water. The cartridge is constructed from serial layers of 0.2 and 0.1 micronpolyvynilydine fluoride (PVDF) membrane. The single open ended (SOE) configuration is designed to fit into sanitary housings to ensure effective microbial removal and assembly integrity.
The Fluorodyne II JSD filter is suitable for exposure to in situ steam sanitization cycles for longer service life.
This filter is integrity testable. An in-situ and non-destructive integrity test can provide assurance of filter performance within minutes. Integrity tests help manufacturers avoid costly issues such as product contamination, product losses, reprocessing and production delays, as well as satisfying auditor requirements.
Fixed pores, non-shedding, resin and surfactant free
Multiple adapter options for installation into sanitary housings
Repeated sanitization/sterilization capability for economical operation
Individually serialized for full traceability
Cartridges produced in a controlled environment
Manufactured according to ISO 9001:2000 certified Quality Management System
Microbial Removal Rating
Fluorodyne II JSD filter cartridges, passing an appropriate integrity test, provide a sterile effluent when challenged with Brevundimonas diminuta at ≥1 x 107 CFU per cm2 of effective filtration area.
Fluorodyne II JSD filter cartridges passing the appropriate Forward Flow integrity test have also been shown in laboratory tests to give titre reductions of typically 108 when challenged with Acholeplasma laidlawii ATCC28206 at a challenge level of 107 per cm2 filtration area.
