If you are a scientist who is interested in optimizing the use of your time, then you could benefit from suggestions on how to speed up evaporation in the lab.
It is possible to tweak your laboratory evaporation procedure so that the lab work is finished faster.
Start by choosing your glassware wisely.
Use larger flasks to increase the speed of your evaporation performance. Bigger flasks have a larger surface area which helps quicken the evaporation process. If you choose a beaker flask, consider that once your process is over, larger openings make it easier to collect your product and are much faster to clean up.
Monitor the height of the condensed solvent on the coils of the condenser and make sure to load no more than 75% of the condenser. You can achieve optimal condenser loading once the energy input for evaporation and the energy output through the condenser are in equilibrium. If your condenser is overloaded, consider increasing the pressure or lowering the cooling temperature. If the condenser is underloaded, consider decreasing the pressure or increasing the heating bath temperature.
