Featuring an unsupported, naturally hydrophilic mixed cellulose esters (MCE) medium composed of a mixture of inert cellulose nitrate and cellulose acetate polymers, this nitrocellulose membrane disc delivers rapid flow and high throughput for routine filtration and analysis. The white, nongridded disc measures 47mm in diameter with a 5.0um pore size and is supplied nonsterile in packs of 100. Its uniform microporous structure provides consistent flow and diffusion rates across the membrane surface.
Key Nitrocellulose Membrane Characteristics
- Naturally hydrophilic medium with a noncytotoxic wetting agent that wets out readily for fast, even sample distribution.
- Uniform microporous structure that provides among the fastest flow rates and highest throughputs available in a membrane filter.
- Biologically inert composition of cellulose nitrate and cellulose acetate polymers for dependable, lot-to-lot consistent results.
- Low extractables, yielding extractable levels of less than 4% of membrane weight for cleaner downstream results.
- Suited to gravimetric work, yielding a residue of less than 0.045% of initial weight when ashed.
Key Construction Characteristics
- Diameter: 47mm disc format compatible with standard filter holders and funnels.
- Pore size: 5.0um for coarse clarification and particulate retention.
- Color: White, nongridded surface.
- Sterility: Nonsterile, supplied 100 per pack.
- Autoclavable: Withstands sterilization at 121 degrees C for 20 minutes.
This membrane maintains consistent flow and diffusion rates that support reproducible particulate capture and sample clarification. Its biologically inert, low-extractable construction helps preserve sample integrity throughout filtration and analytical workflows. Lot-to-lot consistency provides dependable performance across repeated runs.
