Premium borosilicate glass standing flasks: Temperature-resistant, acid- and chemical-resistant.

Standing flask made of borosilicate glass 3.3

•    Temperature resistant up to +250 °C
•    Resistant to acids, alcohols, and chemicals, except hydrofluoric acid and concentrated alkaline solutions.
•    Can be autoclaved and sterilized.

Purpose-specific Uses

With a cork stopper: decorative and hygienic dispenser for peanuts or aperitifs
As a water or wine carafe
As a sight glass
With a wide neck: used as a drinking glass

Unlike round-bottomed flasks, vertical flasks—also known as stand-up or titration flasks—have a flat base and do not require a stand. Their bulbous shape and even wall thickness allow for uniform heating of the contents. The nearly round shape ensures efficient mixing when swirling, and the narrower neck reduces the risk of liquid spillage compared to beakers.
However, hip flasks should not be placed under vacuum, as their flat base makes them prone to implosion. They can be sealed effectively with cork or rubber stoppers.
