DURAN® spherical condenser (Allihn condenser), NS 24/29, 250 mm The spherical condenser is similar in design to the Liebig condenser. Its internal riser tube is constricted at equal intervals. This creates the typical spherical shape that gives it its name. Due to this shape, the cooling surface is enlarged compared to the Liebig cooler and creates a stronger steam turbulence. Special features and advantages: Compared to the Liebig condenser, the bulb condenser has a larger cooling surface and thus a higher cooling capacity Two unscrewable plastic olives for inflow and outflow of the cooling medium Tight closure due to standard ground joint Application: reflux condenser for condensation and return of the (solvent) vapours to the reaction mixture, distillation, product and reflux condenser, condenser of length 250 mm (with NS 24/29 and NS 29/32) and 400 mm (with NS 24/29) are special sizes and not according to DIN.
