Round Top Column Adaptors

Round Top Column Adaptors

Round Top Column Adaptors are specialized glass components designed to provide smooth transitions and connections at the top of glass columns. Constructed from premium borosilicate glass 3.3, they offer excellent thermal resistance, chemical durability, and long-lasting performance for laboratory, pilot, and industrial-scale applications.

The round top design facilitates vapor and liquid flow, reducing turbulence and pressure drop while allowing easy integration with reflux dividers, condensers, and other auxiliary equipment. Custom dimensions are available for unique process requirements.

Key Features & Benefits

• Round top design ensures smooth flow and minimal turbulence
• Borosilicate Glass 3.3 construction for chemical and thermal resistance

How It Works (Step-by-Step)

1. Position the round top adaptor on the top of the column.
2. Connect auxiliary equipment such as feed pipes, reflux dividers, or condensers to the DN1 or DN2 ports.
3. Ensure proper alignment for smooth vapor and liquid distribution.
4. Secure ground glass joints using PTFE or metal clamps.
5. Monitor processes through transparent borosilicate glass.
