STI ’ s products have been specifically designed for the pharmaceutical industry. All materials of construction have been carefully selected and have passed USPXXII Class 6 testing.
Our membranes provide you with a wide range of chemical compatibility and molecular weight cut-off (MWCO) for Ultrafiltration and Nanofiltration applications. They range from; (300-500, 1000, 4,000, 5,000, 8,000, 10,000, 30,000, 50,000, &100,000 MWCO) in several different polymeric formulations and filter configurations.
Membranes are cast on a polypropylene and or a polyester backing with a carefully selected adhesive, which provides for a wide range of solvent compatibility for use in many varied applications. Design configurations provide for use in stirred cell discs, cassette and spiral housings .
Bench Top / Small Scale R&D;
Use a stirred cell disc for initial compatibility testing, then scale up to either a 5 sq.ft. cassette, or a 1 sq.ft. spiral before pilot or production use. Cassettes or full fit spiral housings up to 70 ft-² per module. The spirals are easily scaled, utilizing the same materials of construction throughout the product line. This permits real life evaluations and realistic LMH flux estimates. The unique optimized full fit spiral design eliminates the need for a U-cup type seal resulting in low hold-up volumes and maximizes the effective membrane area resulting in a very competitively priced - cost efficient system for small to very large applications.
