PALL 61631 A/E Glass Fiber Disc Filter - 1 µm, 47 mm (100/pkg)

The Pall 61631 A/E glass fiber filter is widely used for testing suspended solids in water and wastewater, air monitoring, and gravimetric analysis. It is ideal for applications that require high particle loading capacity and reliable filtration performance.

Glass fiber filters offer higher flow rates and greater dirt-holding capacity compared to many membrane filters. This makes them especially useful for dirty, viscous, or particle-heavy samples, where standard membranes may clog quickly.

No, the Pall A/E filters are made from binder-free borosilicate glass microfiber, which minimizes extractables and reduces the risk of contamination. This ensures clean, accurate analytical results, especially in sensitive testing.

These filters can tolerate very high temperatures (up to approximately 550°C), making them suitable for gravimetric analysis and high-temperature applications where other filter materials would degrade.

The 47 mm diameter is a standard size compatible with vacuum filtration systems, filter holders, and environmental monitoring setups. It is commonly used in laboratories and field testing equipment for consistent and repeatable results.
