Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Lok, Nonsterile, 100/Pk Images
Featuring a naturally hydrophilic cellulose acetate (CA) membrane with low protein binding, these PFAS-free syringe filters deliver maximum sample recovery during the clarification and sterile filtration of aqueous solutions. The 0.22um membrane measures 25mm in diameter and is housed in a 33mm modified acrylic body, colored blue, that bidirectionally supports the membrane for sample injection or aspiration. Each nonsterile filter pairs a female Luer lock inlet with a male Luer lock outlet and ships 100 per pack.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic structure wets out readily with aqueous samples and buffers.
- Low protein binding for maximum recovery of proteins and other large organic molecules of interest.
- Uniform pore structure throughout the membrane for consistent 0.22um retention.
- Well suited to protein, cell culture media, and enzyme filtrations as well as biological fluids.
- PFAS-free construction supports trace analysis where fluorinated interferences must be avoided.
Key Construction Characteristics
- Modified acrylic housing, blue, with a 33mm outer diameter that bidirectionally supports the membrane.
- Female Luer lock inlet and male Luer lock outlet (Luer-Lok/Luer Lok) connection.
- Nonsterile, supplied 100 per pack.
- Increased operating pressure up to 75 psi.
- Maximum operating temperature of 90 degrees C (194 degrees F).
The low hold-up volume and improved flow channel design provide efficient processing of small or costly sample volumes while minimizing loss. Integrity testing of the filter fit and weld helps eliminate potential bypass, maintaining sample integrity. The combination of a low-binding hydrophilic membrane and a robust acrylic housing delivers reliable, repeatable clarification and sterile filtration results.
