1) Description
Glass Fiber (GF) Membrane filters are made of glass fiber, featuring excellent thermal resistance, high filtration efficiency, and outstanding particle retention capability. Unlike traditional membrane filters, GF membranes have no fixed pore size but rely on their depth filtration structure, allowing them to capture both coarse and fine particles effectively.
These membranes are naturally hydrophilic, can withstand high temperatures, and are resistant to most organic solvents and strong oxidizers. GF membranes are particularly suitable for prefiltration of viscous or particulate-rich samples, effectively extending the service life of downstream membranes.
2)Features
▶ Depth filtration design – captures a wide range of particle sizes effectively.
▶ High flow rate and strong loading capacity for viscous or turbid samples.
▶ Excellent thermal stability.
▶ Compatible with most aqueous and organic solutions.
▶ Ideal for use as a prefilter to extend the life of finer membrane filters.
3) Application
GF membranes are widely applied in environmental monitoring, water and wastewater analysis, air sampling, food and beverage quality control, and biological sample preparation.
In laboratory and industrial workflows, they serve as ideal prefilters for membrane filtration systems, ensuring the accuracy of analytical results and protecting precision instruments from contamination.
