Our hardened low ash filters demonstrate high wet strength and chemical resistance and have a hardened and highly-glazed surface that can withstand wet handling and scraping.
They are particularly suitable for Büchner filtration where the tough smooth surface of the filter makes it easy to recover precipitates.

Acid-washed and rinsed with water to neutralise
Free of minerals, ideal for the detection of metallic ions
Applications
