      The rotary evaporator is an essential laboratory tool designed to enable efficient and precise separation and concentration of solvents from compounds. It is a highly complex piece of equipment comprising several critical components, including a vacuum pump, heating system, condenser, collection bottle, evaporation bottle, and adjustment knobs. This equipment is designed to facilitate the heating and evaporation of the sample solution, which is achieved through a circulation system that provides consistent temperature control. The sample solution is placed in a rotating flask, which is heated to initiate the evaporation of solvents. The rotation of the flask ensures that the sample is evenly heated, preventing overheating and providing a large surface area for effective evaporation. The vapor generated during the process condenses on the cooling surface of the condenser, allowing for the concentration or drying of the solution. The rotary evaporator's advanced design features and capabilities, including customizable parts, make it widely applicable across many industries, including pharmaceuticals, chemicals, biotechnology, and others. Overall, the rotary evaporator has revolutionized laboratory-based evaporation, providing highly efficient and precise separations while saving time and increasing productivity in a range of scientific applications.

  • Rotary evaporation equipment operation process:

    1. Loading the sample: add the mixture or reagent to be treated into the flask.

    2. Cooling system: the lower part of the condenser should be connected to a water tank in order to cool the condenser.

    3. Adjust the vacuum: Use the vacuum pump to pump out the gas inside the evaporation flask so that the liquid can evaporate more easily.

    4. Set parameters: Set the parameters of the rotary evaporator, such as rotational speed, heating temperature, etc.

    5. Observe the progress: by observing the change of solvent in the collection bottle and monitoring the status of the vacuum pump.

    6. Collect: When the evaporation reaches a certain level, collect it in a collection bottle for further processing or analysis.

  • Rotary evaporation equipment applications:

      The rotary evaporator serves as a crucial technology in the chemical industry, primarily for the concentration of liquid raw materials and products.
