This patent discloses an experimental feeding funnel, comprising: an inlet, a central feeding channel, and an outlet; the inlet is located at the upper end of the experimental feeding funnel; the outlet is located at the lower end of the experimental feeding funnel; the central feeding channel is a Venturi tube structure; the inner diameter of the central feeding channel is smaller than the inner diameters of the inlet and outlet; the inner diameter of the outlet is less than or equal to the inner diameter of the inlet; the outlet of the experimental feeding funnel is fitted onto the mouth of a suitable container for direct or indirect heating experiments for feeding. The experimental feeding funnel provided by this patent is easy to disassemble and clean, meeting both the experimental research needs of natural fragrance raw material extraction and the requirements of large-scale production. It solves the problems of clogging and inability to properly feed large-particle natural fragrance raw materials. The yield of finished fragrance products for tobacco extraction using this experimental feeding funnel is high, reducing waste of natural fragrance raw materials and environmental pollution.

The application relates to the technical field of gas-liquid separation, and discloses a pipeline type gas-liquid separation device suitable for a microgravity environment, which comprises a separator shell and a gas-liquid separation cylinder; the separator shell is located at the left side of the gas-liquid separation cylinder and is fixedly connected with the gas-liquid separation cylinder; gas outlet pipelines and gas-liquid mixture inlet pipelines are respectively arranged on the left and right side walls of the gas-liquid separation cylinder; a closed impeller is arranged on the head of the right side of the gas-liquid mixture inlet pipeline, and the closed impeller is located in the gas-liquid separation cylinder; the left side of the main body of the gas-liquid mixture inlet pipeline is located in the separator shell and rotationally connected with the separator shell, and shaftless guide vanes are arranged in the inner cavity; a metal wire screen and a liquid storage wire screen are arranged in the gas-liquid separation cylinder. The pipeline type gas-liquid separator under the microgravity environment has a larger separation capacity and a better separation effect than the traditional static separator, has the advantages of saving electric energy and simple structure compared with the traditional dynamic separator, and is suitable for the microgravity environment.

This invention discloses a hierarchical guanidine resin-based CO2 adsorbent material and its preparation method, belonging to the field of polymer synthesis technology. The adsorbent material prepared by this invention has a composite spherical structure and a hierarchical pore structure, including micropores, mesopores, and macropores. By introducing a hierarchical pore structure, the adsorption capacity of the material for CO2 is effectively improved. The introduction of hierarchical pores can significantly reduce molecular diffusion resistance and increase the contact area between the adsorbent and CO2 molecules, thereby achieving rapid adsorption. Furthermore, pyridyl, polyamino compounds, and guanidine groups have strong basicity and chemical affinity for CO2. Through surface functionalization modification, the number of active sites on the material surface is significantly increased, thereby further improving the CO2 adsorption capacity and selectivity.

The application discloses a multi-omics experiment device and experiment equipment. The multi-omics experiment device comprises a mounting seat, a pressing plate and a movable pressing block. The mounting seat is used for placing a microfluidic chip assembly. The pressing plate is used for covering the surface of the microfluidic chip assembly. The pressing plate is provided with a hollow structure. The hollow structure is arranged corresponding to a mark area of the microfluidic chip assembly. The movable pressing block is movably abutted against the upper surface of the pressing plate and is used for applying a pressing force to the pressing plate.
