[Features] By passing gas through two nozzles at the top, the substance is absorbed into the liquid or granules inside the bottle. It can be used to increase the purity of gas by adsorbing unnecessary substances, or to collect substances absorbed in the internal liquid. The spherical gas foaming section has a hole of φ1 mm on the side, which allows a certain amount of ventilation even with a relatively large amount of gas. Since it uses parts that are common to screw-cap cleaning bottles, it is easy to disassemble and clean.
