Bottle Reagent with hollow stopper (Quartzware)

The Quartzware Reagent Bottle with Hollow Stopper is a premium laboratory-grade container made from high-purity fused quartz (≥ 99.99% SiO₂), designed for the safe storage and dispensing of volatile, corrosive, or ultra-pure chemical reagents. This precision-engineered bottle ensures chemical inertness, optical clarity, and superior thermal resistance, making it ideal for use in high-temperature, cleanroom, or UV-sensitive applications. The low-expansion, heat-resistant quartz body is paired with a matched hollow-ground quartz stopper, providing an airtight seal that prevents contamination and evaporation while allowing minimal pressure exchange. The hollow stopper design helps equalize temperature or pressure variations, reducing the risk of cap displacement or vacuum lock during heating or cooling. Each bottle is fire-polished, stress-relieved, and carefully annealed for mechanical durability and dimensional stability.
