Carbon Beads Active Tube, Jumbo Type, box of 12

This product consists of a glass tube filled with cleaned carbon beads (activated carbon beads) collected in two layers, and sealed. Because this product has the larger filling amount of activated carbon beads than that of activated carbon beads, standard type (100 mg + 50 mg), it is particularly suited for sampling volatile organic compound vapor and it can be used for long term sampling. Moreover, thanks to a two-layer system, it is possible to judge the breakthrough amount at the time of measurement. The glass tube has been subjected to precutting processing to make it easy to snap.
