A containment box is a common laboratory procedure used to isolate samples or reagents from the outside environment during certain experiments or operations to prevent cross-contamination or protect the safety of the operator. The following is the general isolation closed box operation method:
< br >
1. Preparation:
Ensure that the work area is clean and tidy, and disinfect the work surface.
Check the operating status of the isolation enclosure to ensure its normal operation.
Prepare the required experimental materials and reagents.
2. Wear personal protective equipment:
Wear personal protective equipment such as lab gloves, lab coats, and goggles.
3, put the sample or reagent into the isolation sealed box:
Open the door of the isolation enclosure and place the sample or reagent to be handled into the enclosure.
Be careful not to extend hands or other objects into the box during operation to maintain a closed state.
4. Experiment or operation:
Perform the required experiments or procedures in an isolated enclosure.
Take care to follow laboratory procedures to avoid spatter, spray, or other conditions that may cause contamination or danger.
5, Complete the experiment or operation:
After the experiment or operation is completed, put the waste or pollutants generated into the designated container to avoid direct contact with the external environment.
Close the door of the isolation enclosure to ensure airtight condition.
6. Cleaning and disinfection:
After the end of the experiment, the isolation box should be cleaned and disinfected to prevent cross-contamination.
Clean work surfaces and other used laboratory equipment.
Please note that the specific operation method of the isolation enclosure may vary according to different equipment models and experimental requirements. Before performing any experiment or operation, please read and follow the operating manual of the equipment and experiment carefully, and follow the relevant safety regulations and laboratory operating procedures.

1, first play a mounting hole in the furniture countertop, fix the junction box with screws, and carefully check the elevation.
2, connect the cable in the junction box, if it is a pop-up box, the cable should be left longer, so that the junction box can spring up smoothly.
？
3, it should be noted that the junction box should be grounded with the pipeline, if it is a buried junction box, it should be grounded with the welded steel pipe.
4, finally, lay out the cable, and reserve the equipment hole, the reserved electric gas well, hole, hole position size should be appropriate.
