Description
Advantec MFS™ Cellulose Acetate Membrane Filter 0.45 µm Pore Size, White, Plain, Nonsterile, 90 mm Diameter, 25/Pk, C045A090CFeatures:
¹ Bubble point is the minimum pressure required to force air through a membrane which has been prewet with water ² Flow Rate indicates initial flow rate at 10 psi using a KGS 47 filter holder Water: using water prefiltered to 0.1 µm pore size Air: using prefiltered nitrogen at 10 psi³ Porosity refers to the percent open areaOther Cellulose Acetate Membrane Filters Available:
- Composition—mixture of cellulose triacetate and diacetate
- Low statice charge and high strength
- Autoclavable—may be repeatedly sterilized without loss of integrity or adversely affecting bubble point
- Rapid wetting time—< 3 seconds to wet a 47 mm diameter disc with aqueous 1% methylene blue
- Lowest aqueous extractables (0.1 wt %) of all Advantec™ membranes
- Relative to MCE (Mixed Cellulose Esters, Nitrocellulose):
- Should be prewet prior to loading into a holder and autoclaving
- Enhanced recovery of fastidious gram positive organisms
- Filtration of enzyme solutions
- Diagnostic cytology
- Receptor binding studies
