Rotary Evaporator condenser:How to choose the right type condenser ?

A rotary Evaporator can provide efficient evaporation of solvents; it is ideal for a single sample.

Key parts of a rotary evaporator system are water bath, glassware, vacuum pump, and circulating chiller. The evaporating flask rotates in the water bath, allowing for more surface area and easier evaporation. The condenser cools liquid moving through it, which allows the solvent to condense in the receiving flask. The vacuum pump lowers the boiling point of the solvent, allowing for faster evaporation.

Rotary Evaporator condensers are used in distillation and reflux processes and comprise of glassware. The apparatus assists in cooling liquids and condensing vapors or gasses from solutions. Their use allows hot solvent vapors from a heated liquid to cool and drip back, resulting in reduced solvent loss and lengthening the time to heat the solution. Standard tools do not involve electrical components.

The inner glass tubes contain ends equipped with graduated glass joints or grounded joints to fit other glassware. When reflux occurs, the upper end is kept open to the air or vented via a bubbler or drying tube, preventing water or oxygen from entering. The ground glass joints support connections with the apparatus. Select products rely on threaded fittings for water jackets connecting hoses for circulating the cooling fluid.

While, since condenser is so important to a rotary evaporator, do you know how to choose the right one?

How to choose the right type Rotary Evaporator condenser?

Diagonal condenser—Ideal for basic distillations of lower boiling point solvents and where height is limited.

Vertical condenser—Ideal for basic distillations of solvents with relatively low boiling points and where bench space is limited.

Vertical condenser with double jacket—Extra insulation from ambient temperature allows for higher recovery rates.

Vertical condenser for reflux—Separate centerpiece with a valve allows for more efficient condensation. Cold-trap condenser—Ideal for solvents with a high boiling point. Uses ice to cool the solvent more rapidly than the diagonal or vertical condenser.
