- Unique concentric funnel shaped barrel increases volume and decreases back pressure
Product Selection Guide
Evaluate sample:
- Determine chemical compatibility, volume and need for prefiltration
Determine level of prefiltration necessary:
- In filter unit vs. prefilter unit in series for coarse precipitants.
Choose filter media type:
- Aqueous: Nylon, MCE, CA
- Non-polar: Nylon, PTFE, PVDF
- Protein: PVDF, PES
Choose barrel diameter:
- 10 mL: 13 mm diameter
- 100 mL: 25 mm diameter
Choose initial or secondary retention target:
Note: for all International Orders, the buyer will be solely responsible for the customs clearance, duty, and taxes imposed on the package.
Filter Material Specs
Filtration Media / Application Guide (hydrophobic or hydrophilic) Glass microfiber filter media - prefilter versions available in all variations except MultiDensity which includes prefilter
Polypropylene (PP)
- The polypropylene membrane is resistant to many organic solvents and slightly hydrophobic
- Useful for aqueous and organic solutions
- Low non-specific protein binding

Syringe Filter Capabilities
Beyond the extensive product selection found within our standard syringe filter list, we offer OEM capabilities for engineering, molding and insertion of many additional membrane and membrane/pre-filter options. We can work with most of our own membrane and specialty materials as well as convert your supplied product. Please contact us for full engineering capabilities as well as process flow and project management services in this field.
- Filter insertion in clean room by manual as well as fully automated means.
- Molding in place, over molding and support structure molding of fragile media.
- Ultrasonic welding of barrel structure for increased leak / burst resistance.
- Multi-process mold extensions for inclusion of single or multi-level prefiltration media.
- Digital variable print capabilities along arc on barrel face for identification purposes.
- Blister packing for EO and gamma sterilization.
- Pure virgin PP, verified by HPLC against U/L extractables.
