FAQ

What is the shelf life of this filter?

The filter remains effective indefinitely if the sterile packaging is intact, but it is recommended to use it within standard laboratory guidelines to ensure optimal performance.

Can I autoclave this filter for reuse?

No, this filter is designed for single-use only to maintain sterility and prevent cross-contamination, as autoclaving may compromise the membrane integrity.

What applications is the 0.22μm pore size best for?

The 0.22μm pore size is ideal for sterilizing solutions by removing bacteria and fine particulates, commonly used in cell culture media and critical bioprocessing steps.

Is this filter compatible with all bottletop dispensers?

Yes, it is designed to fit standard bottletop dispensers, but always verify compatibility with your specific equipment to ensure a secure connection.

How does the PES membrane benefit filtration?

The PES membrane offers high flow rates, low binding of proteins and biomolecules, and excellent chemical resistance, making it suitable for sensitive biological samples.
