Cone with Stem � Rubber Tubing Right-Angle Adapter is a laboratory glassware accessory used to interface ground glass joints with flexible rubber tubing in gas, vacuum, or liquid transfer applications. The right-angle stem design enables directional hose routing, reducing strain on connections and improving space management within laboratory setups.

Manufactured from high-quality, chemically resistant glass, this adapter offers excellent transparency, durability, and compatibility with common laboratory chemicals. The precision-ground cone joint ensures a tight, leak-free fit with standard glassware, while the stem provides a secure grip for rubber tubing.

The right-angle configuration is particularly useful where straight connections are impractical, helping to prevent kinking of tubing and maintaining smooth flow.

This adapter is suitable for:

• Vacuum and inert gas line connections
• Gas inlet and outlet routing
• Flexible hose connections in compact assemblies
• Schlenk line and general laboratory applications
• Academic, research, and industrial laboratories

Available with standard ground glass cone sizes including 14/23 and 19/26, these adapters integrate seamlessly into modular laboratory glassware systems.

Cone with stem right-angle adapters combine secure joint compatibility, flexible hose connection, and space-saving design, making them reliable components for laboratory fluid and gas handling.
