Nitrocellulose Membrane Filters, 8.0um, 47mm, Hydrophilic, Nonsterile, White, 100/Pk
GVS SKU: 1215456

Featuring a naturally hydrophilic nitrocellulose (mixed cellulose ester) membrane composed of inert cellulose nitrate and cellulose acetate polymers, this 8.0um, 47mm disc delivers fast flow rates and high throughput across clarification and analytical workflows. The uniform microporous structure wets out without cytotoxic wetting agents, supporting clean, reproducible results. Each white, nonsterile membrane is supplied in a convenient 100/Pk dispenser.

Key Nitrocellulose Membrane Characteristics

• Naturally hydrophilic: Wets out readily for aqueous filtration without surfactant treatment.
• Uniform microporous structure: Provides consistent flow and diffusion rates with high throughput.
• Low extractables: Less than 4 percent extractables for more consistent, contamination-free results.
• Low ash content: Yields a residue of less than 0.045 percent of initial weight for gravimetric analysis using ashing techniques.
• Biologically inert composition: Cellulose nitrate and cellulose acetate polymers contribute no contaminating fibers.

Key Construction Characteristics

• Membrane material: Unsupported nitrocellulose (MCE), hydrophilic.
• Pore size and diameter: 8.0um pore size, 47mm diameter disc.
• Membrane thickness: 150um.
• Color and grid: White, plain (non-gridded).
• Sterility and pack: Nonsterile, 100 per pack. White membranes are autoclavable at 121 degrees C.

This 8.0um membrane maintains dependable, lot-to-lot consistent performance for particulate removal and clarification of aqueous solutions. Its fast flow and high throughput help preserve sample integrity while minimizing extractable contamination. The biologically inert, low-ash construction makes it well suited to demanding analytical and microbiological procedures.

• Particulate-Matter Analysis The 8.0um pore captures larger particulates for gravimetric and particle-loading assessments.
• Clarification of Aqueous Solutions Removes coarse particulates from aqueous samples ahead of downstream processing.
• Microbiological Analysis Supports culture-based and contamination monitoring workflows on a biologically inert membrane.
• Industrial Hygiene Procedures Suited to airborne and environmental particulate collection for occupational analyses.
• Gravimetric Analysis with Ashing Low ash residue (under 0.045 percent) enables accurate weight-based determinations.
• Prefiltration The open 8.0um structure protects finer downstream membranes from heavy particulate loads.
