2022-3-17 · Generally, the larger the evaporating flask, the greater the evaporation rate. This is because a larger flask allows for an increased velocity at the perimeter of the flask. With higher speed, the solvent inside the flask becomes more agitated and the active surface area of the solvent is enlarged. This all results in a higher evaporation output.

What is the advantage of using a rotary evaporator

2021-5-11 · What is the advantage of using a rotary evaporator? Since low pressure is used, a rotary evaporator is also quite efficient at removing the last traces of residual solvent from a solution. Figure 5.66: a) Solution is placed on a rotary evaporator, b) After evaporation (solvent is in the receiving flask).Aug 3, 2021.

Rotary evaporator working principle

Rotary evaporator is a rapid concentration device. Our best-selling rotary evaporators include 5L rotary evaporator, 10L rotary evaporator, 20L rotary evaporator and so on. The principle of the rotary evaporator is that the sample is heated and decompressed in a spherical glass container, and continuously rotated to increase the evaporation surface area and accelerate the …
