Glass Distilling Flasks

Each flask is blown from high-quality, low-expansion borosilicate glass to ensure exceptional thermal shock resistance. The integrated long glass sidearm is positioned at a precise downward angle to facilitate a seamless connection with standard glass condensers (such as Liebig or West columns). With a round-bottom design that promotes uniform heat distribution and a structurally reinforced neck, these flasks deliver dependable, long-term durability under continuous boiling parameters.

Key Functional Benefits:

• Precision-Angled Sidearm: The extended glass side-delivery tube ensures reliable condensate routing into downstream cooling elements, minimizing vapor leaks and pressure bottlenecks
• Uniform Wall Thickness: Blown with uniform glass distribution to prevent thermal hot spots, drastically reducing the risk of structural fractures or thermal stress failure
• Low-Expansion Borosilicate Composition: Withstands rapid thermal transitions and intense heating cycles from Bunsen burners or specialized heating mantles
• High-Visibility Markings: Outfitted with large, high-contrast white block lettering for rapid, error-free capacity identification on crowded inventory shelves
