2） Product Overview

Glass Fiber (GF) membrane filters are fabricated from glass fiber media with superior heat resistance, high filtration efficiency and powerful particle interception capacity.
Different from conventional flat-sheet filter membranes, GF adopts a depth filtration structure without a single fixed pore size, which efficiently traps both large coarse particles and tiny fine particulates.
The membranes are inherently hydrophilic, withstand high temperatures, and resist most organic solvents and strong oxidizing agents.
GF filters excel at pre-filtering viscous or high-particulate samples, greatly prolonging the service life of precision downstream filter membranes.

3） Key Features

• Depth filtration structure: Efficiently intercept particles of various sizes
• Fast flow rate and high dirt-holding capacity, perfect for viscous and turbid liquid samples
• Outstanding thermal stability under high-temperature working conditions
• Compatible with most aqueous and organic solvent systems
• Excellent pre-filter medium to reduce clogging and extend the lifespan of fine-pore final membranes

4） Applications

GF glass fiber membranes are extensively used in environmental monitoring, drinking water & wastewater testing, air particulate sampling, food & beverage quality inspection and biological sample pretreatment.
In laboratory and industrial filtration workflows, they act as ideal pre-filters for full membrane filtration systems, securing accurate analytical data and preventing precision analytical equipment from particulate contamination.
