Liquid Dividing Fractional Distillation Head

A sluice type reflux ratio head combined with a jacketed coil condenser having an approximate surface area of 4.0 x 10–2m2. A run-off lip at the bottom of the condenser directs condensed vapour to a weir from which it is either returned to the column or collected. The proportion of liquid returning to the column is adjusted using a GP Rotaflo stopcock. The head is fitted with a pressure equalising tube with vacuum connection, making it an ideal unit for reduced pressure distillations. A size 13 screw-cap is also provided for the insertion of a thermometer (not included). Supplied with screwthread outlets and plastic screwthread connectors
