Filtstar series PP syringe filters are slightly hydrophobic and can be used as not only pre-filter but also terminal filter. These syringe filters are suitable for organic solvents but cannot be used in strong organic solvents, especially aromatic and chlorinated solvents.
PP membrane syringe filter is suitable for high-performance liquid chromatography sample filtration, gas separation, and Ion exchange chromatography sample filtration. Also, PP syringe filters could effectively bind proteins, DNA, and RNA. Moreover, PP syringe filters could meet the requirement of the filtration of aqueous and organic solutions. It could also be applied in the production of photoresist materials.
The diameter of the filter ranges from 4mm to 50mm, of which 25mm syringe filters are the most widely used.
Features of PP Syringe Filters
•Hydrophobic microporous membrane syringe filter
•Large capacity for dirt and pollutants
•Stable physical and chemical properties
•Good pre-filtration syringe filters
•Without any additives in the whole process of production
•Wide range of pore sizes with high porosity provided for selection
•Highly resistant to pressure and tolerant with the high-temperature sterilization
•Good chemical stability and good chemical compatibility in both aqueous and alcoholic solutions
•Film material for deep filtration, which uses food-grade isotactic polypropylene as a raw material
Advantages of PP Syringe Filters
•Eliminates loss of sample and time
•Ideal for autosampler vials and NMR tubes
•Comprehensive pore size from 0.1μm to 10μm
Applications of 22mm, 45mm PP Syringe Filters
•Inorganic ion analysis
•Aromatic and chlorinated solvents
•Aqueous or organic solvent filtration
•Incompatible with Hexane, benzene, limited resistance to dichloromethane and chloroform
•Same as hydrophobic PTFE syringe filters, 25mm PP syringe filters is ideal for HPLC sample preparation
