General description

ORBO 555 LpDNPH 300/150 mg sorbent tubes (W,W,W separators, O.D. × L. 6 mm × 105 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.
