Problems solved by technology

[0002] At present, the funnel is one of the indispensable experimental instruments in the chemical laboratory. In chemical experiments, dripping or infusion operations are often encountered. Of course, ordinary operations can be performed through simple funnels. However, during the infusion process There will be glass funnel leakage or poor sealing, poor control, fast and slow, affecting the experimental results

Description

technical field [0001] The invention relates to the technical field of chemical experiment devices, in particular to an experimental funnel. Background technique [0002] At present, the funnel is one of the indispensable experimental instruments in the chemical laboratory. In chemical experiments, dripping or infusion operations are often encountered. Of course, ordinary operations can be performed through simple funnels. However, during the infusion process There will be glass funnel leakage or poor sealing, poor control, fast and slow, which will affect the experimental effect. Contents of the invention [0003] The invention provides an experimental funnel aiming at the deficiencies of the prior art. [0004] The solution of the present invention to solve the problems of the prior art is: an experimental funnel, including a liquid storage pipe and a gas pipe, the upper end of the liquid storage pipe is provided with an upper opening, the lower end of the liquid storag...
