Mätkolvar

Mätkolvar, also known as volumetric flasks, are laboratory glassware used to accurately measure a specific volume of liquid. They are typically tall, slender flasks with a round, flat bottom and a long neck. A single calibration mark etched onto the neck indicates the precise volume the flask is designed to hold at a specific temperature, usually 20 degrees Celsius. Mätkolvar are characterized by their high degree of accuracy, making them indispensable for preparing solutions of precise concentrations.

The primary use of a mätkolv is in quantitative chemical analysis, where exact measurements are crucial. To use a mätkolv, a solute is typically dissolved and then diluted to the calibration mark using a solvent. This process ensures that the final volume of the solution is known with high precision. Mätkolvar come in various sizes, ranging from a few milliliters to several liters, and are usually made of borosilicate glass to withstand temperature changes and chemical reactions. They are essential tools for chemists, biochemists, and other scientists requiring accurate volumetric measurements for experiments and analyses.
