Product Description

Our specific gravity bottles with glass/PTFE stopper are precision laboratory vessels designed for accurate density determination and specific gravity measurements. These bottles feature a combined glass and PTFE stopper design that provides exceptional durability, chemical compatibility, and long-term reliability.

The glass component of the stopper ensures precise fit and sealing with the bottle's ground neck, while the PTFE (polytetrafluoroethylene) component provides superior chemical resistance and compatibility with a wide range of solvents and solutions. This hybrid design combines the precision of traditional ground glass stoppers with the enhanced chemical durability of PTFE.

Each bottle features individually specified tolerance ranges, ensuring accurate volume measurement and reliable density calculations. The precision construction and careful manufacturing processes guarantee consistent results across multiple measurements and applications.
