Nalgene 569-0020-DS Filter System,500ml,ps,0.2um Pore (Pack of 12)

Thermo Scientific Nalgene Rapid-Flow Sterile Filter Units feature the Rapid-Flow multi-column membrane-support system. This proprietary system provides a uniform, consistent separation between touch points within the membrane, minimizing gap stress to maintain optimal flow. Filter units have tapered sides and "grips" to make units easier to handle. A wide base provides stability on the bench top. Lot number, catalog number, membrane type pore size, and expiration date are printed on the upper filter units for identification and lot traceability. A color-coded filter identifies membrane type at a glance. Choose from four membrane types: Polyethersulfone (PES) (Supor material from Pall Life Sciences) is the best membrane for cell culture fluids including media, serum, additives and buffers. The lowest protein-binding, lowest extractables option, these membranes will maintain protein balance. Rapid-Flow PES filters do not remove critical media components or add harmful elements, and embryonic stem cells grown in media filtered through these filters maintain normal growth and pluripotency.
