Magnetically Operated Reflux Divider

Magnetically Operated Reflux Divider

The Magnetically Operated Reflux Divider is a precision glass component designed for automatic control of reflux ratios in distillation columns. This type uses an external electromagnet and timer to swing the internal funnel, enabling accurate and repeatable reflux adjustment. When the magnet is inactive, the funnel remains at 100% reflux, ensuring continuous column operation.

Manufactured from borosilicate glass 3.3, these dividers provide excellent chemical and thermal resistance, suitable for laboratory, pilot, and industrial-scale operations. Liquid seals are used to prevent vapour bypass, maintaining process integrity.

Key Features & Benefits

• Automatic reflux control using external electromagnet
• Precise and repeatable operation
• Borosilicate Glass 3.3 for chemical and thermal resistance
• Thermometer pockets (DN2) for temperature monitoring
• Liquid seals to prevent vapour leakage
• Reduces manual intervention, increasing process efficiency
• Flexible DN connections for easy integration

How It Works

1. Install the reflux divider at the top of the distillation column.
2. Connect the external electromagnet and timer to control the swinging funnel mechanism.
3. The funnel automatically adjusts the reflux ratio based on magnet activation and timer settings.
4. Insert a thermometer into the DN2 pocket for temperature monitoring.
5. Use liquid seals to prevent vapour bypass, ensuring accurate distillate collection.
6. Monitor operation visually through the transparent glass body.
