Water bath evaporator is a kind of instrument and equipment widely used in the fields of chemistry, pharmacy, food and environment. It mainly uses the heat of water vapor to dissolve the solute in the liquid, and then evaporates the water from the liquid to obtain Purified solute. There are many types of water bath evaporators on the market, the common ones include rotary evaporators, horizontal evaporators, vertical evaporators, etc.
The rotary evaporator is one of the most widely used evaporators. It uses a sturdy and durable motor with a large rotating area. It places the liquid in a rotating bottle and uses the inertia of high-speed rotation to disperse the solvent over a large area of glass surface. The water is evaporated and the solute is concentrated inside the rotating flask. This evaporator has the advantages of low power consumption, good stability, and easy operation. It can ensure that the solute is not subject to thermal decomposition and has extremely high purity.
The horizontal evaporator places the liquid in a water bath heater and uses external heat to heat the liquid to concentrate the solute. During the solution concentration process, the water continues to evaporate, thereby achieving the purpose of purifying the liquid. This kind of evaporator mainly relies on the water bath to have high temperature stability and is not prone to severe temperature fluctuations. It is easy to use, has a simple mechanical structure and works stably, so it has been widely used in actual operations.
Vertical evaporators are mainly used in large-scale production processes. Its structure is larger and can process more substances at one time, improving production efficiency and reducing operating costs. Its operating principle is similar to that of a horizontal evaporator. It also uses external heat to heat and evaporate liquid, or uses some different power sources to ensure its normal operation.
