Frequently Asked Questions
How do I choose the right pore size and membrane?
Use 0.22 μm for sterile filtration, 0.45 μm for clarification and HPLC sample prep. Choose membrane chemistry by compatibility: PTFE for organics, PVDF for proteins, nylon for general aqueous, cellulose acetate for low protein binding.
What specifications matter for laboratory filters?
Pore size, membrane material, housing material, diameter, hold-up volume, maximum pressure tolerance, sterility, and chemical compatibility. For sterile filtration, look for 0.22 μm sterilizing-grade certification.
Are pre-sterilized filters available?
Yes. Sterile-packaged syringe filters, bottle-top filters, and membrane discs are available with gamma- or autoclave-sterilization. Check individual product specifications for sterility documentation.
What chemical compatibility should I check?
Aqueous samples: cellulose acetate, PES, nylon. Organic solvents: PTFE, regenerated cellulose. Strong acids/bases: PTFE preferred. Always verify chemical compatibility charts for specific solvents before filtration.
