General description

ORBO 78 HBR on Carboxen® 564 specially cleaned (20/45), 400/200 mg sorbent tubes (W,W,W separators, O.D. × L 6 mm × 110 mm) contain two beds of the same selective adsorbent separated by glass wool or foam, for gas and vapor sampling. The dual-layer or two-bed construction of the tube allows for any sample breakthrough to be captured in the smaller back-up bed.
