Rotary evaporators come in a range of capacities, from 2 liters to 50 liters.
These devices are mainly used for removing solvents in chemical reactions.
They are available in various sizes to suit different project needs.
2L Rotary Evaporator: Compact and Efficient
This model is equipped with a 2-liter flask and an additional 1-liter flask for collecting the finished product.
It operates at rotating speeds from 0 to 120 R/min and evaporation speeds from 1.5 to H20.
The temperature range for operation is from RT-99 degree Celsius to -299 degree Celsius, ensuring efficient performance under various conditions.
Larger Rotary Evaporators: Versatile and Powerful
Rotary evaporators are also available in sizes like 5L, 10L, 20L, and 50L, suitable for different stages of laboratory tests, pilot tests, and production.
For example, 2L, 3L, and 5L models are ideal for small volume laboratory tests, while 20L and 50L models are suitable for both pilot tests and production.
In special cases, continuous feed tubes can be used to expand the volume of the evaporation bottle, allowing for continuous distillation of larger amounts.
Applications and Additional Components: Essential for Operation
Rotary evaporation is particularly useful for concentrating heat-sensitive analytes, as it allows for the reduction of atmospheric pressure and increases the surface area of the solvent, making heat application optional.
Recommended sample sizes for rotary evaporators range from 25 mL to 2 L, with average evaporation times of around 5 to 20 minutes.
Additional components such as chillers and vacuum pumps are required for operation.
Specifications and Pump Requirements: Matching Capacity with Performance
Benchtop rotary evaporators with volumes up to 5 liters typically require chemistry diaphragm pumps with pumping speeds of approximately 1-2 m3/h.
Large-scale rotary evaporators with volumes up to 20 liters require pumps with higher pumping speeds, around 3-5 m3/h.
In summary, the capacity of rotary evaporators varies significantly to cater to different scales of operations, from small laboratory tests to large-scale production, with capacities ranging from 2 liters to 50 liters.
