Recommend a few precision infusion sets. Beijing Yushen, Shandong Weigao, Guangzhou Dayu, Shanghai Jinta, what else? Which one is better? What's good about it?

Recommend Yushen's. The filtration membranes used in Weigao's are polyethersulfone. The filtration membranes used in Weigao are polyethersulfone membranes and fiber membranes. These two membranes are more common, not good, his pore size arrangement is irregular, not close enough. Moreover, when soaked with drugs, the fibers will fall off, which affects the infusion effect and makes it difficult to do precise infusion. This kind of membrane can not be used in gravity infusion and viscosity of the drug. It is generally used for pressure infusion. And Yushen's ionic membrane microporous filtration membrane has good permeability, stable performance, drug adsorption rate of only 2.86%, smooth surface, no polymer material shedding, minimal self-pollution, pore size does not change by the drug immersion, always maintain filtration precision, far superior to the commonly used fiber membrane material.
