Main functions and functions of glass reactor
The reaction medium can be stirred in the inner layer of the glass reactor, and the interlayer can be circulated through a cold heat source (refrigerant, water, heat transfer oil) to achieve constant temperature heating or cooling reaction, and the distillation and reflux of the reaction medium can be controlled. The glass reactor is an ideal test and production equipment for the preparation of modern synthetic chemicals, biopharmaceuticals and new materials.

Method and precautions during use of rotary evaporator
Rotary evaporators are primarily used to continuously distill large amounts of volatile solvents under reduced pressure. In particular, the concentration of the extract and the distillation of the receiving liquid in the chromatographic separation can separate and purify the reaction product.

How to choose a rotary evaporator when doing distillation purification experiments？
The rotary evaporator is an experimental equipment for rectification and purification in the laboratory. It is heated by constant temperature and rotated under reduced pressure (negative pressure) to form a film to continuously evaporate a large amount of volatile solvent, evaporate efficiently, and then condense and recover the solvent. The effect of purifying the separation, that is, under reduced pressure, the distillation flask is continuously rotated as the solvent is distilled.

Freeze-drying operation precautions for vacuum freeze dryer
Freeze drying of a vacuum freeze dryer refers to the process of removing moisture or other solvent from a frozen biological product by sublimation. Sublimation refers to the process of solvents, such as water, like dry ice, which does not pass through a liquid state and changes from a solid to a gaseous state.

What are the preparations for the freeze dryer before work？
It is well known that when using the freeze dryer for the first time, we must thoroughly clean all parts of the dryer. Everyone knows that stainless steel parts are cleaned with ethanol, and plexiglass is washed with normal saline. Ampoules are cleaned with an ultrasonic cleaner, but what preparations do we need to make before actually operating the freeze dryer?

Freeze dryer parts and usage analysis
The freeze dryer consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. It works by freezing the dried item below the triple point temperature and then sublimating the solid water (ice) in the item to water vapor under vacuum conditions, removing it from the item and drying the item.
