How It Is Used
A solid is dried in the open bottle, the stopper is fitted, and the closed bottle is weighed so the sample cannot take up moisture from the air or lose mass on the balance. It is used in analytical chemistry, quantitative analysis and pharmaceutical work.
Frequently Asked Questions
Why use the Weighing Bottle for hygroscopic samples?
Its ground-glass stopper closes the bottle, so the sample cannot absorb atmospheric moisture or lose mass while it is being weighed.
Laboratories and education suppliers in Japan, Botswana, Costa Rica, Bulgaria and Sierra Leone can source the Weighing Bottle from JLab India for export.
