ABSTRACT:
A filter cartridge that includes a track etched membrane sealed therein in a leak-free manner, and a method for making the cartridge. The filter cartridge has a bubble point that is at least 50% of the bubble point of the track etched membrane. In one embodiment, the method includes disposing the track etched membrane below a heat source and orienting the membrane so that it melts back on itself, and then allowing the membrane to cool to form a leak-free seal.
