Description
The Erlenmeyer Flask with Ground Joint from Osmosis Scientific is high-precision laboratory glassware designed for advanced experimental applications where secure connections and controlled environments are required. Constructed from premium Boro 3.3 borosilicate glass, this flask provides superior resistance to chemical corrosion and thermal shock, making it ideal for research, synthesis, closed system reactions, and analytical workflows.
Its tapered conical body supports efficient mixing and swirling, while the ground glass joint allows secure, leak-resistant connections with condensers, adapters, reflux columns, and other glass components. This makes it especially suitable for reaction setups, reflux operations, distillation columns, and systems requiring tight glass-to-glass seals.
Graduations printed in durable white enamel provide convenient approximate volume reference for added usability during workflows. The flask’s robust base ensures stability on laboratory benches or heating platforms, while the borosilicate composition ensures durability through repeated heating, cooling, and sterilization cycles.
Available in a versatile range of capacities from 10 ml up to 2000 ml, this ground joint Erlenmeyer flask supports small-scale experimental setups as well as larger preparative tasks. Whether used in academic research, pharmaceutical labs, industrial R&D, or quality control settings, it delivers dependable performance, precision, and secure compatibility with glass assembly components.

Frequently Asked Questions (FAQs)
It is designed for heating, mixing, titrations, and synthesis reactions where a secure sealed or connected assembly is required; the ground joint allows direct attachment of condensers, adapters, still heads, and other standard laboratory accessories.
ASTM E‑438 specifies the requirements for borosilicate glass conical flasks, ensuring consistent dimensions, wall thickness, thermal resistance, and compatibility with standard jointed glassware across manufacturers.
Yes, borosilicate 3.3 Erlenmeyer flasks are safe for direct heating on hot plates or over burners, but gradual heating and cooling are recommended to minimize thermal stress.
Standard sizes include 14/20, 19/22, 19/38, and 24/40 (diameter/length in mm); size selection depends on flask capacity and compatibility with your condenser or adapter.
Erlenmeyer flasks with ground joints are typically offered from 10 mL up to 2000 mL or larger, supporting everything from small reactions to multi-liter batch preparation and distillation work.
