The asymmetric PES (aPES) membrane provides superior flow rates, excellent downstream cleanliness, and low protein binding for cell culture applications, like media, sera, and growth. The Nalgene Rapid-Flow 0.2 micron aPES membranes are stem cell tested and recommended for fluids requiring sterilization, while the 0.1 micron membrane is ideal for mycoplasma removal, and the 0.45 micron can be used as a clarifying pre-filter.
