Pharmaceutical microporous membrane

Pharmaceutical microporous membrane

application

This product is mainly used for filtering mobile phases and samples in chromatographic analysis, and has a good effect on protecting chromatographic columns, infusion pump tubing systems, and injection valves from contamination. Widely used in weight analysis, microanalysis, colloid separation, and sterile testing. During use, select the appropriate filter membrane based on the sample being filtered.

Product Introduction

In the application of membrane separation technology, microporous membrane is a widely used type of membrane, which is easy and fast to use. It has the characteristics of high gas flux, high particle retention rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, aging resistance, non stickiness, non flammability, non toxicity, and good biocompatibility. Its materials are divided into two categories: organic and inorganic. Considering the separation characteristics of microporous membranes, their application scope is mainly to intercept particles, bacteria, and other pollutants from gas and liquid phases, in order to achieve purification, separation, and concentration. For microfiltration, the retention characteristics of the membrane are characterized by its pore size, which usually ranges from 0.1 to 1 μ m. Therefore, microfiltration membranes can separate large-diameter bacterial cells, suspended solids, etc. Can be used for clarification, security filtration, and air sterilization of general liquids. Widely applied in scientific research, medicine and health, biochemistry, food, energy, microelectronics industry, nanotechnology, environmental protection and other departments.

Characteristics and Applications

Imported Nylon 66

Features: Imported film from the UK, originating from the British Film Company in 1948, with superior performance to domestically produced nylon 6. It has good hydrophilicity, high strength, high flow rate, high porosity, and is suitable for the majority of machine solvents and aqueous solutions with high flux. It has high quality resistance, high temperature resistance, acid resistance to aqueous solutions and organic solvents, and high surface quality. The film material has a wide range of drug compatibility, wide applications, low dissolution rate, and stable chemical properties.

Application: Liquid clarification, sterilization filtration, and particle filtration
High pressure, ethylene oxide and other sterilization methods can be used

Imported Polyether Sulfone (PES)

Features: Imported from Germany, originating from the German membrane company in 1965, hydrophilic membrane with high chemical and thermal stability, strong acid and alkali resistance (pH range 1-14), and high mechanical strength. High flux and high flow rate. Currently, the membrane with high filtration rate is polyethersulfone, while the membrane with low protein binding capacity is the best choice for ion chromatography due to its high protein adsorption capacity, which can improve protein recovery rate. It has a wide range of medicinal compatibility, low dissolution rate, and can be sterilized by high temperature and high pressure (30 minutes, 121 ℃), ethylene oxide and other methods.

Application: Filtration of biologics and serum in the pharmaceutical industry, terminal filtration of antibiotics, etc
Food industry beverage, alcohol and other terminal filtration, super storage water terminal filtration

Polytetrafluoroethylene (PTFE)

Characteristic: Imported from the United States, originating from the American Film Company in 1915. Hydrophobic membrane, after treatment with ethanol or isopropanol, becomes hydrophilic membrane. Hydrophobic membrane cannot be naturally wetted, while hydrophilic membrane can be naturally wetted. High temperature resistance, strong acid and alkali resistance, good chemical compatibility with organic solvents and oxidants, and resistance to the vast majority of chemical solvents.

Application: Used for sterilization and filtration of water and solvents
Gas sterilization filtration and vacuum filtration
Electronic industry high-purity gas filtration
Steam filtration
Aseptic exhaust filtration for fermentation tanks, storage tanks, and ingredient tanks in the food industry

Mixed Cellulose (MCE)

Characteristics: The membrane material has a smooth surface, light and thin texture, high porosity, good retention effect, good hydrophilicity, high water flux, uniform microporous structure, and extremely low adsorption rate. It is not resistant to organic solutions and strong acid and alkali solutions, and can withstand pH values of 2-9 during filtration. It is only suitable for filtering water-based drugs or other water solvents, with high cost-effectiveness.

Application: Sterilization and particle removal in laboratory and small-scale production processes
Sterilization and filtration of culture medium and medium
Determination of microbial communities in water bodies

Polypropylene (PP)

Characteristics: Deep filtration, stable physical and chemical properties, good compatibility, high porosity, large pollutant capacity, capable of backwashing and high-temperature disinfection, good pressure resistance.

Application: Filtration of biomacromolecule precipitates
Pre filtration before filter membrane

Polyvinylidene fluoride (PVDF)

Characteristics: Hydrophobic membrane, non hygroscopic, turns into hydrophilic membrane after treatment with ethanol or isopropanol, extremely low protein adsorption rate, resistant to chemical corrosion and oxidation.
