1. PP Syringe Filters

PP syringe filters are slightly hydrophobic and can be used as not only pre-filter but also terminal filter. PP membrane syringe filter is suitable for high-performance liquid chromatography sample filtration, gas separation, and Ion exchange chromatography sample filtration. Also, the 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
•Wide range of pore sizes with high porosity provided for selection
•Highly resistant to pressure and tolerant with the high-temperature sterilization
•Membrane 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

Applications of PP Syringe Filters

•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

2. Sterile PP Syringe Filters

Sterile PP syringe filters is a fast, convenient and reliable small-volume sample filtration processing device that is routinely used in laboratories. 5 micron syringe filter, 10 micron syringe filter all have the fast flow rates. Polypropylene syringe filters has high impact resistance, strong mechanical properties, and resistance to a variety of organic solvents and acid and alkali corrosion.

Features of Sterile PP Syringe Filters

•Hydrophobic PP syringe filter
•High solvent resistance
•Contains natural hydrophilic membrane
•10 micron syringe filter have wide compatibility with organic solvents
•Gamma ray disinfection and sterilization (more thorough and safer)
•5 micron syringe filter have low adsorption to large molecular proteins

Applications of Sterile PP Syringe Filters

•Ion chromatography
•Inorganic ion analysis
•HPLC sample preparation requiring low detection levels
