MilliporeSigma™ Supelco™ ORBO™ 100 on Carbotrap B (20/40), 350/175 mg W,W,W separators

Description

ORBO™ sorbent tubes (W,W,W separators, O.D. x L 7 mm x 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.
