Mixed Cellulose Esters (MCE) Membrane Filters

	High purity, triton-free MCE or "Nitrocellulose" membranes are composed of a combination of cellulose nitrate and cellulose acetate
	High porosity for increased flow rates without compromising filter integrity
	Use for many standard laboratory applications, including filter sterilization, contamination analysis
	Available specialty membranes include Opticlear (for hot block acetone vapor test) and Hydrophobic Edge (HE) membranes

Notes:
1. Bubble Point is the minimum pressure required to force air through a membrane which has been prewet with water (0.1μm membranes prewet with isopropanol).
2. Flow Rates indicate initial flow rate at 10 psi using a KGS 47 filter holder:
Water: using prefiltered (0.1μm) water
Air: using prefiltered nitrogen
3. Porosity refers to the percent open area.
