The simplest type of chemical laboratory equipment. It is generally a glass tube with one end closed and a round bottom. It is used as a preliminary experimental container for operations such as dissolving, heating, and cooling small amounts of chemicals, and for observing color reactions and precipitation reactions, and is also used for culturing bacteria. It is also useful as a storage container. Special types include those with stoppers and graduated marks, and those made of colored glass, metal, or synthetic resin.

もっとも簡便な化学実験器具。ガラス管の一端を閉じて丸底にしたものが一般的である。少量の薬品を用いた溶解、加熱、冷却などの操作、呈色反応、沈殿生成反応などの観察等、予備実験容器として使われ、細菌の培養などにも利用される。保存容器としても便利である。特殊なものとして、共栓付き、目盛り付き、着色ガラス製、金属製、合成樹脂製のものなどもある。 [岩本振武] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
