A reflux apparatus allows for facile heating of a solution, but without the loss of solvent that would result from heating in an open vessel in a reflux setup, solvent vapors are trapped by the condenser, and the concentration of reactants remains constant throughout the process. Reflux apparatus. The picture below shows a reflux setup for a macro-scale experiment used in upper division laboratories eg chem 144 and chem 174 it consists of a round bottom flask, a reflux condenser (water-jacketed) and heating source (here: heating mantle) the entire setup is connected to an inert gas line since the used starting material or products.
reflux apparatus
Reflux is a distillation technique involving the condensation of the distilled product vapors and the return of a portion of the condensate to the distillation system from which it originated reflux is widely used in large-scale, industrial continuous distillation columns as well as in laboratory distillation apparatus setups. How to set up a reflux apparatus introduction reflux is a chemistry lab technique that heats a solution, produces vapor, and then condenses and returns the outgoing vapor into its original mixtures. reflux is widely used in undergraduate organic chemistry labs. before doing this activity, students should have experience using boiling chips,. Setting up the apparatus for reflux with mechanical stirring is a precision task and is described in box 16.2. the major problems encountered are: the weight of the stirrer motor high up on the support stand: use a large support stand with a heavy base or use a support framework, which is screwed to the laboratory bench. besides the motor's.
