Membrane-Solutions LLC's syringe filters are cost-effective products. The housing features a luer lock for the INLET and a luer slip for the OUTLET. Selection of Syringe Filters [1] Material of the membrane (filter part) 《Nylon / PTFE / PVDF / MCE / PP / CA / PES / GF》 Please choose based on the conditions such as hydrophilicity, chemical resistance, and application according to the sample you will use. [2] Pore size of the membrane 《0.10 to 5μm》*Depends on the type and diameter of the membrane. Please select according to the sample to be filtered. [3] Diameter (size) of the filter 《13mm / 25mm / 30mm》*Depends on the type and pore size of the membrane. Please choose according to the amount of the sample. [4] Some products are available sterilized and individually packaged. For more details, please refer to the catalog and materials. If you would like a sample, please use the "Sample Request Form" in the "Syringe Filter Comprehensive Catalog" or the "Sample Request Form" on the Osaka Chemical website.

**Features** ○ Nylon → Hydrophilic, suitable for both organic solvents and aqueous solutions ○ PTFE (Hydrophobic) → Resistant to organic solvents and acids/bases → Non-Pyrogenic, DNA-free ○ PTFE (Hydrophilic) → No hydrophilization treatment required for filtration of aqueous solvents such as acids and bases ○ PVDF → Hydrophobic → Extremely low protein adsorption, resistant to a wide range of organic solvents ○ MCE (Hydrophilic Mixed Cellulose Ester) → Hydrophilic → Excellent chemical resistance and heat resistance filter, achieving high throughput ○ Polypropylene → Hydrophilic with extremely low protein adsorption, resistant to a wide range of organic solvents → Refractometry, UV-VIS measurement ○ CA (Cellulose Acetate) → Hydrophilic → Extremely low protein binding, high throughput ○ PES (Polyether Sulfone) → Hydrophilic → High flow rate, low protein adsorption, suitable for various weak solvents and aqueous solutions ○ GF (Glass Fiber) → Hydrophilic, suitable for both organic solvents → Excellent resistance to organic solvents, highly contaminated liquids, and strong acids *Note: MS products are scheduled for a price revision starting April 2023.*
