When you're working with compounds that can't tolerate even a trace of oxygen or moisture, ordinary lab glassware just won't cut it. That's where the Schlenk reaction flask truly shines—a specialized piece of equipment designed specifically for handling air-sensitive materials in vacuum environments.
Crafted from high-quality borosilicate glass, this reaction tube features a heavy-wall construction that gives it superior thermal resistance. The low coefficient of thermal expansion means it can withstand rapid temperature changes without cracking or warping, making it ideal for experiments involving heating, cooling, or temperature cycling.
The pear-shaped design isn't just for aesthetics—it serves a practical purpose. The unique shape promotes better mixing and more efficient heat distribution during reactions. The uniform wall thickness ensures consistent performance, while the exceptional transparency allows you to monitor reaction progress without interrupting the process.
What truly sets this flask apart is the integrated PTFE stopcock. Unlike standard glass stoppers that can seize or leak, the PTFE (polytetrafluoroethylene) valve provides smooth, reliable operation with excellent chemical resistance. The 19/22 joint ensures compatibility with standard laboratory apparatus, making it easy to integrate into your existing setup.
Whether you're conducting organometallic synthesis, working with pyrophoric materials, or performing reactions under inert atmosphere, this Schlenk flask becomes an indispensable part of your laboratory workflow. Its professional-grade construction and thoughtful design details make it a favorite among chemists who demand precision and reliability in their glassware.
