0.22 µm PES syringe filters

Description

Sterile filtration accessories for peptide and laboratory research

0.22 µm PES (polyethersulfone) syringe filters are widely used in laboratory and research environments for sterile filtration and particulate removal. They are commonly applied during peptide reconstitution, solution transfer, and clarification steps to reduce microbial contamination and improve solution purity.
These filters feature a Luer lock connection for secure attachment, while remaining fully compatible with standard Luer slip (non-lock) syringes, providing flexibility across different laboratory setups.

Key benefits (anecdotal & research-based)

Effective removal of bacteria and particulate contaminants from solutions.
Low protein-binding PES membrane minimizes peptide loss during filtration.
Improves clarity and consistency of reconstituted peptide solutions.
Helps extend usability of filtered solutions when combined with sterile handling.
Widely adopted standard in peptide, biochemical, and analytical laboratories.

Why choose our 0.22 µm PES syringe filters

High-quality PES membrane designed for peptide and protein work.
Secure Luer lock connection with added compatibility for standard syringes.
Individually packaged to maintain sterility until use.
Reliable performance in routine laboratory and research applications.

Suggested use

Application: sterile filtration of peptide solutions, buffers, and laboratory reagents.
Typical workflow:
Reconstitute peptide using sterile technique.
Attach filter to syringe (Luer lock or slip).
Slowly filter solution into a new sterile vial.
Best practice: use a new filter for each solution to avoid cross-contamination.
Handling note: apply gentle, steady pressure to prevent membrane damage or peptide loss.
