| Mixed Cellulose Esters (MCE) Membrane Filters (aka Nitrocelluose) |
| 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. |
