Tips:

Water-system MCE (mixed cellulose ester) : MCE membrane is made of nitric acid and cellulose acetate. It has hydrophilic properties, good biocompatibility and low protein adsorption properties. MCE membranes are commonly used for filtration of biological solutions, biological analysis and water quality monitoring.

Water-system PES (polyethersulfone) : PES membrane has an asymmetric porous structure in its cross section to ensure high flow rate and high rejection. Used for filtration of water solution. It has good chemical stability and inert, alkaline PH stability, high compatibility and good temperature stability.

Nylon: Nylon films are naturally hydrophilic and are made of polyamide. Use without wetting agent, to ensure that the filtrate is not contaminated. The filter membrane is suitable for the filtration of aqueous solution and most mild organic solutions, especially alkaline and alcohol solutions. Due to the high absorbability of nylon membrane, it is generally not recommended to be used for filtration of biological samples such as culture medium or protein solution, in order to avoid the loss of samples due to adsorption.

PTFE: suitable for water system and various organic solutions, resistant to all solvents, low solubility. It has the characteristics of large gas flux, high particle retention rate, good temperature resistance, resistance to strong acid, strong base, organic solution and oxidizer, aging resistance and non-adhesion, non-flammable and non-toxic, biocompatibility and so on.
