❓ Q&A: Focus on Airtight Seal and Material Integrity

Q1: Why is borosilicate glass superior for weighing bottles?

A: **Borosilicate glass** offers high chemical resistance and low thermal expansion, meaning the bottle's mass (tare weight) remains constant even with minor temperature fluctuations, ensuring maximum accuracy during high-precision **weighing procedures**.

Q2: What is the main purpose of the ground glass stopper?

A: The ground glass stopper ensures a perfect fit, creating a sealed, **airtight environment**. This seal prevents moisture from the air from affecting hygroscopic samples, eliminating significant sources of weighing error in **analytical labs**.
