Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Lok, Sterile, 50/Pk Images
Featuring a hydrophilic cellulose acetate membrane internally supported by an inert polyester web, this sterile 13mm syringe filter delivers fast, clean clarification of aqueous and organic samples with very low protein binding. The 0.45um pore size removes particulates ahead of analytical instrumentation, while the modified acrylic housing bidirectionally supports the membrane to allow either sample injection or aspiration. Each unit provides a 0.76 cm² effective filtration area and a holdup volume under 50 microliters to preserve precious sample, and ships sterile in packs of 50.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic, making it suitable for aqueous and organic samples without pre-wetting.
- Very low protein binding to maximize recovery of proteins, enzymes, and biological solutions.
- Internally supported by an inert polyester web for exceptional wet strength and dimensional stability.
- Chemical resistance to a wide variety of solvents across an approximate pH range of 3 to 12.
- 0.45um pore size for reliable clarification and particulate removal.
Key Construction Characteristics
- Modified acrylic housing, ultrasonically welded and integrity tested to eliminate filter by-pass.
- 13mm membrane diameter with an 18mm housing diameter and 0.76 cm² effective filtration area.
- Female Luer Lock inlet and Male Luer Lock outlet for secure syringe connections.
- Holdup volume under 50 microliters; maximum operating temperature 50°C (122°F); maximum operating pressure 80 psi.
- Supplied sterile, color-coded yellow, in packs of 50.
This filter maintains sample integrity by combining a low binding membrane with a rugged, leak-resistant housing. The supported cellulose acetate structure withstands handling pressure without cracking or tearing, providing consistent flow and dependable particulate removal. The result is a clarified sample ready for downstream chromatography or biological work.
