Background

In the field of biochemical medicine, chemical experiments are often required. In the experiment, various reagent bottles, reflux pipes and other glass instruments are inevitably required to be connected. And the leakproofness to the kneck in general experiment requires comparatively highly, among the prior art, generally adopts dull polish to the kneck of glass instrument to handle, utilizes the concave-convex structure of dull polish face to cooperate and realizes sealedly. In the field of traditional Chinese medicine detection, some gas residual amount experiments such as sulfur dioxide residual amount detection and the like need to be carried out. In the experiment, sulfur dioxide or other gases exist in a gaseous state, so that the requirement on the sealing property is high, and the effect of sealing the gases cannot be effectively achieved by utilizing the frosted surface to realize sealing. Therefore, experimenters can coat materials such as paraffin and the like at the interface to enable the paraffin to fill the gap, and the sealing effect is achieved. But because often need heat the glassware in the experiment, the heating makes paraffin be heated and melts, can follow the kneck and flow downwards and get into the container in, influence the experiment precision.
