Rotary Evaporator Cooling

 

Rotary Evaporator Cooling

 

Choosing the right cooling method suitable for the evaporation process has a greater impact on the performance, economy and handling of the entire system than you initially believe. When purchasing a new rotary evaporator system or process changeover, the choice of the cooling system is one of the key decisions that not only determines the subsequent throughput but also the work processes in the laboratory. Economic factors such as payback period and running costs, as well as sustainability should also be considered and taken into account when deciding for or against a variant for cooling.

 

Rotary Evaporator Cooling Technology And Solutions

Rotary evaporator is a commonly used equipment in the laboratory, mainly used for continuous distillation of a large amount of volatile solvents under reduced pressure. Especially for the concentration of the extract or the distillation of the receiving liquid during chromatographic separation, the reaction product can be separated and purified. The basic principle of the rotary evaporator is distillation under reduced pressure, that is, under reduced pressure, the distillation flask rotates continuously to evaporate the solvent.

Condensation is an essential step when using a rotary evaporator for operation. In the experiment, the faucet is usually directly connected to the condenser through a water pipe, and water is passed through the faucet for condensation, and the condensed water is passed directly to the condenser. To the pool, discharged into the sewer, this condensation method can only be used for one-time use of water, which is a waste of water resources. Therefore, we have designed a rotary evaporator with a circulating water refrigeration device, which can allow the condensed water discharged after absorbing heat to return to the condenser for condensation after the cooling effect of the circulating water refrigeration device cools down, so as to realize water recycling, saving water resources, and the cooling speed is fast, and the cooling effect is good.

Choosing the right cooling method for an evaporation experiment can have an unimaginable impact on overall system performance, economy, and efficiency. As a necessary stage of the distillation process, the commonly used condensation methods currently include: using dry ice condensers, equipping or building a cooling system, and using tap water for steam cooling. But in most cases, it is necessary to purchase a refrigerated circulator as supporting equipment.

When the refrigerated circulator is running, it cools the coolant filled in the water tank through its refrigeration system, and the built-in pump pumps the coolant into the condenser pipe to absorb the heat of the steam in the condenser to achieve the effect of condensation. The coolant with elevated temperature flows back to the water tank to cool down again. In this way, the cooling is circulated and exchanged to provide a stable condensation temperature for the rotary evaporation system, while effectively avoiding seasonal temperature fluctuations that may occur when tap water is used. Moreover, choosing an efficient and environmentally friendly chiller to replace tap water for cooling will also help the laboratory save water.

Important factors to consider when choosing the recirculating chiller:

  • Minimum condensation temperature and corresponding cooling capacity
  • Cycle pressure
  • Circulation flow
  • Suitable accessories
