Glass weighing bottles

Introduction to Glass weighing bottles

Glass weighing bottles are laboratory labware used to hold and determine sample mass on analytical balances, while minimizing moisture absorption or evaporation during handling. This labware is typically equipped with a ground-glass airtight stopper, protecting solid or liquid samples from degradation or weight changes throughout the weighing and drying processes.

When selecting glass weighing bottles, buyers should consider the bottom dimensions, height, or volume suitable for the balance chamber and the sample amount to be analyzed. Hoa Viet currently distributes glass weighing bottles from Assistent (Germany) with dimensions 35x30mm, 40x25mm, 50x30mm, 60x30mm, 80x30mm and from Kimble-DWK (USA) with a capacity of 35ml. Depending on the specific experimental procedure, customers can contact Hoa Viet for assistance in selecting the appropriate specifications.

For what purposes are glass weighing bottles used?

This labware is mainly used to hold samples during quantitative weighing on analytical balances, especially for hygroscopic or volatile chemicals. In addition, weighing bottles are also used in moisture determination drying tests or for temporary sample storage in desiccators.

Which brands of glass weighing bottles does Hoa Viet provide?

Currently, Hoa Viet distributes glass weighing bottles from two brands: Assistent (Germany, EU origin) and Kimble-DWK (USA).

How to choose the appropriate specification of glass weighing bottles?

Users should base their choice on sample mass, working volume, and the balance pan area of the weighing chamber. The portfolio offers dimensions such as 35x30mm, 40x25mm, 50x30mm, 60x30mm, 80x30mm, or volume 35ml to meet specific requirements.

What should be noted when handling and storing glass weighing bottles?

Operators should use tongs or wear gloves to prevent grease and sweat from adhering to the bottle walls, which can cause weighing errors. The weighing bottle and ground stopper must be thoroughly cleaned, completely dried, and tightly closed when transferring samples between analytical areas.
