Sterile Syringe Filter PES 0.22 µm, 13 mm
High-quality sterile syringe filter designed for laboratory and research use, including peptide solution preparation where microbial contamination is a concern.
This 13 mm filter features a 0.22 micron pore size polyethersulfone (PES) membrane, widely used in laboratories for fine particulate and bacterial reduction during solution clarification. PES membranes are known for low protein binding, high flow rates, and chemical compatibility with aqueous peptide solutions, helping preserve yield while improving solution clarity.
Key Features
• 0.22 µm pore size for fine particulate and bacterial reduction
• 13 mm diameter, suitable for small volume peptide preparations
• Low protein binding PES membrane to minimize peptide loss
• Individually sterile and ready to use
• Compatible with standard Luer lock and Luer slip syringes
Application in Peptide Preparation
When reconstituting or transferring peptide solutions, sterility may be compromised due to handling, environmental exposure, or raw material uncertainty. Passing the solution through a sterile 0.22 µm PES syringe filter can significantly reduce microbial and particulate load, supporting cleaner preparations prior to aliquoting or storage.
This filtration step is commonly used in research workflows to improve solution quality and reduce contamination risk when formal sterility testing is not available.
Important Notice
Filtration through a 0.22 µm membrane reduces the risk of bacterial contamination but does not guarantee sterility and does not replace validated sterility testing procedures. Proper aseptic technique remains essential.
Suitable for laboratory and research use only.
