According to ASTM F838 methodology, checking bacterial retention capability of membrane or filter at a minimum concentration of 107cfu/cm2 of filter surface area, under simulated process conditions.
> Particle entrapment
Carry out particle retention experiment. Determine the retention ratio for specific size.
> Extractable
Identification the chemical components that migrate from membranes or filters into a drug product or process liquid in proper solvents in worst case. It indicates maximum possibility of chemical components migrating from membranes cartridges.
> Chemical Compatibility
Determine the membrane or filter whether or not can be used for specific process liquid.
> Integrity Test
Recommend suitable integrity test method for medical filter.
