Detailed Application: Biological sample preparation; Very low protein retention: protein and enzyme filtration with very low protein retention. Filtration of protein-containing solutions with minimal protein loss; Sterilization and clarification; Receptor binding studies; Tissue culture media sterilization; Particle removal of cellular constituents from solution: The 0.22 µm membrane is the filter of choice for sterile filtration of aqueous solutions such as nutrient media, buffers and sera; The 0.45 μm membrane is a very convenient filter type for the reduction of particles and microorganisms in aqueous solutions such as nutrient media, buffers and sera. Enhanced recovery of fastidious gram positive organisms. The 0.8 and 1.2 μm membranes are used for the particle filtration in samples where a low adsorption is required. The 5.0 μm membrane is used for the coarse particle filtration in samples where a low adsorption is required.
