Summary
Product identification
Toray's 5K Ultrafiltration (TUF-series) membranes provide a molecular weight cut-off of 5,000 Daltons. These are net-wrapped (no tail), spiral-wound elements utilizing a hydrophilic polyethersulfone (PES) asymmetric membrane designed for maximum retention of milk and whey proteins and maximum productivity. 'HR' models incorporate a low flux membrane with maximum retention for special applications.
The product is a sanitary element for dairy and food processing.
