Bulk Pack Volumetric flask

volumetric flask is a laboratory glassware designed to accurately measure and hold a specific volume of liquid. It has a flat bottom, a long neck, and a narrow opening. Volumetric flasks are calibrated to contain a precise volume at a specific temperature, typically at 20 degrees Celsius. They are used in analytical chemistry and other scientific fields for preparing solutions with precise concentrations. The volume is indicated by a graduation mark on the neck of the flask. Volumetric flasks have a stopper or cap to maintain the contents and prevent evaporation or contamination. 

容量瓶是一種實驗室玻璃器皿，用於精確測量和盛放特定體積的液體。它有一個平底、長頸和窄口。容量瓶經過校準，在特定溫度（通常為 20 攝氏度）下可容納精確的體積。它們用於分析化學和其他科學領域，配制濃度精確的溶液。容量由燒瓶頸部的刻度標記表示。容量瓶有一個瓶塞或瓶蓋，用於保持瓶內的液體，防止蒸發或污染。
