Bulk Pack of Brown volumetric flask

A brown volumetric flask is a type of laboratory glassware designed for precise measurement of a specific volume of liquid. It is made of transparent brown glass, which provides protection against light-sensitive substances or reactions. Volumetric flasks typically have a narrow neck and a flat-bottomed flask body with a single marking indicating the calibrated volume. They are commonly used in analytical chemistry and scientific research to prepare accurate and standardized solutions where the volume needs to be precisely controlled. The brown color of the flask helps to minimize the influence of light on the contents inside.

棕色容量瓶是一種實驗室玻璃器皿，用於精確測量特定體積的液體。它由透明的棕色玻璃制成，可防止對光敏感的物質或反應。容量瓶通常有一個狹窄的瓶頸和一個平底瓶身，瓶身上有一個指示校准容量的標記。它們通常用於分析化學和科學研究，以制備需要精確控制體積的精確標准化溶液。燒瓶的棕色有助於最大限度地減少光線對瓶內物質的影響。
