Fritz Pro Carbon AG (Activated Granular) 226 gr.

Produced from bituminous coal by a high-temperature activation process under stringent quality control. Fritz uses a special, patented, high-pressure steam activation process that produces superior pore space throughout each individual granule. The carbon is then washed in hydrochloric acid to reduce water and acid-soluble compounds and improve purity. This treatment creates the porosity by leaving a carbon skeleton sponge. It has a large surface area (each ounce contains over 300,000 square feet of usable, adsorptive surface area), high mechanical hardness, high pore volume and chemical stability.
