Selection reference for filter membranes: (Specifically depends on chemical compatibility)

1. For hydrophilic samples suitable for filtering water-based solutions, choose hydrophilic membrane discs. Available membrane discs include: CN-CA (water membrane), PES membrane, nylon membrane, PP membrane, etc.
2. For highly corrosive organic solvents: choose membranes such as PTFE.
3. For protein solutions, choose membranes with low protein adsorption, such as CN-CA, PES, PTFE, and PVDF hydrophilic membranes.
4. For ion chromatography: generally choose PES filter membranes.
5. For gas and steam filtration, choose hydrophobic membranes such as PTFE or PVDF.
6. For high-temperature liquids, choose PES filter membranes, PVDF hydrophilic, or PTFE hydrophilic membranes.
