What is the Purpose of Water Bath in a Rotary Evaporator

A rotary evaporator, also known as rotovap or rotavap, refers to a type of equipment for solvent evaporation under reduced pressure. It is generally composed of a vacuum system, a condenser, a motor and a heated water or oil bath. The vacuum system can be used to reduce the pressure within the rotary evaporation system […]

How We can Use Rotary Evaporator for Extraction?

What is Rotary Evaporation? Rotary evaporation means that the evaporation is completed by rotary process. Under low temperature and negative pressure, the evaporation flask is rotated by a motor in a thermostat water bath, which makes liquid form a thin film across the interior of the flask so as to increase the evaporation area. It […]

What is a Stainless Steel Reactor?

The lab reactor refers to the vessels for physical or chemical reactions that is primarily composed of four components, including the inner tank, jacket, stirring device, and supporting seat. There are two main types of lab reactors in terms of their various materials, which are glass reactors and stainless steel reactors respectively. The stainless steel […]

What is the Primary Advantage of a Rotary Evaporator over Distillation?

Rotary evaporators are common laboratory equipment mainly composed of a motor, a rotating flask, a water or oil bath and a condenser tube and other components. It is an essential equipment for concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and bio-pharmaceutical fields and other fields. As for the distillation, it refers to […]

What is Crystallization?

The crystallization is an important technology for separating or purifying some materials, which can be widely used in a great variety of fields, such as chemical engineering, food engineering, and bioengineering. What is Crystallization? The crystallization is a process in which solid substances in crystalline state precipitates from steam, liquid or molten material. The crystallization […]

What are Applications of a Rotary Evaporator?

What is a Rotary Evaporator? A rotary evaporator is an indispensable equipment for the processes of evaporation, concentration, crystallization, drying, separation, and solvent recovery in many fields, and it is mainly used for continuous distillation of large amounts of volatile solvents under reduced pressure. It can be said that a rotary evaporator has a great […]

The Role that a Cold Trap Plays in a Rotary Evaporator

Generally, a rotary evaporator is primarily composed of four components, including a water bath for heating, a motor for rotating the evaporation flask, a condenser for condensing the evaporated sample as well as a cold trap. Many people may wonder the role that a cold trap plays in a rotary evaporator. Well, it will be […]
