1) Description
This welded GF+CA syringe filter adopts a three-layer membrane structure, consisting of a polypropylene (PP) prefilter, a glass fiber (GF) intermediate layer, and a cellulose acetate (CA) final membrane.
It is specifically designed for aqueous sample filtration where low protein binding and high flow rate are required. The GF layer provides efficient depth filtration for samples with high particulate content, while the CA membrane ensures excellent filtration precision and sample recovery.
The all-welded design eliminates adhesive contamination, making it ideal for biological, pharmaceutical, and environmental testing applications that demand high purity and reliability.
2)Features
- Welded construction eliminates adhesive contamination, ensuring high filtration purity.
- Triple-layer structure combines prefiltration and depth filtration, increasing sample throughput.
- CA final membrane provides low protein binding, high flow rate, and excellent hydrophilicity, ideal for aqueous samples.
- GF layer effectively captures suspended particles, protecting the CA membrane and extending service life.
- Chemically compatible with most neutral and weakly acidic aqueous solutions; recommended for biological and analytical filtration.
- Strong housing design withstands high operating pressure and fits standard syringes or automated systems.
- Available in sterile and non-sterile versions for flexible laboratory and industrial applications.
3) Applications
- Suitable for aqueous biological samples such as protein solutions, buffers, serum, and cell culture media.
- Recommended for HPLC, ion chromatography, and general analytical sample preparation.
- Ideal for pharmaceutical testing, environmental water analysis, and food and beverage quality control.
- Effective for removing fine particulates and protecting analytical instruments.
