Product parameters

Product Name Quartz Three-Neck Round-Bottom Flask
Material High-Purity Fused Silica (Quartz Glass)
Key Features

  • Excellent high-temperature resistance and superior thermal shock stability for demanding reactions.

  • High chemical purity and inertness, ensuring no interference with experimental processes.

  • Features three standard taper ground glass joints, allowing for multiple simultaneous connections and complex setups.

  • Robust construction with uniform wall thickness for durability; good optical clarity for visual monitoring.
Applications

An essential piece of laboratory glassware designed for complex chemical syntheses and reactions that require multiple apparatus connections. The three-neck configuration is ideal for:

  • Simultaneous operations such as stirring, refluxing (with a condenser), addition of reagents (via dropping funnel or addition funnel), and temperature monitoring.

  • Versatile setups in organic synthesis, distillation, and other advanced laboratory procedures.

  • Applications requiring high thermal stress resistance, chemical inertness, and the ability to connect multiple components securely.
