Polycarbonate PCTE Membrane Filters

	Low non-specific binding, translucent membrane with uniform, cylindrical pores
	"Screen-type" membrane retains particles on the surface of the membrane, minimizing entrapment within the filter
	Excellent chemical resistance with good thermal stability, non-hygroscopic and extremely weight-stable
	Black and white membranes available; use for epifluoescence or electron microscopy, sterility testing

Notes:
1.	Bubble Point is the minimum pressure required to force air through a membrane which has been prewet with isopropylalcohol
2.	Flow rate indicates initial flow rate at 10 psi using a KGS 47 filter holder:
Water: using prefiltered (0.1μm) water
Air: using prefiltered nitrogen
3.	Initial flow rate at 5 psi using a KGS 47 filter holder
