Cellulose Acetate Syringe Filters, 1.2um, 25mm, Luer-Lok/Luer Slip, Nonsterile, Red, 500/Pk
GVS SKU: FJ25ANCCA012CD01

Featuring a hydrophilic cellulose acetate membrane made from pure cellulose without added wetting agents, these 25mm syringe filters deliver fast, efficient clarification of aqueous and organic solutions. The 1.2um pore size handles higher particulate loads, while the very low protein binding character of the cellulose acetate membrane helps preserve sample integrity and maximize analyte recovery. A modified acrylic housing bidirectionally supports the membrane, allowing sample injection or aspiration, and each filter is color coded red for quick pore size identification at the bench.

Key Cellulose Acetate Membrane Characteristics

• Naturally hydrophilic, suitable for both aqueous and organic samples without the need for pre-wetting
• Made from pure cellulose without wetting agents, minimizing extractables that could interfere with analysis
• Very low protein binding capacity, helping to maintain analyte concentration and sample integrity
• Broad chemical resistance to a wide variety of solvents
• High wet strength with an operating pH range of approximately 3 to 12

Key Construction Characteristics

• Modified transparent acrylic housing with a 33mm housing diameter and a 25mm membrane diameter
• Female Luer Lock inlet and Male Luer Slip outlet for broad device compatibility
• Effective filtration area of approximately 4.6 cm with a low hold-up volume of less than 50 microliters
• Maximum operating temperature of 50 C and maximum operating pressure of 75 psi
• Nonsterile, supplied 500 per pack

These filters provide reliable, repeatable particulate removal across demanding sample matrices while the low hold-up volume conserves precious or costly samples. The integrity-tested construction guards against filter bypass, supporting consistent results and dependable sample preparation.

• Sample Clarification The 1.2um cellulose acetate membrane removes particulates and sediment from aqueous and organic samples to yield a clean filtrate.
• HPLC and GC Sample Prep Clarifies samples ahead of chromatographic analysis, protecting columns and instrumentation from particulate fouling.
• Particulate Removal Handles higher particulate loads at the 1.2um rating, making it well suited to coarse clarification of turbid solutions.
• Protein Solution Filtration Very low protein binding preserves analyte concentration when clarifying protein-containing samples.
• Aqueous and Alcohol Solution Filtration The naturally hydrophilic membrane filters aqueous and alcohol-based solutions without pre-wetting.
• Prefiltration Removes coarse particulates upstream to protect and extend the life of finer downstream membranes.
