Experimental box for agar diffusion experiment

Abstract

The invention relates to the field of biomedical experimental equipment and specifically relates to an experimental box for an agar diffusion experiment. The experimental box comprises a box body and a plurality of functional plates arranged in the box body; a top wall and a side wall of the box body are open and are equipped with detachable top cover and side cover; a plurality of insert slots are respectively formed in the side walls on the two sides of the open side wall in the box body; the functional plates are detachably arranged in the box body in the manner of matching with the corresponding insert slots through the open side wall of the box body; the functional plates are composed of an agar bearing plate, a grid plate, a wet box plate, a constant temperature plate, an observing lining plate and a lamp plate. According to the invention, the instruments and equipment required by the agar diffusion experiment are gathered in the box body in the form of the functional plates; the structure is compact and the experimental box is portable; the functional plates can be instantly inserted through the insert slots formed in the box body, are free from mutual interference and are convenient to use.

Description

technical field [0001] The invention relates to the field of biomedical experimental equipment, in particular to an experimental box for agar diffusion experiments. Background technique [0002] Agar diffusion experiment is to add soluble antigen and antibody into small holes with a certain distance and pore size on the agar plate containing electrolyte, so that they can diffuse each other under certain conditions, and the two meet at a suitable ratio to form a white precipitation line (bring). When there are multiple antigen-antibody systems, multiple precipitation lines may appear, and then the antigen-antibody systems can be analyzed according to the number, position, and shape of the precipitation lines. It has high sensitivity and can be used as an auxiliary diagnosis for immune diseases. Clinically used for neonatal TORCH syndrome, chronic or subacute infection, malaria, infectious mononucleosis, mycoplasma pneumonia, liver disease, connective tissue disease, macrogl...

Problems solved by technology

Because the experimental conditions are higher than normal temperature, a constant temperature device is needed to assist, but the constant temperature device in the prior art is relatively large, and it needs to be turned on regardless of the number of people, resulting in a waste of resources

[0006] 3. The preferred concentration of agar in the agar gel plate of the agar diffusion experiment is 1%, and the rest is water. During the relatively high temperature experiment, the water is very easy to evaporate, which increases the concentration of agar and affects the antibody antigen on the agar gel plate. Diffusion in , thus affecting the experimental results

[0007] 4. In some agar diffusion experiments, the precipitation line obtained is thinner and shallower, and it is difficult to observe and interpret on the transparent agar plate. It is often necessary to take the agar plate out of the opaque plate and place it on a dark contrast lining plate to see

Not only the experimental process is complicated, but also when the agar plate is taken out from the plate, due to the soft and fragile characteristics of the agar plate, it is very easy to cause the cracking of the agar plate to affect the observation of the experimental results
