GD/X 25mm Sterile Syringe Filter, CA Filteration Medium, 0.2um (50pk)
Whatman SKU: 6901-2502

Whatman GD/X Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 6901-2502

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Low-binding cellulose acetate preserves dilute proteins in the filtrate while delivering sterile-grade retention at sub-micron pore sizes and wets easily with aqueous buffers. Polypropylene construction maintains a low-dead-volume internal flow path and resists degradation from routine sample matrices. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Very low protein binding supports high recovery of dilute samples
• Sterile-grade retention at sub-micron pore sizes
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Naturally hydrophilic surface wets readily with aqueous samples
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Reliable housing-to-membrane seal prevents bypass at rated pressure

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
