Product Description
PES Syringe Filter for HPLC Sample Preparation
Disposable syringe filters with polypropylene body and PES membrane for reliable HPLC sample filtration. Ultrasonic welding ensures leak-proof performance under high pressure conditions.
Filter Membrane Comparison
| Filtration Media | Features | Applications |
|---|---|---|
| Nylon | Resistant to strong alkalis and organic solvents, naturally hydrophilic, uniform pore size, good mechanical strength, pH: 3-12 | Suitable for both aqueous and organic phases, alkali-resistant but not acid-resistant, strong protein binding capacity |
| MCE | Hydrophilic, low protein binding, not resistant to strong acids/bases/organic solvents, pH: 4-8 | Aqueous phase filtration, limited pH tolerance, protein filtration in biological samples |
| PES | Hydrophilic, low protein binding, high flow rate, high porosity, high throughput, pH: 1-13 | Biological media or serum filtration with fast filtration speed |
| PTFE | Hydrophobic, resistant to strong acids/bases/high temperatures, pH: 1-14 | Highly corrosive solutions, organic solvents, gases, strongest chemical compatibility |
| PVDF | Low protein binding, not suitable for highly corrosive liquids, cannot withstand DMSO/THF/DMF, pH: 2-12 | General biological filtration applications |
| RC | Hydrophilic, tolerant to most solvents, compatible with HPLC solvents, extremely low protein adsorption, pH: 3-14 | Aqueous or organic solvent filtration, protein recovery |
