Instructions
1. Preparation: Connect the power supply. Before using the instrument, first put the eight-position reactor (or magnetic stirrer) into the main box, and put the magneton into the quartz reaction tube (or reaction container). After that, check whether the mercury lamp (xenon lamp), reactor and cooling water circulation device to be used are connected properly. (Connect as shown below)
2. There is an eight-position reactor (or magnetic stirrer) and lamp power supply interface in the reaction dark box. Please connect according to the instructions.
3. Adjust the light source selection on the controller, so that the light source used is consistent with the one on the controller (different according to the type of light source and power)
4. Turn on the fan switch, the reactor and the light switch on the controller in sequence, and the fan starts to work (the air in the reaction dark box starts to drain out.
5. Turn on the power switch on the eight-position reactor (or magnetic stirrer) and adjust the stirring speed as required.
6. The light source power adjustment is located in the center of the controller, and the light source power can be adjusted as needed.
7. There is a microcomputer timer on the upper right of the controller, and the working time can be set as needed.
Note: When using mercury or xenon lamps for experiments, the lamp source must be placed in a quartz cold trap (it is recommended to use a low-temperature cooling circulation device at the same time to avoid instrument damage due to excessive temperature).
Reaction black box
The main box is the place where the illumination device of the series photochemical reaction instrument is placed, and has the following characteristics:
The inside of the cabinet is black to reduce light reflection.
There are 2 cooling water inlets and outlets at the rear of the cabinet.
The photoelectric parameters of the high-pressure mercury lamp of the photochemical reaction instrument are as follows:

The light emitting part of the mercury lamp of the photochemical reaction instrument is a quartz tube. Direct hand contact will cause pollution and affect the light intensity. The outside of the quartz vessel is usually cleaned with a small amount of alcohol and wiped with a small amount of alcohol, and the inside is washed with lotion.
The controller panel is equipped with switches for total power, light selection, light power, and light start. There is a fan in the controller to remove heat. There is a fuse holder on the back of the chassis. The back of the controller is provided with a 220V power input line interface.

Photochemical reaction instrument full quartz glass light source protection cold trap
The all-quartz or improved glass material light source protection cold trap not only has high-efficiency penetration rate of ultraviolet light, but also takes away the temperature problems caused by the light source working for a long time, ensuring that the reaction substance only receives light and does not contain effects other than the experiment itself .
