The uses and applications of rotary evaporator, and the using steps of rotary evaporator.

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 […]

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 Can We Use Rotary Evaporator for Extraction?

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 flask so as to increase the evaporation area. […]

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 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?

A rotary evaporator (rotovap or rotavap) refers to a kind of equipment for solvent evaporation under reduced pressure, which is composed of a vacuum system, a heated water or oil bath, a condenser and a motor that rotates the evaporation flask. They cooperate with each other and all play an essential role in the working process […]

How does a Freeze Dryer Work?

A freeze dryer is one of the most common and essential drying equipment, which is used to dry items by utilizing the freeze drying technology. It usually consists of four components, including a drying chamber, a vacuum pump, a heat source and a condenser. How does a Freeze Dryer work? The working process of a […]
