High temperature resistant laboratory filter membrane

High temperature resistant laboratory filter membrane

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.

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.

Characteristics and Applications

Imported Nylon 66

characteristic:Imported film from the UK, originating from the British Film Company in 1948, outperforms domestic nylon 6 in terms of performance. 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, 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)

characteristic:German imported film, originating from the German film company in 1965, is a hydrophilic film 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:Pharmaceutical industry, including biological and serum filtration, antibiotic terminal filtration, etc
Food industry beverage, alcohol and other terminal filtration, super storage water terminal filtration

Polytetrafluoroethylene (PTFE)

characteristic:The imported film from the United States originated from the American Film Company in 1915. It is a hydrophobic film that is treated with ethanol or isopropanol to become a hydrophilic film. Hydrophobic films cannot be naturally wetted, while hydrophilic films 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

Polypropylene (PP)

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

Application:Filtration of biomacromolecule precipitates
Pre filtration before filter membrane

Polyvinylidene fluoride (PVDF)

characteristic:Hydrophobic membrane, non hygroscopic, transforms into hydrophilic membrane after treatment with ethanol or isopropanol, with extremely low protein adsorption rate, chemical corrosion resistance, and oxidation resistance.

Application:Western and Southern transfer and protein sequencing
Protein solution, tissue culture medium, antibiotics and other liquid sterilization filtration
Removing particles with solvents such as acids, alcohols, alkanes, aromatic hydrocarbons, halogenated hydrocarbons, etc
Purification of suspended particles in the air and air sterilization in the fermentation industry
Purification of insoluble substances in oils and weight analysis of solid particles
Biological testing TCA precipitation
Sterilization can be carried out using methods such as high temperature and high pressure (30 minutes, 121 ℃) or ethylene oxide

Mixed Cellulose (MCE)

characteristic:The surface of the membrane material is smooth, the texture is light and thin, the porosity is high, the retention effect is good, the hydrophilicity is good, the water flux is large, the microporous structure is uniform, and the adsorption rate is extremely low. It is not resistant to organic solutions and strong acid and alkali solutions, and the filtration can withstand pH values of 2-9. It is only suitable for the filtration of 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
