With nearly 20 years of experience in glass reactor design and manufacturing, Perfectlight technology can provide glass reactors for different reaction types, reaction systems, sizes and application scenarios. 

How to choose a glass reactor 

1. Make clear the application reaction type of glass reactor

When selecting glass reactor, specific reaction type and reaction conditions should be clarified first.

• In photochemical reaction, in order to match the irradiation of xenon lamp source, LED light source and other light sources, the glass reactor is mostly the top illumination type (offline reactor and online reactor).

• In electrochemical and photoelectrochemical experiments, different types of working electrode, reference electrode and counter electrode need to be fixed. The fixed position of electrode and the overall air tightness of the reactor need to be considered comprehensively. The glass reactor is side-illumination type (offline and online photoelectric reactor).

• In the photosynthesis and photoexcitation reaction, the mercury lamp tube is used as the deep ULTRAVIOLET light source when 200-350 nm deep ULTRAVIOLET light source is needed, and the quartz cold trap and internal illumination reactor can be used for the experiment. 

• In the gas-solid reaction such as CO2 reduction, it is necessary to consider the placement of catalyst and ensure sufficient contact between catalyst and the reaction atmosphere. Gas-solid reactor can be used.

2. Define the specifications and dimensions of the glass reactor 

After the application scenario of the glass reactor is determined, you need to specify the specifications of the glass reactor, that is, the volume of the glass reactor. The volume can be divided into total volume and effective volume. 

Total volume refers to the total volume of cavities in the glass reactor. 

The effective volume is the actual volume of the reaction material contained in the glass reactor.

3. Define the overall scene of the experiment 

• The glass reactor is only a part of the overall scenario of experimental applications, as well as other equipment closely associated with the experiment such as different types of gases, cryogenic thermostatic tanks, atmosphere mixing devices and vacuum pumps. 

• If the glass reactor needs to be connected with other equipment, the specific connection method and the specific joint size must be specified. 

• If the reaction in the glass reactor is in the process of feeding/sampling, it is necessary to clarify the feeding/sampling phase state and specific feeding/sampling method, and then clear the feeding/sampling form and specification of the glass reactor;

• If the reaction in the glass reactor is to be carried out in a vacuum, the glass reactor must have a high air tightness and a valve connected to a vacuum pump for vacuumization. 

• If the reaction in the glass reactor needs to be carried out at a certain temperature, the glass reactor can use an integrated water jacket, and it should be noted that the reaction at a higher temperature is not carried out in the glass reactor as far as possible.

• If the glass reactor needs to be connected to the gas pipeline, the interface of the glass reactor can be made into a valveable port for connecting the gas and metal pipeline.
