Manually Operated Reflux Divider

Manually Operated Reflux Divider

Manually Operated Reflux Dividers are precision glass components used to control the reflux ratio in distillation columns manually. These dividers allow coarse adjustment of distillate flow using a valve on the distillate outlet (DN1). Constructed from borosilicate glass 3.3, they offer excellent thermal and chemical resistance for laboratory, pilot, and industrial-scale operations.

This type of divider is simple, reliable, and maintenance-friendly, suitable for processes where automated control is not required, but accurate reflux management is necessary. Thermometer pockets (DN2) can be integrated for temperature monitoring, and liquid seals prevent vapour bypass, ensuring process integrity.

Key Features & Benefits

• Manual control for adjusting reflux ratio
• Borosilicate Glass 3.3 for thermal and chemical resistance
• Thermometer pockets for accurate temperature measurement
• Liquid seals prevent vapour leakage
• Simple, reliable, and low-maintenance design
• Flexible DN connections for integration with distillation columns

How It Works

1. Install the divider at the top of the distillation column.
2. Adjust the manual valve on the distillate outlet (DN1) to control the reflux ratio.
3. Insert a thermometer into the DN2 pocket for temperature monitoring.
4. Optionally, use liquid seals to prevent vapour bypass.
5. Monitor the distillate flow visually through the transparent glass body.
