Filtration

Selecting Right Membrane Filter:

• Clearly define your application requirements
• Choose a compatible membrane
• Select the most effective and efficient pore size

Selecting Membranes for Your Applications:

• Determine the particle size to be retained or filtered. Membrane will retain all particles equal to and larger than their designated pore size.
• Assess the chemical compatibility of the membrane filter with the liquid or gas to be filtered.
• Consider the chemical resistance properties of all parts that will contact the filter.
• Consider hydrophilic or hydrophobic membrane; temperature, flow rate, throughput, and sterilization needs.

For Non-Filtration:

• Assess the interaction (e.g., adsorption or binding) of reagents to be used on the membrane with surface chemistry of the membrane.
• Determine the chemical compatibility (e.g., background intensity) of the membrane with reagents to be used.
• Consider hydrophilicity and hydrophobicity, strength, and pore size of the membrane for processability.
