Precision filtration infusion set material
May 25, 2018

Precision filter infusion material requirements are high. At present, there are mainly three kinds of filter membranes on the market. First, polyethersulfone membrane. The cost is high. The structure of the polyethersulfone membrane is divided into two layers of polyether sulfone membranes. The middle layer is made of polypropylene, so it has high adsorption and adsorption of drugs. Second, fiber membrane. The cost of the fiber membrane is relatively low, the fiber arrangement is disorderly, the aperture is irregular, and the filtration accuracy is low. Third, the nuclear membrane. The cost of the nuclear pore membrane is also relatively low, and the pores are easily connected, resulting in too large a filtration pore size and large particles passing through, resulting in unacceptable filtration rate. Fourth, ion membrane. The space distance and the pore size are uniform, and the hydrophobic membrane is not easily deformed and detached, and has low adsorption to drugs.
