Excalibur 1230C-AW Granular Activated Carbon

Excalibur 1230C-AW is a virgin granular activated carbon produced from coconut shell char through a high temperature steam activation process under stringent quality control. It has a large surface area, high mechanical hardness, excellent pore volume and chemical stability that make it ideal for many liquid phase applications. Finally, the product is acid-washed to reduce ash and enhance purity.

Meets or exceeds all US Food Chemical CODEX standards. ANSI/NSF certified and California Prop 65 compliant.
