Our glass flask is manufactured from premium borosilicate glass, featuring excellent thermal stability and chemical resistance to acids, alkalis and organic solvents. Available in round-bottom, flat-bottom and volumetric styles, it comes with clear graduations or standard ground joints for secure connections. Ideal for liquid mixing, heating, chemical reactions and volume calibration, it is widely used in laboratory research, educational experiments, pharmaceutical production and chemical processing, delivering reliable performance for diverse lab operations.
1. Crafted from premium borosilicate glass, our glass flasks deliver exceptional thermal and chemical stability, withstanding temperatures from -20℃ to 150℃. The wall thickness tolerance is controlled at ±0.1mm, making this laboratory glass flask highly resistant to cracking and corrosion in long-term lab operations.
2. Our volumetric glass flask features laser-engraved graduations calibrated to ISO 4788 standards, with a volume measurement error as low as ±0.05%. The clear, fade-resistant markings ensure precise liquid calibration, making it an indispensable laboratory glass flask for accurate solution preparation and analytical testing.
3. Engineered for practicality, our glass flasks integrate a narrow, uniform neck and a stable flat base to prevent tipping. The standard ground glass joint ensures a tight seal with other lab apparatus, while the smooth inner surface simplifies cleaning, supporting repeated use in diverse experimental workflows.
4. Each laboratory glass flask undergoes 100% strength and leak testing, with a finished product pass rate exceeding 99.8%. The reinforced glass structure reduces breakage risk, and the material’s non-porous nature avoids sample adsorption, guaranteeing the reliability of experimental results for glass flasks in routine and critical applications.
Our glass flask is ideal for heating and mixing chemical reagents, with excellent thermal stability. It supports reflux, synthesis, and decomposition experiments, widely used in organic and inorganic chemistry labs for reliable reaction control.
Suitable for storing liquid samples and microbial culture, its narrow neck reduces contamination risk. The transparent borosilicate glass allows clear observation, making it perfect for biology, microbiology, and environmental sample preservation.
Volumetric glass flask ensures precise liquid volume calibration for standard solution preparation. With clear, durable graduations, it meets analytical chemistry requirements in pharmaceutical, food, and environmental testing labs.
Place the flask on a stable, heat-resistant surface. Add liquids or solids gradually, avoiding overfilling—leave sufficient headspace for mixing or heating. For heating, use a water/oil bath or heating mantle; never heat empty. Swirl gently for mixing, and seal with a stopper if needed to prevent contamination or evaporation.
