About Rotary Evaporators
A rotary evaporator is a laboratory instrument commonly used in the chemical and pharmaceutical industries to to remove solvents following chemical reactions ,efficiently separate and purify liquids through evaporation. The process involves rotating a flask containing the liquid to be evaporated while it is gentle heated in a water bath. As the liquid inside the flask rotates, it forms a thin film on the walls of the flask, allowing for a larger surface area for evaporation.
One key component of a rotary evaporator is the vacuum pump. The purpose of the
Vacuum Pump is to remove air from the system, creating a reduced pressure environment that allows the liquid to to accelerate distillation and evaporate more quickly. This is because the lower the pressure, the lower the boiling point of a liquid. By reducing the pressure, the liquid can be heated to a lower temperature while still achieving the same level of evaporation.
Rotary evaporators need dry vacuum pump,solvents resistant PTFE rugged construction to resist harsh solvent vapors
With traps to protect the pump from liquids
Vacuum distillation is a process used to separate and purify liquids by evaporating them and condensation under vacuum. This process is commonly used in the chemical and pharmaceutical industries to separate and purify a wide range of liquids, including organic compounds, essential oils, and other volatile substances.
The basic principle of vacuum distillation is that the boiling point of a liquid decreases as the pressure decreases. By reducing the pressure in the distillation system, the liquid can be heated to a lower temperature while still achieving the same level of evaporation. This allows for the separation and purification of the liquid into its various components.
To perform vacuum distillation, a vacuum pump is used to lower the boiling point of the liquid. The liquid to be distilled is placed in a distillation flask, by heating the liquid until boiling occurs, which is then connected to a condenser to cool and collect the vapor as it evaporates. The vapor is then condensed back into a liquid and collected for further purification or analysis.
Vacuum distillation can be used to separate and purify a wide range of liquids, including those that are sensitive to heat or have a high boiling point. It is a useful tool in the chemical and pharmaceutical industries, as it allows for the efficient separation and purification of liquids with a high level of purity.
Vacuum Distillation applications need chemical dry diaphragm pumps or rotary vane vacuum pumps.
