Mixed Cellulose Esters (MCE)

Description

Mixed Cellulose Esters (MCE) 

•    Composition: Mixed cellulose esters including cellulose nitrate and cellulose acetate, also known as nitrocellulose
•    High porosity provides superior flow rates
•    High protein binding can be blocked by pretreatment or utilized in applications
•    High purity: Triton-free
•    Autoclavable: Withstands autoclaving temperatures up to 130°C without adversely affecting bubble point, flow rate or microbiological recovery
•    Rapid wetting time: < 3 seconds to wet a 47 mm diameter disc with aqueous 1% methylene blue
 

APPLICATIONS 
•    Standard membranes for many laboratory applications including filter sterilizing biological fluids, microbiology, con- tamination analysis and air monitoring
•    Can be transparentized to view collected particles •    Gridded filters available for quantifying microbial growth
•    Available non-sterile or sterilized by ethylene oxide (EtO)

• Refractive index = 1.50
• Maximum operating temperature = 130°C
• Ash content 2 ~ 5 µg/cm2

Definitions:
*1. Bubble point is the minimum pressure required to force air through a membrane which has been prewet with water (0.1 µm membranes prewet with isopropylalcohol)
*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
