Thumbnail Filmstrip of PTFE Syringe Filters, 0.45um, 13mm, Hydrophilic, Luer-Lok/Luer Slip, Nonsterile, 500/Pk Images
Featuring a hydrophilic PTFE (polytetrafluoroethylene) membrane with a 0.45um pore size, this 13mm syringe filter delivers fast, efficient clarification of aqueous, organic, and alcohol-based solutions. The naturally wettable PTFE membrane combines broad chemical compatibility with low extractables, making it well suited to demanding sample preparation across analytical workflows. The transparent polypropylene housing measures 18mm in diameter and provides a 0.76 cm squared effective filtration area, while the low holdup volume of less than 50 microliters helps protect small or costly samples.
Key PTFE Membrane Characteristics
- Hydrophilic PTFE membrane wets readily with aqueous solutions while retaining the inherent chemical resistance of PTFE.
- 0.45um pore size provides effective particulate removal and clarification ahead of analytical instrumentation.
- Broad chemical compatibility supports filtration of aggressive organic solvents, acids, and bases.
- Low extractable levels help preserve sample integrity for sensitive chromatographic methods.
- 13mm membrane diameter with a 0.76 cm squared effective filtration area balances throughput with low holdup.
Key Construction Characteristics
- Transparent polypropylene housing, 18mm housing diameter, ultrasonically welded for a secure, bypass-free seal.
- Luer-Lok inlet and Luer Slip outlet connections for compatibility with standard syringes.
- Nonsterile, supplied 500 per pack.
- Holdup volume of less than 50 microliters minimizes sample loss.
- Maximum operating temperature of 90 degrees C and maximum operating pressure of 80 psi.
The bidirectionally supported membrane allows both injection and aspiration without compromising filter integrity. Each device is integrity tested to confirm a proper filter fit and weld, helping eliminate the risk of filter bypass. The result is consistent, reproducible filtration that preserves sample integrity for reliable downstream analysis.
