Welded GF+PTFE Syringe Filter

1) Description

This welded GF+PTFE syringe filter features a three-layer membrane structure consisting of a polypropylene (PP) prefilter, a glass fiber (GF) intermediate layer, and a high-performance final PTFE Hydrophilic/Hydrophobic membrane. Designed to handle samples with high particulate loads or high viscosity, it ensures efficient filtration and extended membrane life, making it ideal for demanding sample preparation applications.

2)Features

• Welded construction without adhesives ensures high chemical purity during filtration.
• Triple-layer design significantly increases dirt-holding capacity and reduces clogging risk.
• The PP membrane serves as a coarse prefilter, effectively capturing large particulates and improving filtration speed.
• Glass fiber intermediate layer provides depth filtration, enhancing throughput and protecting the final membrane.
• Available with various final membrane materials (e.g., Nylon, PES, PTFE) to meet specific chemical compatibility and hydrophilic/hydrophobic requirements.
• High-strength housing offers excellent pressure resistance and fits standard syringes or liquid-handling systems.
• Available in sterile or non-sterile versions to suit laboratory and industrial applications.

3) Applications

• Ideal for sample preparation in HPLC, GC, and ICP analysis.
• Recommended for filtration of serum, culture media, tissue homogenates, and other viscous or particle-rich biological samples.
• Widely used in environmental monitoring, food safety testing, pharmaceutical analysis, and general laboratory filtration tasks.
