Receiver Adapter, Straight, with Vacuum Connection

[table id=576 /]

The GISCOM Receiver Adapter, Straight, with Vacuum Connection, is a precision-engineered glass connector used to link condensers, flasks, and distillation units while enabling controlled vacuum application. Its straight design ensures unobstructed flow, and the integrated side vacuum outlet supports efficient solvent removal and pressure regulation. This adapter is essential in distillation, reduced-pressure processes, and analytical workflows where reliable vacuum control is critical.

Key Features

• Straight, unobstructed flow path for smooth transfer of distillate.
• Integrated vacuum connection for secure tubing attachment and stable vacuum control.
• Precision-ground, standardised joints ensure perfect compatibility with international glassware systems.
• Manufactured from premium Borosilicate Glass 3.3 for excellent durability, thermal shock resistance, and chemical inertness.
• Clear visibility for monitoring liquid passage and flow behaviour.
• Leak-proof design suitable for low-pressure and high-purity applications.
• Ideal for distillation, solvent recovery, and vacuum-assisted operations.

Handling & Precautions

• Inspect for chips or cracks before use, especially around ground joints and the vacuum sidearm.
• Avoid excessive force when connecting or separating joints.
• Clean with mild detergents; avoid abrasive tools that may scratch the glass.
• Suitable for autoclaving within the safe limits of Borosilicate Glass 3.3.
• Heat and cool gradually to avoid thermal shock.
• Ensure the vacuum line is properly supported to prevent strain on the sidearm.
• Do not expose the component to sudden mechanical stress or uneven heating.
