MEMBRANE FILTER

How to Choose Right Syringe Filter — Filter Membrane Materials

 

How to choose right syringe filter is important for filtration. In this blog we are going to talk about the membrane materials used for manufacturing syringe filters. Please check the filter membrane chemical compatibility for the liquids you are going to filter.
GF Membrane

Hydrophilic material membrane. Excellent compatibility with organic solvents and strong acid (apart form hydrofluoric acid) and bases. High dirt-handling capacity.

NYLON Membrane

• For general sample and solvent filtration. (Compatible with broad range of solvent) • Excellent fo rmost HPLC & GC sample and solvent preparations. • Clarification of aqueous and organic solution.

PVDF Membrane

• High flow rates and throughput. • Low extractables. • Broad chemical compatibility. • Bimd far less protein than NYLON or PTFE membranes. • Membrane for clarification. • Aqueous and mild organic solution

PTFE-B Membrane

• PTFE membrane with supporting layer polyster or polyproylene. • Excellent chemical stability and particle retention. • Apply to organic solvent. • Organic solvent with strong chemical causticity filtration. • Strong acid solvent filtration. • Alkali solvent filtration.

PTFE-L Membrane

• PTFE membrane with supporting layer polyster or polyproylene. • Excellent chemical stability and particle retention. • Apply to aqueous and aggresive organic solvents. • For protein binding. • For Aqueous fluid without prior wetting.

MCE Membrane

• Apply to aqueous and organic solvent. • High porosity for increase flow rates.

PES Membrane

• Minimize loss of key proteins. • Binds significantly less protein than cellulose or NYLON. • High flow rate.

CA Membrane

• Filtration for aqueuos sample and some organic solvent. • Cell retention for liquid.
