Volumetric flasks are commonly used in laboratories to accurately prepare fixed volumes of solutions, especially where high-precision solution preparation is required. They are designed so that users can accurately dilute or prepare solutions to a precise volume mark. Application Volumetric flasks are mainly used to accurately prepare standard solutions, such as preparing titrants in titration experiments, or preparing standard solutions with known concentrations in analytical chemistry. Typically, volumetric flasks are not recommended for long-term storage of solutions because their stoppers are not designed to provide a long-term seal like specialized storage bottles. The stopper of a volumetric flask is usually intended to provide a temporary seal during the preparation process, rather than to prevent long-term evaporation or contamination of the solution. However, in some cases, volumetric flasks can be used as temporary storage containers when no other containers are available or when the solution needs to be used within a shorter period of time. In this usage, it is important to ensure that the stopper maintains a good seal and that the solution does not react with the stopper material. If you need to store chemical solutions for a long time, it is more recommended to use specially designed storage bottles, such as brown narrow-mouth bottles or screw-top bottles, which usually have better sealing and protection against light, air and temperature changes. We can provide narrow-mouth bottles and wide-mouth bottles in various specifications to meet your experimental needs
