ORBO Sorbent Tubes For Gas & Vapor Sampling

ORBO sorbent tubes contain two beds of the same selective adsorbent seperated by glass wool or foam, for gas and vapor sampling. The dual-layer or two-bed construction of the tube allows for any sample breakthough to be captured in the smaller back-up bed. Our sorbent tubes contain Supelco′s high quality adsorbents that professionals world-wide trust for their applications.
