Disposable syringe filter body are typically made of polypropylene (PP) material, the membrane filter layer incorporated can be PES, PTFE, Nylon, or other filter media depending on specific purposes.In HPLC (High-Performance Liquid Chromatography), choosing the appropriate filter membrane depends on specific experimental conditions and the application of liquid chromatography.
Each material has its unique advantages and scope of application:
| Filtration Media | Features | Applications |
| Nylon | ◎Resistant to strong alkalis and organic solvents, naturally hydrophilic
◎No need for pre-wetting before use, uniform pore size, good mechanical strength
◎PH: 3-12 | ◎Suitable for both aqueous and organic phases
◎Alkali-resistant but not acid-resistant, with strong protein binding capacity, not recommended for filtration of protein-containing liquids. |
| MCE | ◎Hydrophilic, low protein binding
◎Not resistant to strong acids, strong bases, or most organic solvents
◎PH: 4-8 | ◎Aqueous phase, limited pH tolerance range
◎Filtration of proteins in biological samples |
| PES | ◎Hydrophilic, low protein binding ◎High flow rate, high porosity, high throughput ◎Not resistant to organic solvents and strong acid-base solutions ◎PH: 1-13 | ◎Suitable for filtration of biological media or serum, with fast filtration speed. |
| PTFE | ◎Hydrophobic, resistant to strong acids, strong bases, and high temperatures
◎Suitable for filtration of highly corrosive solutions, organic solvents, and gases
◎PH: 1-14 | ◎Hydrophobic membrane filters organic phases
◎Hydrophilic membranes can be used for both aqueous and organic phases, with the strongest chemical compatibility, almost universally applicable; |
| PVDF | ◎Low protein binding,
◎Not suitable for filtering highly corrosive liquids
◎Cannot withstand DMSO, THF, DMF, dioxane, chloroform, etc.
◎PH: 2-12 | ◎Suitable for general biological filtration |
| RC | ◎Hydrophilic filter membrane, tolerant to most solvents
◎Compatible with HPLC solvents
◎Exhibits extremely low protein adsorption capacity
◎PH: 3-14 | ◎Filtration of aqueous or organic solvents
◎Protein recovery |
The Syringe filters from us are ultrasonic welded to guarantee no liquid or gas leakage while being subjected to high pressure. No membrane replacement or filter cleaning is required, the single-use syringe filters are a great help to lab staffs freeing them from the trivial and time-consuming preparation, and therefore are widely embraced by laboratories across the world.Syringe filters are ideal for HPLC sample preparation and GC-MS Sample Preparation.
The PES syringe filters we produce contains high performance hydrophilic PES membrane filter. And the PES membranes are manufactured in our 100,000 class facilities, while the body of the syringe filters are manufactured just a few miles away in our new Injection Molding workshop.
The following are the parameters of one of the PES syringe filters
| Filter Medium | PES |
| Membrane Diameter | 33mm |
| Membrane Pore Size | 0.22μm |
| Wettability | Hydrophilic |
| Filtration Area | 4.90cm² |
| Sample volume | 100~200ml |
| Max Operating Pressure | 87psi |
| Max Operating Temperature | 90℃ |

Features of PES syringe filters
- Hydrophilic membrane
- Very low adsorption for pharmaceuticals and proteins
- Good stability against organic acids and bases
- For aqueous and slightly organic liquids with higher flow rates
- Mechanically very stable
Applications
Syringe filters are ideal for HPLC sample preparation and other applications:
- HPLC/ GC-MS small volume sample preparation, purification and prefiltering.
- Biological products preparation.
- Culture medium, microbial medium, buffers, additives and drugs sample filtration.
- Strong corrosive solvents purification.
