Referring to fig. 4, the present embodiment provides an experimental apparatus, and the experimental apparatus of the present embodiment purifies, blows and the like, and is the same as the conventional experimental apparatus, except that a waste liquid recovery part is added, and the specific arrangement is as follows. The outer sleeve 4 is formed by recessing a corner of the table top in the experimental facility close to the push-pull show window and the side wall, and the rest of the structure is the same as that of the waste liquid collector.
The experimental facility embodiment that this application provided, the working process of waste liquid collection part is the same with above-mentioned a waste liquid collector.
The embodiment can show that the invention can realize the mass collection of waste liquid under the condition of occupying few table tops in experimental equipment, and greatly reduces the secondary pollution of the waste liquid to sterile materials and the pollution to the environment.
It should be noted that the waste liquid collector of this application can be used to super platform, and experimental apparatus can be super clean bench promptly, and the waste liquid collector of this application is not limited to and uses in super clean bench, and any place that needs to retrieve the waste liquid in the laboratory is all applicable. Referring to fig. 1 to 4, the arrangement and installation manner of the waste liquid collector of the present application are also applicable to collection operations of other small-scale generated waste liquids in laboratories except for super tables, and can be widely applied to areas such as fume hoods, common laboratories, and the like, and the application field of the waste liquid collector is not limited by the present application.
The preferred embodiments of the present application disclosed above are intended only to aid in the explanation of the application. The preferred embodiments are not exhaustive and do not limit the application to the precise embodiments described. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the application and the practical application, to thereby enable others skilled in the art to best understand and utilize the application. The application is limited only by the claims and their full scope and equivalents.
