kémcsövet

Kémcső is a Hungarian term that translates to "test tube" in English. It refers to a common piece of laboratory glassware characterized by a cylindrical shape with a rounded or flattened bottom and an open top. Kémcsövek are typically made of glass, though plastic versions are also available for specific applications. Their primary use is to hold, mix, and heat small quantities of liquid or solid chemicals during experiments or analyses.

The size and shape of kémcsövek can vary depending on their intended purpose. Smaller, thinner-walled kémcsövek are often used for qualitative tests and observations, while larger, thicker-walled ones are employed for heating or reactions that require more robust containment. The open top allows for easy addition and removal of substances and for the insertion of stoppers or other closures when necessary.

Kémcsövek are fundamental tools in various scientific disciplines, including chemistry, biology, and medicine. They are indispensable for tasks such as titrations, colorimetric analysis, culture growth, and the preliminary examination of samples. The ease with which they can be cleaned and reused makes them a cost-effective and practical choice for laboratories worldwide. Their simplicity belies their importance in facilitating a vast array of scientific investigations and discoveries.
