Top head of column with high-efficiency condenser, without s ilvering

Function and Applications

This column head with integrated high-effenciency condensor serves for the adjustment of the reflux ratio of distillation columns, i.e. the separation of the arising condensate in reflux and drain, manual operated.

Benefits:

• It is suitably for operations under normal pressure.
• When the valve which is located in the drain tube is fully opened, the separator is adjusted for total distillation drain.
• The reflux ratio can be changed in finitely variable up to total reflux by turning the valve.
• For introduction of thermometers or temperature sensors with an outer diameter of 8 mm the column head has a connection with thread GL 18.
• The outflow for the distillate at the valve has a diameter of 12 mm.
• The column haed is delivered with an evacuated not coated insulating jacket.
• It has a non-jacketed basic ground jointcone NS 29.
• Through the renunciation of a silvering this apparatus is especially well suitable for training purposes.
• The full insight into the column haed during the process allows an especially ostentatious representation of the destillation separations.
• The high-effenciency condensor is connected with the column head firmly and has a non-jacketed head ground jointsocket NS 29 at the upper end.
• The condensor has 2 plastic hose couplings (Ø 8 mm) for the connection of the cooling water tubes.
