Tailored for chemical labs, our 20ml heat resistant glass ampoules blend durability, safety, and practicality – the perfect choice to store, mix, or heat experimental reagents.

20ml volume fits most chemical experiment scenarios – from small-batch reagent storage to moderate-volume reaction mixing. Eliminates frequent refilling, boosting your lab efficiency.

Crafted from heat-resistant borosilicate glass, it withstands sudden temperature changes (from -20°C to 300°C) and direct heating (e.g., water bath, hot plate). No cracking or deformation – keeps your experiments secure.

• Sealed neck: Melts easily to lock in volatile/oxidizable reagents, preventing contamination or evaporation.
• Clear glass: Lets you monitor reagent color, state, or reaction progress at a glance.
• Smooth surface: Easy to label (with lab markers) for reagent identification, avoiding mix-ups.

Every ampoule undergoes strict testing for heat resistance, thickness uniformity, and leakage. Ensures consistent performance – no unexpected failures ruining your experiments.

The 20ml clear amber glass ampoule is a versatile and high-quality packaging solution that offers protection and preservation for a wide range of liquid products across different industries. The clear aspect of the glass allows for easy visibility of the contents, while the amber color provides additional protection from light-induced degradation.

Jingu eatablished in 1988, 34 years of professional glass vial and ampoule manufacturing experience.

The tubing factory is equipped with advanced equipment and technology for the production of high-quality glass tubing. The factory uses high-quality raw materials and advanced manufacturing processes to ensure the consistency and quality of the glass tubing produced.
