Jul 10, 2021· A rotary evaporator is used to remove the unnecessary solvents and eliminate solvent bumping. The centrifuge works by lowering the pressure of the chaer, which also decreases the boiling point of the samples. This causes the solvents to be evaporated, concentrating the particles to be separated. Types of centrifugation. 1. Analytical
The fins are added to the bare-tube to increase the heat transfer capability. They act as heat collector that pick up heat from the surrounding air and conduct it to the refrigerant inside the tube hence improving the efficiency in cooling the air of the surrounding. They are best used in the air-cooling space where the temperature is around 34°F.
