• Material: High-duty Borosilicate 3.3 Glass, providing excellent thermal shock resistance.
• Joints: Equipped with interchangeable ground glass conical joints (sockets) for vacuum-tight connections.
• Capacities: Commonly available from 100 ml up to 20,000 ml (20L).
• Typical Joint Sizes: Combinations such as 24/29 center with 19/26 side joints are standard.

• Angular Three Necks: The center neck is vertical, while the two side necks are 180° apart and inclined at a 20° angle. This is ideal for adding reagents via dropping funnels or inserting thermometers without interfering with a central condenser.
• Parallel Three Necks: The center neck and both side necks are vertical and parallel to each other. This setup is often preferred for mechanical stirring where multiple vertical shafts or probes are required.

1. Center Neck: Typically for a primary condenser or a mechanical stirrer.
2. Side Neck 1: Often used for an addition funnel to introduce reagents.
3. Side Neck 2: Used for monitoring (thermometer/thermocouple) or maintaining an inert atmosphere (gas inlet).
