Reflux Divider :
Manually Operated
Reflux dividers are used to take off the distillatefrom the column. Usually a valve is to be fitted ondistillate outlet which controls the reflux coarsely.

Note : DN2 is used for insertion of a thermometer pocket. A bellow is recommended on the distillate outlet DN1.
Reflux divider - Magnetically Operated :
These reflux divider are to be used with a electro-magnet and a timer. These have a swinging funnel mechanism which is operated magnetically from outside to remove the condensate or to return the reflux. Through this, correct control of reflux-ratio is possible. Funnel remains at 100% reflux position when magnet is inactive.
DN2 is used for insertion of a Thermometer Pocket. A liquid seal is recommended on the distillate outlet ofthis reflux divider to prevent the vapour passing directly to the receiver.
