Questions about Filtration

Syringe filter, membrane filter or filter paper?

It depends on volume and purpose. For a few millilitres, such as an HPLC sample or a small sterile volume, use syringe filters. For larger volumes on a vacuum or pressure setup, and for microbiological analysis of water, use membrane filters in a filter holder. For coarse separations, qualitative work or gravimetric analysis, filter paper is the simple and economical choice. For process volumes, filter cartridges and capsules are the next step. Tell us your volume and liquid: sales@luminixhealth.com.

Which pore size?

Use 0.45 µm to clarify samples and remove particles before analysis, for example before HPLC. Use 0.2 or 0.22 µm when you need sterile filtration, such as for buffers, media and heat-sensitive solutions. For liquids with many particles, put a glass-fibre prefilter in front of the membrane: with a retention of around 0.7 to 1 µm it keeps the membrane from clogging. The glass-fibre syringe filter, 0.7 µm, 30 mm is one example. Also choose a membrane material that is compatible with your solvent.

Why Filtration?

Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
