Rotary evaporator to understand the application field and common sense of the rotary evaporator

Rotary evaporator ? -------- Understand the application field and common sense of the rotary evaporator

 

    Rotovap is widely used as a laboratory instrument evaporator for reflux operation, rapid evaporation, concentrated to a minor component and the like during the reaction requires stirring large amounts of solvents. The system may be sealed to a reduced pressure of 400 to 600 mm Hg; distillation flask was heated with a heating bath of the solvent, the heating temperature is the boiling point of the solvent accessible; while also rotating speed of 50 to 160 rev / min, the solvent is formed The film increases the evaporation area. In addition, under the action of a high-efficiency cooler, the hot vapor can be quickly liquefied to accelerate the evaporation rate.

 

Rotary evaporator is an indispensable instrument for evaporation, concentration, crystallization, drying, separation and solvent recovery in scientific research and production processes in the pharmaceutical, chemical and biological products industries. It is developed by applying vacuum vacuum condition, constant temperature heating and thin film evaporation.

Rotary evaporators are used in teaching experiments in the laboratory. It consists of an electric heating device, an evaporation bottle, and a collection bottle, and a bump is provided on the outer surface of the evaporation bottle. The utility model has the beneficial effects that: during the experiment, when the evaporation bottle is placed on the table top, it is not easy to roll, and is not easy to break, thereby reducing the experimental expenses of the school.

   

    Our production and sales of a rotary evaporator using a rotary evaporator flask (flask), increasing the evaporation area. Water bath was placed under reduced pressure, the solution was evaporated diffusion efficient, widely used in chemical, pharmaceutical, food, environmental and universities Scientific research and small batch production and Other units , ideal equipment for concentration , drying and recycling .

 

    The rotary evaporator of the company produces and sells Teflon water bath, full transparent protective cover, heat preservation, energy saving, explosion-proof, splash-proof, rust-proof and anti-pollution.
