Description
Gastec 258S2-20 Activated carbon tube
Gastec 258S2-20 Activated carbon tube The activated carbon tube is used in work environments where organic-solvent vapour is collected. Generally the activated carbon tube is suited for detection of almost all organic solvents of low polarity .
Gastec 258S2-20 is a single-layer, spherical bead-shaped activated charcoal sorbent tube used for collecting airborne organic solvent vapors and low-polarity Volatile Organic Compounds (VOCs).
The key distinction of the 258-series compared to standard granular charcoal tubes (like the 251-series) is the use of bead-shaped (spherical) activated carbon. This spherical morphology provides more uniform packing, lower airflow resistance, and consistent adsorption performance during continuous air sampling.
