How to make Rotary Evaporation Process faster
There are three main factors that can influence the speed of general evaporation, which are temperature, evaporation area and air velocity. Therefore, when we want to speed up evaporation, we need to change one or more of these factors. What’s more, solar radiation, temperature, humidity, water vapor pressure difference, wind speed, water surface area, water depth, and water quality can also influence the speed of evaporation.
How do you process rotary evaporation
Users can speed up rotary evaporation process through controlling the temperature, evaporation area and air velocity. For example:
1.Increasing temperature can speed up rotary evaporation process
As the temperature of the water increases, the speed of movement of the water molecules will accelerate, making it easier to escape from the water surface, so the evaporation of the water surface will increase as the temperature of the water surface increases.
2.Increasing evaporation area can speed up rotary evaporation process
The evaporation surface of the water body is a passage that water molecules must evaporate. Generally speaking, the larger the water surface area, the greater the amount of evaporation and the faster the evaporation. For a local area, the larger the water surface area, the less easily the water vapor above it is taken away from the water surface area.
3.Increasing air velocity can speed up rotary evaporation process
Within a certain range, the greater the wind speed and the faster the air flow is, the more conducive to the convection and exchange of water vapor in the air, thereby increasing the water vapor pressure difference at the water vapor interface, and the more favorable to the evaporation of the water surface.
Factors to make Rotary Evaporation Process faster
Rotary evaporation is one kind of evaporation, which has the characteristic of rotating. Rotary evaporation is more high-efficiency than other evaporation methods, because rotating makes a larger evaporation area, which can speed up evaporation.
So how can we do rotary evaporation very well?
When users are operating a rotary evaporator, there are several parts working together in the whole system to achieve the evaporation. The solvent in the evaporation flask gets heated by a heating bath, and the heating temperature are supposed to set as the boiling point of the solvent. At the same time, it can also be rotated to make the solvent form a thin film to increase the evaporation area.
In addition, under the action of a high-efficiency cooler, the hot steam can be quickly liquefied to speed up the evaporation rate.
