Allihn Condensers

Allihn Condensers

The Allihn condenser,also known as a “bulb condenser”,similar to a liebig condenser ,is designed with an inner tube consisting of a series of bulbs which increase the surface area availiable for vapor condensation surrounded by an outer jacket tube, the cool water flows through the outer jacket to condensate the vapor in the inner tube.Additionally,the Allihn condenser has a wider bore at the bottom and the condensed liquid can run down along the sides avoiding blocking the upward vapor.
Allihn condensers are used for laboratory-scale refluxing and provide a greater surface area than similar Liebig condensers.A reflux apparatus usually consists of an Allihn condenser used as a reflux condenser,a round bottom flask(single neck or multi-neck),a drying tube to prevent the atmospheric moisture from entering into the reaction,a separatory funnel or pressure equalizing funnel for adding reagents.Allihn condesner are also can be used in distillation apparatus and soxhlet extraction as an important part to connect the extract body with a larger scale.
It is designed with standard taper joint at top and bottom,and two glass hose connections or removable hose connections connecting the inner tube through which coolant flows,the lower hose used for coolant inlet,and the higher hose used for coolant outlet.
Made of high quality borosilicate glass 3.3 having very low?coefficients of thermal expansion for resistance to heat, and a very high resistance to chemical attack.Annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
