Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Because the traditional polymer synthesis process adopts single-stage filtration, the impurity filtration efficiency is low. The utility model provides an experimental funnel that suction filtration was used, based on the support supports, set up the barrel of feeding and set up a plurality of dry sieves in the barrel of feeding, arrange in proper order through the direction of height of a plurality of dry sieves along the barrel of feeding to fixed one deck filter paper on every sieve, and the aperture of every layer of filter paper is different, thereby establishes ties the filter paper in different apertures together, in order to satisfy the multistage filtration demand after the macromolecular material polymerization is accomplished.

The embodiment of the present invention will be described in detail by way of examples.
