Tokyo Glass Kikai (TGK) Charcoal Tube

This charcoal tube is a glass tube with an inner diameter of 6Φ mm filled with 20-40 mesh of activated carbon in two layers of 200mg / 400mg as a solid collector of organic solvent in the working environment, and both ends of the tube are sealed. Since the amount of activated carbon filled is larger than that of conventional charcoal tubes, it is suitable for sampling organic compound vapors that are particularly volatile, such as methyl bromide. It can also be used for sampling in the workplace where the saturation time is fast with the conventional charcoal tube.
