ADVANTEC Membrane filter-Cellulose Acetate

ADVANTEC Membrane filter-Cellulose Acetate

◈ Product Information

　• Composition : Mixture of cellulose triacetate and diacetate
　• Characteristics : Low static charge and high strength
　• Autoclavable : Withstands autoclaving temperatures up to 130°C without adversely affecting bubble point,
　　flow rate or microbiological recovery
　• Clean : Lowest aqueous extractables (0.1 wt%) of all Advantec membranes
　• Relative to MCE (Mixed Cellulose Esters, Nitrocellulose):
　　　– improved solvent resistance to low molecular weight alcohols
　　　– better heat resistance
　　　– lower protein binding

► Applications
　• Enhanced recovery of fastidious gram positive organisms
　• Filtration of enzyme solutions
　• Diagnostic cytology
　• Receptor binding studies
　　Note: Should not be prewet prior to loading into a holder and autoclaving.

Definitions:
　*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 25°C air at 10 psi
　*3. Porosity refers to the percent open area
