The invention provides a temperature sensitive cell culture surface and preparation method thereof. The preparation method comprises the following steps: (1) preparing a temperature sensitive primary liquid by adding a temperature sensitive compound and a free radical into a solvent, mixing and dissolving the same, and obtaining the temperature sensitive primary liquid; and (2) distributing the temperature sensitive primary liquid on a cell culture surface, and leaving the cell culture surface at 50-150&#xb0; C. to react for 5-120 mins.

Temperature sensitive cell culture surface and preparation method thereof

A three-dimensional cell culture scaffold and preparation method thereof. The preparation method comprises the following steps: designing, according to a shape of a cell culture device, a shape of the three-dimensional cell culture scaffold; printing once by a 3D printer to form the three-dimensional cell culture scaffold; performing a surface treatment, by a surface treating agent, on the three-dimensional cell culture scaffold manufactured by 3D printing to obtain a resultant three-dimensional cell culture scaffold. By adopting a three-dimensional printing technology to manufacture a three-dimensional fibrous cell culture scaffold having a three-dimensional fibrous network structure, raw materials and a manufacturing time can be saved, reducing production costs, increasing production efficiency, decreasing power consumption, preventing a flaw in the conventional manufacturing technique, and facilitating large-scale intelligent manufacturing.

Three-dimensional cell culture scaffold and preparation method thereof

Provided are cell culture apparatus and method. The cell culture apparatus comprises a culture column and a perfusion system, the culture column comprising a first and a second tube-connecting caps and a support for cells to attach and grow thereon. The first and the second tube-connecting caps are respectively provided with a perfusion inlet and a perfusion outlet; The perfusion system comprises a culture medium storage device, a perfusion tube and a perfusion pump. A complete and closed culture column is formed in the cell culture device after the cells are inoculated, and the culturing is completed by the perfusion system to avoid contamination.

Cell culture apparatus and method

A dry-wet combined sorting system for municipal solid waste comprising a dry type smashing and winnowing device and a wet type water sorting device. The system is compact in structure; smashing knives with different revolving speeds and the same revolving direction are provided, thereby enabling continuous processing of the system which is high in processing efficiency and simple in operation; meanwhile, multiple protection devices are provided, so that the whole system is safe and reliable; perishable organic matters, light combustible matters and inorganic matters can be separated completely; the light combustible matters are picked out by the dry type smashing and winnowing device, which ensures their low water content and facilitates their subsequent energy-oriented utilization. Therefore, the municipal solid waste is into valuable thing for it can be utilized sufficiently as a resource, and the system has very high environmental benefits and social benefits.

Dry-wet combined sorting system for municipal solid waste

The invention discloses a system for squeezing, smashing and winnowing municipal solid waste (MSW). The system comprises a primary squeezing and smashing, device and a secondary smashing and winnowing device. The system of the invention has good effect m squeezing, smashing and winnowing, can greatly reduce the water content of MSW and efficiently separate the MSW into combustible matters and non-combustible matters, so as to facilitate further subsequent utilization of the municipal waste; moreover, an upper jaw of a jaw crusher is connected with a spring device, so that the squeezing pressure, smashing effect and processing capacity of the jaw crusher can be adjusted according to the amount of the MSW. In addition, the system of the invention is further provided with emergency brake switches, spring protection devices and a sieve, so as to ensure the stability and the reliability of the system.
