Triple layer design improves efficiency

Published: 1-Jun-2004


Millipore's Polysep II media has an innovative triple layer design to improve process efficiency and extend the life of expensive final fillers. Offering high retention, flow rate and throughput, the new membrane configuration provides a reliable prefiltration solution for sterilising-grade membranes in aqueous-based applications.

Comprised of borosilicate glass media and two cellulosic membranes, the integrated 1.0mm/0.2mm/0.1mm media combines the dirt-holding capacity of a depth filter with the retention efficiency of a membrane filter. The combination offers an unsurpassed prefiltration solution for cell culture and other media filtration applications. In addition, the new Polysep II triple layer media is ideal for designing scalable solutions from bench top to full-scale manufacturing.

Polysep II triple layer media configuration is currently available in cartridge filters, and Opticap XL and XLT disposable capsules. The company says the new media will be added to OptiScale small scale devices later this year.
