Description
Vitipore™ II and Vitipore II Plus cartridges have a unique, patent-pending end cap and are built to support very demanding process conditions. Their mechanically robust design combined with high microorganism retention capabilities makes these filters uniquely suited for the microbiological stabilization of a variety of beverage products.
Vitipore II cartridges are constructed of a polyvinylidene fluoride Durapore® membrane with polypropylene molded components, offering broad chemical compatibility with commonly used sanitizing agents. The ability of these cartridges to withstand repeated cleaning and sanitizing cycles leads to longer filter life and lower overall filtration costs.
Vitipore II Plus cartridges have an additional prefilter layer of cellulose esters for higher throughputs, longer filter life, and better performance, particularly in difficult-to-filter liquids with heavy particulate load or high colloidal content.
Ideal for the removal of particles and beverage spoiling microorganisms
- Innovative cartridge design generates high flow rates and increased durability
- Superior mechanical robustness resulting from a unique, patented end-cap design
- Ultra-thin, polyvinylidene fluoride membrane ensures product quality and taste
- Ease of cleaning and chemical compatibility extends the filter life for lower overall filtration costs and improved process economics
- Wide selection of configurations to meet your process needs
Regulatory Compliance
Vitipore II and Vitipore II Plus cartridges are 100% integrity tested during production. Each filter package includes a Certificate of Quality, which certifies that the filters meet Quality Assurance lot release criteria. The Certificate of Quality includes the microorganism retention claims.
Vitipore II are manufactured in a facility whose Quality Management System is approved by an accredited registering body to the ISO 9000 Quality Systems Standard.
Typical Applications
Applying membrane filtration to the manufacturing of wine, cider, beer, bottled water and other beverages helps ensure complete removal of particles or microorganisms.
Constructed with Durapore polyvinylidene fluoride membrane Vitipore II and Vitipore II Plus are ideal for beverage applications where attention to filtration costs, ease of cleaning, compatibility, durability and low extractables is essential.
