Carbon Beads Active Sampling Tube

Features：

This gas sampling tube for non-polar organic solvents uses synthetic petroleum carbon beads as adsorbents.

This product is a tube containing two layers of 20-40 mesh carbon beads, with the front layer weighing 100 mg and the back layer weighing 50 mg.

It contains two beds of the same selective adsorbent separated by glass wool or foam.

Dual-layer or two-bed construction of the tube allows for any sample breakthrough to be captured in the smaller back-up bed.
