The 50L-100L rotary evaporators, as large ones independently researched and developed by our company, are currently for sale.
Generally, the main body of a rotary evaporator is equipped with universal wheels that makes the whole machine move easily. The bath kettle is capable of being lifted and lowered automatically or manually. The brushless motor is adopted, which is safe, stable and without noise. The rotating speed can be displayed by LCD digitally. The main and auxiliary condensers are equipped, with a better condensation effect and higher recovery rate. It’s especially suitable for concentration, crystallization, separation and solvent recovery of the thermal sensitive material, corrosive material and metal material like the stainless steel, as it works under the vacuum condition and its parts exposed to materials all use the high borosilicate glass and PTFE material that are heat resistant.
What are purposes of a rotary evaporator?
As a common and essential equipment used in laboratories and industries, a rotary evaporator has a great number of purposes. It is mainly used for the process of evaporation, concentration, crystallization, drying, separation, and solvent recovery, and especially used for the continuous distillation of large amounts of volatile solvents under reduced pressure. With so many application purposes, there is no doubt that a rotary evaporator can be applied in many areas. For example, it can be used in the small and pilot experiments and production in the biological, pharmaceutical, chemical fields and even food-making industries.
How does a rotary evaporator remove solvent?
The basic working principle of a rotary evaporator removing solvent is that the sample materials are evaporated through the evaporation flask’s continuous rotation. There are several necessary components involved in the process of removing solvent, including a evaporation flask, a water/oil bath, a vacuum pump, a condenser and a receiving flask. Specifically speaking, the stepless speed regulation is adopted to make the evaporation flask rotate at a constant speed. By the rotation, materials can form a large area of uniform thin film on the inner wall of the flask. The evaporation flask is heated evenly by a water or oil bath, and materials, with a lower boiling point, is evaporated rapidly under the vacuum condition. The solvent steam is recycled in the receiving flask after being cooled by the high efficiency glass condenser. The process of removing solvent is completed.
