Glass Microfiber Filters

Glass microfiber filters are specialized filter media widely used in laboratories and industrial processes for air and liquid filtration. These filters are renowned for their high loading capacity and fine particle retention, making them particularly effective for critical applications such as environmental testing, water analysis, and air pollution monitoring.

Made from 100% borosilicate glass, these filters possess inherent resistance to chemical attack and can withstand high temperatures, which is essential for operations requiring sterilization or incineration post-use. The structure of the glass microfiber material enables fast flow rates while maintaining high efficiency in trapping fine particulate matter. This makes them suitable for capturing airborne contaminants, clarifying liquids, and even collecting precipitates in biochemical assays.
