Reagenzröhrchen

A Reagenzröhrchen, commonly known as a test tube in English, is a thin-walled glass tube used primarily in laboratories for chemical reactions and biological assays. These cylindrical containers are open at one end and sealed at the other, typically with a rounded bottom to facilitate even heating and mixing of contents. Reagenzröhrchen are available in various sizes, ranging from small tubes for micro-scale experiments to larger ones for macro-scale procedures.

The material composition of Reagenzröhrchen is usually borosilicate glass, such as Pyrex, which offers high resistance to thermal shock and chemical corrosion. This makes them suitable for a wide range of applications, including heating, cooling, and storing substances. Some specialized versions are made from plastic or other materials to accommodate specific experimental needs, such as UV transparency or resistance to organic solvents.

Reagenzröhrchen are commonly used in chemistry, biology, and medicine for tasks such as mixing reagents, conducting precipitation reactions, or culturing microorganisms. They are often paired with a test tube rack or holder to keep them upright and stable during use. Additionally, they can be sealed with a stopper, parafilm, or a cap to prevent spills or contamination.

In modern laboratories, Reagenzröhrchen are frequently used in conjunction with other glassware, such as beakers, flasks, and pipettes, to facilitate precise and controlled experiments. Their simplicity and versatility make them a fundamental tool in scientific research and educational settings. Proper handling and disposal of Reagenzröhrchen are essential to ensure safety and minimize environmental impact.
