The utility model discloses a constant temperature experiment box for NVP
monomer storage in the technical field of constant temperature experiment boxes, which comprises a box body and a box door, a hinge is arranged at the joint of the box body and the box door, and an observation window is arranged on the box door. A mesh plate is arranged in the box body, a plurality of
test tube placing holes are formed in the mesh plate, a heat preservation
sponge is arranged below the mesh plate, a plurality of
test tube placing grooves in one-to-one correspondence with the
test tube placing holes are formed in the heat preservation
sponge, and test tubes are inserted into the test tube placing holes and the test tube placing grooves which correspond up and down. A first vertical groove is formed in the right side of the heat-preservation
sponge, a second vertical groove is formed in the left side of the heat-preservation sponge, and a plurality of horizontal air channels communicate between the first vertical groove and the second vertical groove. A fan heater is arranged on the right side of the box body, an air outlet
pipe of the fan heater communicates with the first vertical groove, and an air outlet in the
tail end of the air outlet
pipe faces the horizontal
air channel. The reaction kettle is simple in structure, good in heat preservation performance and good in damping performance, and
reagent leakage risks are reduced.
