General description

ORBO sorbent tubes (matrix Carboxen^® 1000, ORBO tube I.D. × L 6 mm × 95 mm, Bed B 90 mg, Bed A 180 mg, 60/80 mesh) 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.
