SK1 8x30
Filtracarb® SK1 8x30 is a granular activated carbon manufactured from specially selected grades of coal by a steam activation process.
The material is manufactured under stringently controlled conditions to produce an extremely porous adsorbent with a highly developed internal surface area.
- Versatile liquid phase adsorbent
- Maximised internal pore volume
- Highly developed internal surface area
- Optimum adsorption kinetics
- Conforms to USA CODEX
- Supplied to BS EN ISO 9001:2008
