Membrane Filter

RC Membrane Filter

RC Membrane Filters are made from regenerated cellulose with no added wetting agents and reinforced with nonwoven material. They offer ultra-low protein binding, high protein recovery, and excellent chemical resistance. Suitable for both aqueous and organic solvents, they are designed for routine chromatography sample and solvent preparation, particle removal, and microbiological quality control in analytical laboratories.

Ultra-low protein binding and high protein recovery for sensitive biological samples
No added wetting agents ensure low extractables and minimal interference in analytical methods
Hydrophilic surface with wide compatibility across aqueous and organic solvents
High permeability supports fast filtration without compromising particle retention

Comparison

Compared With The Alternatives

Versus Nylon membrane

RC offers lower protein binding and higher protein recovery than nylon, especially in aqueous environments, but may have lower resistance to aggressive organic solvents

Versus PVDF membrane

RC has lower non-specific binding and better compatibility with aqueous samples, while PVDF offers superior chemical resistance in strong solvents

Versus CA membrane

RC has higher chemical resistance and lower extractables than CA, with better performance in both aqueous and organic solvents

Use Guide

How To Use It

Select pore size based on particle size: 0.22 μm for routine filtration, 0.45 μm for higher flow, 0.1 μm for ultra-fine particles
Use 0.22 μm for protein samples to minimise binding and maximise recovery
Ensure sample pH is within 3-12 and temperature below 90 °C
Pre-wet the membrane with water or compatible solvent before use to ensure full wetting
For sterilisation, choose autoclave, ethylene oxide, E-beam, or gamma irradiation based on equipment availability
Do not exceed 90 °C or pH outside 3-12 to avoid membrane degradation
