3. Apply to aqueous and organic solvent
◆ Nylon Membrane
1. General filtration
2. Compatible with a broad range of solvents
3. Clarification of aqueous and organic solutions
◆ PVDF Membrane
1. High flow rates and throughput
2. Low extractables
3. Broad chemical compatibility
4. Bind far less protein than Nylon or PTFE membrane
◆ MCE Membrane
1. High flow rates and throughput
2. Excellent thermal stability with very low adsorption
3. Suitable for aqueous solution
◆ PES Membrane
1. Minimizes loss of key proteins
2. Binds significantly less protein than cellulose or Nylon
3. High Flow Rate
4. Liquid of high temperature filtration.
5. Use with aqueous samples, proteins, acids, alcohols, aliphatic hydrocarbon.
6. Don't use with concentrated sulfuric acid, concentrated nitric acid, strong polar solvents.
◆ CA Membrane
1. Filtration for aqueous sample
2. Cell Retention for liquid
3. Minimizes loss of proteins
4. Binds significantly less protein than cellulose or Nylon
5. High Flow Rate
