Weighing bottles are a common type of laboratory glassware. They are typically used to prepare and weigh a certain amount of solids. They are small glass containers used for accurately weighing analytical samples. They are typically cylindrical in shape with a ground-fit cap. Cylindrical glass bottles with ground-fit stoppers are used for differential weighing of samples.
The ground-fit stopper prevents the sample from absorbing moisture and CO2 from the air, making them suitable for weighing hygroscopic samples.
