Test tubes and funnels are instruments used to mix and filter small amounts of samples such as liquids and powders. Test tubes have a U-shaped closed-bottom end. They are mainly used in experiments to observe changes in the state of substances and chemical reactions. They can withstand not only flames of gas burners, but also heat of autoclaves. Funnels are conical, elongated tubes. They are used when transferring liquid or powder from a container with a large diameter to a small container or when filtering. They are also called JOGO in Japanese. The material is glass, clay, PP, PFA, etc. In addition to the usual triangular funnels, there are separatory funnels and Büchner funnels. In addition, there are test tube holders that hold test tubes, centrifuge tubes used in centrifuges, and Spitz tubes.
