Thumbnail Filmstrip of PTFE Hydrophilic Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Featuring a naturally low protein binding, hydrophilic PTFE membrane with a 0.22um pore size, this 25mm syringe filter delivers fast, efficient clarification and sterile filtration of both aqueous and organic solutions. The membrane is held in a transparent polypropylene housing that supports the membrane bidirectionally, allowing either sample injection or aspiration. A Female Luer Lock inlet and Male Luer Slip outlet provide a secure, leak-resistant connection to standard syringes, and the unit is supplied nonsterile in packs of 100.
Key PTFE Membrane Characteristics
- Hydrophilic PTFE chemistry wets readily with aqueous samples while retaining broad compatibility with organic solvents, acids, and bases.
- 0.22um pore size provides sterilizing-grade retention for clarification and microbial removal.
- Low extractables and low protein binding help preserve sample integrity for downstream analysis.
- Suited to a wide range of solvents, making it well matched to chromatography sample preparation.
Key Construction Characteristics
- Transparent polypropylene housing for clear visual monitoring of filtrate and bidirectional membrane support.
- 25mm membrane diameter sized for typical sample volumes.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
- Nonsterile, supplied 100 per pack.
Each filter is integrity tested to confirm proper fit and weld, eliminating potential filter bypass for dependable, repeatable results. The clear housing and accurate labeling support easy identification and confident sample handling. Together these features help maintain sample purity from preparation through analysis.
