About Disposable Syringe Filters

Disposable Nylon Syringe Filter Specifications

Material & Construction

• Membrane Material: Nylon (hydrophilic) suited for aqueous samples and many organic solvents. 

• Housing Material: Medicalgrade polypropylene (PP). 

• Hydrophilicity: Naturally hydrophilic typically no prewetting needed. 

 Dimensions

• Filter Diameters:

  • Common sizes: 4 mm, 13 mm, 25 mm, 33 mm, 50 mm 

• Connector Type:

  • Female Luer Lock inlet and Male Luer Slip outlet (standard syringe connection). 

Pore Sizes

• Typical Pore Sizes:

  • 0.1 m for fine filtrations (e.g., nearsterile sample removal)

  • 0.22 m bacterial removal / HPLC prep

  • 0.45 m general particle removal

  • 0.8, 1.0, 3.0, 5.0, 10.0 m coarse filtration options 

Performance Characteristics

• Filtration Area: Depends on diameter e.g., ~1.0 cm for 13 mm, ~4.3 cm for 25 mm.

• Maximum Operating Pressure: Typically ~56 bar (~7090 psi) for smaller filters. 

• Maximum Operating Temperature: Around 60100 C (autoclave capable). 

• Holdup Volume: Low e.g., <25 L for 13 mm, <100 L for 25 mm. 

• Bubble Point / Integrity: Manufacturers often specify minimum bubble point values to ensure membrane integrity (varies with pore size).
