Before analyzing the samples, the service life of chromatographic column will be extended dramatically through filtering the particles in the samples.
In selection of syringe filter, the property of materials should be first considered, that is, whether the syringe filter is acid-resistant, alkali, organic solvents and so on. There are some brief introductions on materials manufactured for syringe filters.
PVDF Materials
PVDF syringe filter made of this material has high mechanical strength, good tensile strength, good heat resistance and chemical stability, very low protein adsorption, strong hydrophobicity. Applications: gas and steam filtration, high temperature liquid filtration, tissue culture medium, additives and other sterilization filtration, solvent and chemical raw materials purification filtration.
Nylon Materials
Syringe filter made of this material has good temperature resistance, can withstand 121°C, saturated steam high pressure disinfection 30 minutes, the maximum operating temperature 60°C, chemical stability good resistance to dilute acid dilute alkali and other organic and inorganic compounds, solvents. Application: Suitable for filtration of water filtration in electronics, microelectronics, semiconductor industry, tissue culture medium, liquid medicine, beverage, high purification chemical, water and organic solution mobile phase.
PTFE Material
PTFE syringe filter made of this material has a wide range of chemical compatibility, good temperature resistance, strong acid and alkali resistance, strong chemical corrosive solvents and oxidants. Applications: Chemical, pharmaceutical, environmental protection, electronics, food, energy and other fields, can filter almost all organic solutions.
Advantage of syringe filter
Syringe filter PVDF material: high mechanical strength, good tensile strength, good heat resistance and chemical stability, extremely low protein adsorption, strong hydrophobicity.
Syringe filter PES material: extremely low protein adsorption and very high protein recovery. Fast flow rate and high filtration speed. Good solvent resistance, suitable for many applications.
Syringe filter MCE material: mixed cellulose is a mixture of cellulose acetate and nitrocellulose. It has no biological activity and good hydrophilicity. It is widely used in clarification and sterilization filtration of various liquids. One of the microporous filter membranes.
Syringe filter Nylon material: good temperature resistance, good chemical stability, resistance to various organic and inorganic compounds and solvents such as dilute acid and alkali. Natural hydrophilicity, no wetting agent is needed during use, and the filter fluid is not contaminated.
Syringe filter PTFE material: suitable for gas sterilization, aseptic device gas exchange, vacuum pipeline protection, organic solution sterilization or clarification filtration. It can be applied to instruments such as carbon dioxide incubators, laboratory fermentation tanks, etc. It can also be used as a protector for vacuum pumps to prevent liquid from flowing backwards and causing damage to the pump. Different material disposable needle filters to meet different needs.
Syringe filter PVDF material: high mechanical strength, good tensile strength, good heat resistance and chemical stability, extremely low protein adsorption, strong hydrophobicity.
