Description of 0.45 Micron Glass Fiber Filters

Glass Fiber is a material made up of numerous extremely fine fibers of glass, the simple, pure, and acrylic binder-free line of borosilicate glass fiber membrane. This media integrates porous polymer materials (plastics and fiber) with microfiber glass, synchronizing the excellent strength of polymers with a variety of fiberglass functions as well as eliminating acrylic binders that could pose the risk of potential contamination.

Hawach has two types, one is standard like Whatman GF/C, microporous glass fiber membrane filter without binder, another one is the domestic type, it is glass fiber with the binder.

Glass fiber membrane filters have the properties of fast flow rate and high load capacity. Microporous membrane filter is suitable for pre-filter paper, which greatly increases the particle load capacity of the filter. Another membrane that can be used as a pre-filtration is polypropylene membrane, which is the same as glass fiber membrane filters and used at the front end of membrane filtration to prevent filter clogging. Same as the PTFE membrane filter, glass membrane filter also is a hydrophobic membrane filter.

Hydrophobic membrane filter 47mm is widely used in daily air monitoring and special monitoring of solid pollutants, microorganisms, oil, and acid mist in the air. Glass fiber membrane filter is especially recommended for the collection of high-efficiency fine particles.
