This product is developed for high-performance filtration in analytical chemistry and environmental monitoring, featuring a borosilicate glass microfiber matrix that provides superior retention of fine particles while maintaining rapid flow rates. The GC 50 grade offers thermal stability up to 500°C and low pressure drop, making it suitable for gravimetric analysis, air sampling, and prefiltration of aggressive solvents or acidic solutions. With a standard 110 mm diameter and 100-sheet packaging, it supports reproducible results in laboratory workflows requiring consistent pore structure and minimal extractables. Commonly used in stack testing, wastewater analysis, and pharmaceutical quality control, this filter paper balances mechanical strength with chemical resistance for reliable solid-liquid separation under both vacuum and pressure conditions.
