Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Lok, Nonsterile, 500/Pk Images
Featuring a hydrophilic cellulose acetate (CA) membrane rated at 0.45um, these 13mm syringe filters deliver fast, low-adsorption clarification of aqueous and biological samples. The 13mm membrane is held within an 18mm ultrasonically welded acrylic housing that bidirectionally supports the media for sample injection or aspiration, and it provides an effective filtration area of 0.76 cm2 with a holdup volume of less than 50 microliters. Female Luer Lock inlet and Male Luer Lock outlet connections fit standard syringes, and the nonsterile units are supplied 500 per pack in yellow color coding for 0.45um identification.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic structure wets out readily for direct aqueous filtration without pre-wetting.
- Low protein binding and low nonspecific adsorption support maximum recovery of proteins and biological analytes.
- Uniform pore structure delivers consistent 0.45um particulate removal and reliable sample clarification.
- Thermally stable membrane suited to protein solutions, buffers, cell culture media, and biological fluids.
- PFAS-free verified construction for clean, low-interference sample preparation.
Key Construction Characteristics
- Ultrasonically welded acrylic housing, 18mm diameter, integrity tested to eliminate filter bypass.
- Female Luer Lock inlet and Male Luer Lock outlet (Luer-Lok/Luer Lok) for secure syringe attachment.
- Effective filtration area of 0.76 cm2 with a holdup volume under 50 microliters to conserve costly samples.
- Maximum operating temperature of 50 degrees C and maximum operating pressure of 80 psi.
- Nonsterile, supplied 500 per pack, color coded yellow for the 0.45um rating.
These filters maintain consistent flow and dependable particulate removal across routine clarification workflows. The low-binding cellulose acetate membrane protects sample integrity by minimizing analyte loss, making the device well suited to protein-containing and biological solutions. Each unit is individually labeled with its membrane material and pore size for easy identification outside the original packaging.
