Charcoal Sorbent Tube / standard / 24 pcs,・ The tube is filled with two layers weighing 50 mg and 100 mg of 20-40 mesh activated charcoal, which is highly adsorbent with respect to many nonpolar organic solvents.

・ There are two layers, so breakthrough determinations are possible during measurement.

・ This is compliant with the Japanese Working Environment Measurement Act and NIOSH.

・ The glass tube has been pre-scored to make it easier to cut.,

,

Charcoal Sorbent Tubes / single layer / 24 pcs,・ A single layer of washed activated charcoal (sorbent) is enclosed in a glass tube. (200 mg of 20-40 mesh activated charcoal)

・ It is used in the same way as the standard model, and is convenient when the backup second layer of activated charcoal is not necessary.

・ The glass tube has been pre-scored to make it easier to cut.,

Carbon Beads Active Sampling Tube / 24 pcs,This gas sampling tube for nonpolar organic solvents uses synthetic petroleum carbon beads as the sorbent. Connect it to a suction pump, perform solvent extraction of the collected substances, and analyze them using gas chromatography. This has better adsorption and desorption than coconut shell carbon, as well as favorable storage functionality after collection. This product is a tube filled with two layers of 20-40 mesh carbon beads, the front layer weighing 100 mg, and the back layer weighing 50 mg. Since there are two layers, the amount of breakthrough during measurement can be determined.,
