Description

Filter Membrane 0.45um – Cellulose Nitrate Plane 47mm

Material:

• Cellulose nitrate (Cellulose ester): Provides good durability, chemical resistance, and works well with aqueous solutions (moderately hydrophilic).

Specifications:

• Diameter: 47 mm (standard size for filter holders)
• Pore size: 0.45 micrometers (µm) – allows passage of liquids and gases while trapping particles larger than 0.45 microns. This size is effective for filtering out bacteria but may allow some larger viruses to pass through.
• Membrane form: Flat (plane) – designed for use in filter holders or various lab techniques.

Applications:

• Sterilization of liquids (partial): Removes bacteria and some larger viruses from liquids, useful for applications requiring partial sterilization.
• Particle filtration: Effective in filtering particles like dust, debris, and precipitates from liquids or gases, commonly used in sample preparation, clarification, and particle analysis.
• Air filtration: Can remove airborne particles for applications requiring cleaner air environments or protecting equipment.
• Sample preparation: Helps prepare samples for analysis by removing unwanted particles that might interfere with techniques like microscopy or chromatography.

Considerations:

• Moderately hydrophilic: Works well with water-based solutions but may not be ideal for highly hydrophobic liquids. Consider PTFE or other membranes for such cases.
• Chemical compatibility: Verify the suitability of cellulose nitrate for the specific solvents you’ll be using.
