[0029] The cover 20 is fixed to the base 10 to form an operating cavity, which is used for experiments. Multiple sets of casters 11 are installed at the bottom of the base 10. These casters 11 are self-locking casters selected from the market. The position of the test bench can be adjusted by moving the casters 11, and they can be locked after movement to maintain stability.

[0030] The cover 20 is made of opaque material. A transparent door panel 21 is pivotally connected to the front of the cover 20. The door panel 21 can block the operating cavity. The door panel 21 can be opened and closed by pivoting the door panel 21. Experimental tools or experimental materials can be put into and taken out of the operating cavity. After the experimental tools or experimental materials are put into place, the door panel 21 is used to block the operating cavity to form an experimental environment isolated from the outside.

[0031] The enclosure 20 is equipped with an illumination component 30, and the door panel 21 is covered with a filter layer 211. The filter layer 211 filters the light to prevent light of specific wavelengths from entering the operating cavity and reduces the light intensity entering the operating cavity. When conducting experiments in the operating cavity, the influence of strong external light on the experiment is effectively reduced. The illumination component 30 includes multiple monochromatic light sources 31 set on the inner top wall of the enclosure 20 and a panel 32 set on the outer wall of the enclosure 20. The panel 32 is used to control the multiple monochromatic light sources 31. The illumination component 30 provides low-intensity light to the operating cavity without affecting the experiment.

[0032] An operating part is provided on the door panel 21. The operating part includes holes 22 opened on the door panel 21. There can be one or more sets of holes 22, and each set of holes 22 is connected to a rubber glove 221 that can extend into the operating cavity, so that the staff can put their hands into the rubber glove 221 to perform experimental operations.

[0035] A rod 201 is movably inserted into the cover 20, and a sleeve 212 is provided on the outer wall of the door panel 21. The rod 201 can be inserted into the sleeve 212. When the door panel 21 pivots to block the operating cavity, inserting the rod 201 into the sleeve 212 will limit the door panel 21 and prevent the door panel 21 from being accidentally opened during the experiment.

[0036] A filter 421 is provided at the inlet end of the air intake pipe 42. The filter 421 can be detachably connected to the air intake pipe 42 by bolts or the like. The inlet end of the air intake pipe 42 is set downwards, and the air pipe is a bend, so that external light is not easily allowed to enter the operating chamber through the air intake pipe 42. The filter 421 filters the incoming air to remove dust and impurities.

[0037] Example 3 provides a light-shielding test bench.

[0038] The drain pipe 412 is connected to a filter cartridge 413, which is equipped with an adsorption material. The adsorption material is preferably activated carbon, adsorption resin or other materials that can adsorb organic reagents, so as to avoid the extracted organic reagents being directly discharged into the outside air and causing pollution.

[0039] An electric cylinder 24 is installed on the inner bottom wall of the cover 20. The movable rod of the electric cylinder 24 is connected to the support platform 23. The support platform 23 has multiple placement slots 231. The height of the support platform 23 can be adjusted by controlling the extension and retraction of the electric cylinder 24.
