47mm&50mm Microporous Filter Membrane, Ф47, 0.2/0.45μ, PVDF, Tianjin Jinteng Experimental Equipment Co.,Ltd. (CAT#: STEM-L-0146-YJL)

47mm&50mm Microporous Filter Membrane, Ф47, 0.2/0.45μ, PVDF, model STEM-L-0146-YJL, is manufactured by Tianjin Jinteng Experimental Equipment Co.,Ltd. In the application of membrane separation technology, microporous membrane is the most widely used type of membrane, which is simple and quick to use. It has the characteristics of large gas flux, high particle retention rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, aging resistance, non-stick, non-flammable and non-toxic, and good biocompatibility. Its materials are divided into two categories: organic and inorganic. In view of the separation characteristics of microporous membranes, the application scope of microporous membranes is mainly to intercept particles, bacteria and other pollutants from the gas phase and liquid phase to achieve the purpose of purification, separation, concentration. For microfiltration, the retention characteristics of the membrane are characterized by the pore size of the membrane, which usually ranges from 0.1 to 1 μm. Therefore, the microfiltration membrane can separate large-diameter bacteria and suspended solids. It can be used for clarification, security filtration and air sterilization of general liquids. It is widely used in scientific research, medicine and health, biochemistry, food, energy, microelectronics industry, nanotechnology, environmental protection and other departments.

Specification: Ф47 0.2/0.45μ
Material: PVDF
Package: 100 pcs/pack

Imported nylon 66 (Nylon66)
Features: British imported membrane, from the British membrane company in 1948, better than domestic nylon 6 performance. It has good hydrophilicity, high strength, high flow rate, high porosity, and is suitable for most organic solvents and aqueous solutions, high flux, high quality, high temperature resistance, acid aqueous solution and organic solvent resistance. The film material has high surface quality, broad drug compatibility, wide application, low dissolution rate and stable chemical properties.
Imported polyethersulfone (PES)
Features: Germany imported film, from the German film company in 1965. It is a hydrophilic membrane with high chemical and thermal stability, strong acid and alkali resistance (pH range 1-14), and high mechanical strength. It has a large flux and a high flow rate. At present, the highest membrane speed is polyethersulfone, which is the membrane with the lowest protein binding capacity. Because of the protein adsorption capacity, it can improve the protein recovery rate. It is the best choice for ion chromatography. It has a wide range of medicinal compatibility and the lowest dissolution rate. bacteria.
Polytetrafluoroethylene (PTFE)
Features: The film imported from the United States originated from the American Film Company in 1915. It is a hydrophobic membrane, which becomes a hydrophilic membrane after being treated with ethanol or isopropanol. The hydrophobic membrane cannot be naturally wetted, while the hydrophilic membrane can be naturally wetted. It is resistant to high temperature, strong acid, strong alkali, organic solvents and oxidants, and has good chemical compatibility, and is resistant to most chemical solvents.
Polyvinylidene Fluoride (PVDF)
Features: Hydrophobic membrane, does not absorb moisture, and becomes a hydrophilic membrane after being treated with ethanol or isopropanol. It has extremely low protein adsorption rate, chemical corrosion resistance and oxidation resistance.
Mixed Cellulose (MCE)
Features: The membrane material has smooth surface, light and thin texture, high porosity, good retention effect, good hydrophilicity, large water flux, extremely low uniform adsorption rate of microporous structure, and is not resistant to organic solutions and strong acid and alkali solutions. The filtration is resistant to pH 2-9, and it is only suitable for the filtration of liquid medicines or other water solvents, and it is cost-effective.
Polypropylene (pp)
Features: deep filtration, stable physical and chemical properties, good compatibility, high porosity, large dirt holding capacity, recoil and high temperature disinfection, good pressure resistance.
