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.

• Wetting time: <3 seconds to wet a 47 mm diameter disc with aqueous 1% methylene blue
• Refractive index = 1.47
• Maximum operating temperature = 180°C
• Ash content 1.5–3.5 µg/cm2
 
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
