Glass Schlenk Flask 50ml Borosilicate 0-4mm Vacuum Valve ADAMAS BETA

Description

Product Overview

The Glass Schlenk Flask offered by ADAMAS BETA is engineered for demanding laboratory environments where precision, durability, and chemical resistance are paramount. Constructed from high‑quality borosilicate glass, the flask provides a low coefficient of thermal expansion, ensuring stability under rapid temperature changes and reducing the risk of breakage during heating or cooling cycles. Its heavy‑wall design adds structural strength, allowing the flask to withstand the mechanical stresses associated with vacuum operations and repeated handling.

With a capacity of 50 ml, the flask is compact enough to fit into standard laboratory racks while still offering sufficient volume for a wide range of reactions, including small‑scale syntheses, distillations, and moisture‑sensitive procedures. The spherical shape promotes uniform heat distribution, which is essential for reactions that require precise temperature control. Integrated into the flask is a 0‑4 mm high‑vacuum valve, engineered to provide a reliable seal for air‑free manipulations, inert gas purging, and pressure‑controlled experiments.

Key specifications include:

• Material: Borosilicate glass with heavy‑wall construction
• Capacity: 50 ml
• Valve size: 0‑4 mm high vacuum valve
• Temperature resistance: Up to 500 °C (typical laboratory glassware limits)
• Compatibility: Suitable for use with standard Schlenk line accessories

Usage

This Schlenk flask is designed for chemists, researchers, and technicians who require a reliable container for air‑sensitive or moisture‑sensitive reactions. Its vacuum‑tight valve enables the removal of atmospheric gases, allowing the introduction of inert gases such as nitrogen or argon without exposing the reaction mixture to ambient air. This makes the flask ideal for organometallic syntheses, catalytic studies, and any procedure where oxygen or moisture could compromise product integrity.

In addition to vacuum applications, the flask can be employed in standard reflux setups, azeotropic distillations, and drying procedures. The transparent borosilicate glass provides clear visual access to the reaction mixture, facilitating real‑time monitoring of color changes, precipitate formation, or gas evolution. The heavy‑wall construction also offers enhanced resistance to thermal shock, enabling safe heating on oil baths, heating mantles, or direct flame when necessary.

Typical laboratory scenarios include:

• Glove‑box transfers where the flask is sealed and removed from the inert atmosphere
• Schlenk line operations for solvent drying and degassing
• Small‑scale organic syntheses that demand precise control of reaction atmosphere
• Educational demonstrations of vacuum techniques in university chemistry labs
