The invention provides a drawer, which comprises a drawing body. The drawing body and the inner wall of a refrigerator are matched through idler wheels and sliding rails, an inclined plate is arrangedon the side, facing a user, of the drawing body, the inclined plate and the drawing body are fixed together, and the inclined plate is downwards obliquely arranged from inside to outside. The drawerhas the beneficial effects that through arrangement of the inclined plate, an operator can conveniently take, observe and store reagent solutions stored in the explosion-proof refrigerator, the drawing body of the drawer and the refrigerator adopt a sliding wheel and sliding rail structure, and thus the hidden danger that the solutions in the explosion-proof refrigerator collide and then explode is reduced.
