MCE (Mixed Cellulose Ester)
By the mixture of nitrocellulose and cellulose acetate, hydrophilic, chemical compatibility, low protein adsorption. The use temperature can not be higher than 40°C, the optimum pH range is 3-6. Particle analysis, particle removal, biochemical analysis, HPLC sample preparation for general media, and aqueous solutions. Can not be used to filter ethanol and alkaline solution.
Providing a broad range of chemical compatibility of the filtration of either aqueous or organic solvents, hydrophilic, can be used in a broad pH range.
PVDF (Polyvinylidene fluoride)
Extremely low protein-binding, for filtration of non-aggressive aqueous and mild organic solutions, or where maximizing protein recovery is important.
Low-affinity for proteins and extractable with substantially faster flow rates than PVDF; suitable for pre-filtration and filtration of buffers and culture media.
Extremely strong chemically resistant and is compatible with various sterilizing methods; ideal for gas and inorganic or organic samples in aggressive environments.
Lowest binding material available Hydrophilic and high throughput Strength and dimension stability Uniform pore structure.
