How much vacuum is needed for rotary evaporator?
When using a rotary evaporator, a vacuum is essential in order to reduce the pressure of the system, allowing the solvent to evaporate at a lower temperature. The optimal vacuum level needed for a rotary evaporator will depend on the solvent being used and the desired rate of evaporation. In order to achieve the best […]
What are the hazards of rotovap?
A rotovap, also known as a rotary evaporator, is a specialized type of laboratory equipment used to separate solvents from compounds. It is widely used in chemical and pharmaceutical labs, but can also be seen in other research laboratories, such as in food science and bioengineering. While rotovaps are incredibly useful pieces of equipment, they […]
The Basic Structure and Functions of Rotary Evaporator
Working Principle of a Rotary Evaporator A rotavap evaporates solvents from samples by utilizing the principle that the solvent will have a lower boiling point at a reduced pressure. Specifically speaking, the stepless speed regulation is adopted to make the evaporation flask rotate at a constant speed. By the rotation, materials can form a large […]

How Can We Use Rotary Evaporator for Extraction?
[ux_image id=”24452″ lightbox=”true” caption=”true” image_hover=”zoom” image_hover_alt=”zoom-fade” animate=”bounceInUp”] [gap] What is Rotary Evaporation? Rotary evaporation means that the evaporation is completed by rotary process. Under the 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 […]
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 […]
How to Use a Rotary Evaporator?
