Cellulose Acetate Membrane Filters, 0.45um, 47mm, White, Nonsterile, 100/Pk
GVS SKU: 1215676

Featuring a supported, hydrophilic cellulose acetate medium internally reinforced by an inert polyester web, these 47mm membrane filter discs deliver a 0.45um pore size with naturally low protein binding for applications where maximal recovery of protein is critical. The internal support gives each membrane exceptional dimensional strength to prevent cracking, tearing, breaking, and distortion when handled or creased, while the low binding characteristics provide higher throughputs and reduce the number of filter changes during the filtration of proteinaceous solutions. Each disc is white, plain (not gridded), and supplied nonsterile in a pack of 100.

Key Cellulose Acetate Membrane Characteristics

Hydrophilic, naturally low binding: Pure cellulose acetate wets out readily and minimizes protein adsorption for high recovery of valuable samples.
Polyester-supported structure: An inert polyester web reinforces the membrane to resist cracking, tearing, and distortion under handling and pressure.
0.45um pore size: Provides reliable clarification and particulate removal across aqueous and biological samples.
Autoclavable: Dimensional stability allows the membrane to withstand autoclaving or steam sterilizing at temperatures up to 135 degrees C (274 degrees F).
High throughput: Low binding and exceptional strength deliver higher throughputs and fewer filter changes during proteinaceous solution filtering.

Key Construction Characteristics

Membrane material: Supported cellulose acetate with an inert polyester support web.
Format: 47mm diameter disc, white, plain surface (not gridded).
Mean thickness: 150um.
Sterility: Nonsterile.
Packaging: 100 discs per pack.

These discs maintain consistent flow and sample integrity throughout demanding filtration workflows, supporting dependable, reproducible results. The combination of low binding and a robust polyester-supported structure protects valuable proteins and biological samples while sustaining throughput, making the membrane well suited to laboratories that require maximum recovery and reliable performance.
