Advantages
Heat Resistance up to +500 °C
Withstands high temperatures without cracking or deformation — suitable for heating and autoclaving.
Graduated Scale
Clear markings on the flask wall allow quick and accurate volume measurement of laboratory solutions.
Ground Glass Stopper
Provides a tight, leak-free seal without the need for additional sealing materials.
Applications
Hermetic Sealing
Ideal for reactions under inert atmosphere and for storing volatile substances — no vapor or gas exchange.
Material Uniformity
Stopper and flask are both made from borosilicate glass, ensuring equal thermal expansion and structural integrity.
No Lubricant Required
No need for PTFE or petroleum jelly — the ground joint seals reliably when clean and used properly.
Long Service Life
With proper care (rinsing, gentle storage, occasional ethanol mist), ground joints last for years without damage.
