Membrane selection
Find the membrane that fits your sample
Membrane choice should be checked against the sample solvent, analyte recovery, intended method and filter housing compatibility. Treat these as starting points; confirm the final selection against your method and product specification.
Nylon
Hydrophilic polyamideOften considered for general aqueous and organic sample filtration where protein recovery is not critical.
General sample preparationCheck for protein bindingPTFE
Hydrophobic membraneCommonly selected for organic solvents, gases and chemically demanding samples. Aqueous use normally needs an appropriate wetting step.
Organic solventsGas / vent workHydrophobicHydrophilic PTFE
Modified PTFEA broad-compatibility option to discuss for aqueous and organic sample types when a wettable PTFE format is required.
Aqueous + organicConfirm product-specific compatibilityPES
PolyethersulfoneOften used where aqueous biological samples, media or lower protein binding are important considerations.

Requirement-based selectionCheck sample compatibility| Membrane | Wetting | Typical applications | Compatibility guidance | Important caution |
|---|---|---|---|---|
| Nylon | Hydrophilic | General sample preparation | Check aqueous and organic compatibility for the product | Protein binding may affect recovery |
| PTFE | Hydrophobic | Organic solvents, gases and vents | Consider pre-wetting for aqueous samples | Confirm chemical and housing compatibility |
| Hydrophilic PTFE | Wettable PTFE | Aqueous and organic sample types | Confirm the exact product chemistry | Use product-specific compatibility data |
| PES | Hydrophilic | Aqueous biological samples and media | Review against aggressive solvents | Consider when low protein binding is needed |
| PVDF | Product dependent | Analytical and aqueous sample preparation | Check wetting and solvent compatibility | Validate analyte recovery for critical methods |
| Cellulose acetate | Hydrophilic | Aqueous biological solutions | Not suitable for every solvent | Confirm chemical compatibility |
| Regenerated cellulose | Hydrophilic | HPLC and mixed-solvent sample preparation | Confirm method and solvent compatibility | Validate if analyte recovery is critical |
| Polypropylene | Product dependent | Selected chemical and particulate filtration | Confirm solvent and application fit | Review manufacturer specification |
Selection guide
Answer four questions to narrow the filter configuration
Use the guide to identify a starting configuration. For a validated method or unfamiliar sample, share the solvent, analyte and method requirement before ordering.
What is the sample or solvent type?
Start with the liquid chemistry and any method requirement.
Pore size, diameter and sterility
Choose the pore and diameter around the method
0.45 µm and 0.22 µm are common starting points. The final pore size, diameter and sterile format should follow the method, sample volume, particulate load and required end use.
0.45µm · clarification
General particle removal and sample preparation
- Often used for routine clarification and many chromatography sample-preparation workflows
- Usually offers lower flow resistance than a finer pore
- Confirm the requirement against the analytical method
0.22µm · fine filtration
When a finer filtration step is required
- Commonly selected for fine sample preparation and sterile-filtering applications
- Higher particulate load can reduce throughput
- Confirm sterile claim, packaging and method requirement before order
13 mm
A compact option to consider for smaller sample volumes and limited bench-scale preparation.
25 mm
A commonly requested general-purpose diameter for routine laboratory sample preparation.
33 mm
A larger diameter to discuss for higher volumes or samples with more particulate load.

Buyer questions
Syringe filter FAQs
Practical answers for laboratory purchase teams and scientists. Confirm the final product specification against your actual method and sample.
What is the difference between 0.22 µm and 0.45 µm syringe filters?
0.45 µm is commonly used for general particle removal and sample clarification. 0.22 µm is a finer pore often selected when the method calls for finer filtration or a sterile-filtering format. Confirm the pore size against the method and sample.
Which syringe filter is best for HPLC?
There is no single best membrane for every HPLC method. Start with the mobile phase or sample solvent, analyte recovery, pore size requirement and any method validation data. Regenerated cellulose, PVDF, nylon and PTFE may be evaluated depending on the application.
Which membrane is suitable for organic solvents?
PTFE is commonly considered for organic-solvent filtration because it is hydrophobic. Hydrophilic PTFE and regenerated cellulose may be considered for some aqueous-organic applications. Confirm membrane and housing compatibility with the exact solvent and conditions.
When should I use PTFE syringe filters?
PTFE is commonly used for organic solvents, gases and vent applications. Native PTFE is hydrophobic, so an aqueous sample may require an appropriate wetting step. Check the selected product specification before use.
Are sterile syringe filters required for microbiology?
Sterile filters may be required when the filtrate must remain sterile, for example in relevant media or buffer preparation. The laboratory method and the selected product’s sterile claim should determine the final choice.
How do I choose between 13 mm, 25 mm and 33 mm diameter?
Diameter should follow sample volume and particulate load. 13 mm is often considered for smaller volumes, 25 mm for routine sample preparation and 33 mm for higher volumes or more demanding throughput. Confirm the final format against the chosen product.
Can syringe filters be used for aqueous and protein samples?
Yes, but membrane selection matters. Hydrophilic membranes are often considered for aqueous samples; when protein recovery is important, discuss low-protein-binding options and validate recovery for the method.
Can I order syringe filters in bulk?
Yes. Share the membrane, pore size, diameter, sterile requirement, pack size and expected quantity so suitable options and quotation support can be provided.
Do you supply syringe filters across India?
ScientificEdge coordinates laboratory supply requirements in Delhi NCR and across India. Share the delivery location and quantity for availability and quotation support.
What details are needed for a syringe filter quotation?
Please share membrane material, pore size, diameter, sterile or non-sterile requirement, sample solvent or chemical, quantity or pack size, and delivery location. An existing product code can also help.
