Description
A Schlenk Reaction Flask with a built in stopcock provides precise control during air sensitive and moisture sensitive chemistry, allowing researchers to switch between vacuum and inert gas environments with accuracy. Manufactured from high clarity LabChoice BORO 3.3 glass, the flask delivers strong chemical durability, low thermal expansion, and excellent thermal shock resistance in line with ISO 3585 and ASTM E438 Type I requirements.
The integrated stopcock enables secure evacuation, gas purging, solvent degassing, and reagent handling without exposing materials to atmospheric oxygen or humidity. Its precision ground single neck joint supports leak free sealing for reflux, inert transfers, low temperature reactions, and catalytic processes. The uniform wall thickness and high temperature stability allow repeated heating cycles and flame sealing, making it ideal for Schlenk line operations, glovebox workflows, and advanced synthesis tasks.
Designed for Australian universities, research laboratories, and industrial chemistry groups, this Schlenk flask ensures dependable performance during demanding reaction setups. LabChoice Australia supplies multiple capacities to suit routine laboratory synthesis through to complex multi step procedures, supporting consistent, reproducible, and contamination free results across a wide range of chemical applications.
