Koeputkiin

Koeputkiin is a Finnish term that translates to "test tube" in English. It refers to a cylindrical glass or plastic tube used in laboratories for holding, mixing, or heating small amounts of liquid. These tubes are a fundamental piece of equipment in various scientific disciplines, including chemistry, biology, and medicine.

The typical koeputki is open at one end and closed at the other, often with a rounded or conical bottom. They come in a wide range of sizes, from a few milliliters to several hundred milliliters, and are made from materials that can withstand different chemical reactions and temperatures. Some koeputkiin are designed to be heated directly over a flame, while others are used for non-heating applications like sample collection or storage. The material used, commonly borosilicate glass, offers resistance to thermal shock and chemical corrosion. Plastic alternatives are also available for specific uses where breakage is a concern or for disposability.

The versatility of the koeputkiin makes it indispensable for a multitude of laboratory procedures. This includes conducting chemical reactions, observing biological samples, performing titrations, and storing specimens. Their simple yet effective design has remained largely unchanged for decades, highlighting their enduring utility in scientific research and diagnostics.
