Cellulose Acetate Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Lok, Sterile, Yellow, 50/Pk
GVS SKU: FJ25ASCCA004FL01

Featuring a naturally hydrophilic cellulose acetate membrane with a 0.45 micron pore size, these sterile syringe filters deliver fast, efficient clarification of aqueous and organic solutions. The 25mm membrane is sealed inside a 33mm ultrasonically welded acrylic housing that bidirectionally supports the media, allowing both sample injection and aspiration. Each unit is supplied sterile in a pack of 50 and is color coded yellow for quick pore-size identification at the bench.

Key Cellulose Acetate Membrane Characteristics

• Naturally hydrophilic membrane wets out readily for consistent flow with aqueous and alcohol-based solutions.
• Low protein binding helps preserve analyte and protein recovery in biological samples.
• 0.45 micron pore size provides reliable particulate removal and sample clarification.
• Broad suitability for aqueous, organic, and alcohol solutions, buffers, and tissue culture media.
• Each filter is labeled with the specific membrane material and pore size for easy identification outside its original packaging.

Key Construction Characteristics

• Modified acrylic housing, ultrasonically welded and integrity tested to eliminate potential filter by-pass.
• Female Luer Lock inlet and Male Luer Lock outlet (FLL/MLL) for secure connection to syringes and downstream devices.
• Supplied sterile and color coded yellow, 50 filters per pack.
• 25mm membrane diameter housed in a 33mm housing with low hold-up volume for small or costly samples.
• Maximum operating pressure up to 75 psi.

These filters deliver dependable, low hold-up filtration that protects analytical instrumentation while maintaining sample integrity. The hydrophilic, low-binding cellulose acetate membrane minimizes analyte loss, and the integrity-tested acrylic housing provides consistent, leak-resistant performance across routine sample preparation.
