The neutral hard glass test tube, size 18x150 mm, is a laboratory container made from neutral glass, widely used for holding, mixing, heating, and storing liquids or solids during experiments. These test tubes are cylindrical with a rounded bottom and an open top, made from neutral soda-lime glass that resists moderate temperature changes and chemical interactions. They have a wall thickness typically between 0.8 and 1.2 mm and are known for their mechanical strength and chemical stability. Commonly available in packs of 100, these tubes are suitable for general laboratory use including research, pharmaceutical, educational, and industrial applications. Neutral glass tubes do not affect the pH of their contents and provide clear visibility for precise observation.
