Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Lok, Nonsterile, 500/Pk Images
Featuring a hydrophilic cellulose acetate membrane made from pure cellulose without wetting agents, these 25mm syringe filters deliver fast clarification of aqueous and alcoholic samples with a 0.45um pore size. The membrane is internally supported by an inert polyester web for dimensional stability, and the device pairs a 4.6 cm² effective filtration area with a low holdup volume to maximize sample recovery. Each filter is supplied nonsterile, in a yellow-coded acrylic housing, 500 per pack.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic, making it suitable for aqueous and alcoholic media without added wetting agents.
- Very low protein binding, supporting high recovery of proteinaceous solutions.
- Internally supported by an inert polyester web for dimensional stability and resistance to cracking or tearing.
- Broad pH compatibility (approximately 3 to 12) with chemical resistance to a variety of solvents.
- A 0.45um rating provides clarification and particulate removal ahead of analysis.
Key Construction Characteristics
- Ultrasonically welded acrylic housing, 33mm housing diameter, integrity tested to eliminate filter by-pass.
- Female Luer Lock inlet and Male Luer Lock outlet (Luer-Lok/Luer Lok) connections.
- Effective filtration area of 4.6 cm² with a holdup volume under 100 microliters.
- Maximum operating temperature of 50°C and maximum operating pressure of 80 psi.
- Nonsterile, supplied 500 per pack, with each filter labeled by membrane material and pore size.
The supported membrane structure maintains consistent flow and throughput across the run, reducing the number of filter changes during difficult filtrations. Low protein binding and low extractables help preserve sample integrity and keep analytical results clean. These attributes make the filter a dependable choice for routine clarification and chromatography sample preparation.
