Air Leak Tube / Gas Inlet Tube is an essential laboratory glassware accessory used to regulate airflow or introduce gases into closed reaction, distillation, or reflux systems. It allows controlled admission of air or inert gas, helping to balance pressure and ensure smooth operation under reduced or atmospheric pressure conditions.

Manufactured from high-quality, chemically resistant glass, this tube offers excellent transparency, durability, and compatibility with common laboratory chemicals. The precision-ground cone joint ensures a secure, leak-free connection with standard laboratory glassware.

Air leak tubes are frequently used in distillation setups to prevent vacuum lock, facilitate smooth boiling, or allow gentle introduction of inert gas during sensitive reactions. Their simple design makes them reliable and easy to integrate into modular glassware assemblies.

These tubes are suitable for:

• Controlled air or gas inlet
• Pressure equalization in closed systems
• Distillation and reflux assemblies
• Inert gas purging and flow control
• Academic, research, and industrial laboratories

Available with standard ground glass cone sizes including 14/23, 19/26, 24/29, and 34/35, air leak tubes integrate seamlessly into modular laboratory glassware systems.

Air leak tubes and gas inlet tubes combine simple construction, reliable joint compatibility, and effective pressure control, making them indispensable accessories for laboratory gas handling applications.
