Introduction to PES Syringe Filter 13mm 0.22µm
Polyethersulfone (PES) syringe filters with a 13mm diameter and 0.22µm pore size are widely used in laboratory settings for sterile filtration of small-volume aqueous samples, such as peptide solutions (e.g., PE-22-28, AICAR, Selank), buffers, and culture media. These hydrophilic filters offer low protein binding, high flow rates, and excellent chemical compatibility with aqueous solutions and mild organic solvents.
Benefits of PES Syringe Filter 13mm 0.22µm
PES syringe filters are valued for their performance in laboratory applications:
Sterile Filtration: The 0.22µm pore size removes bacteria and fine particles, achieving a log reduction value (LRV) >7 for microbial challenge tests (e.g., ATCC 19146), ensuring sterile solutions (Amazon SimPure).
Low Protein Binding: Ideal for filtering peptide solutions (e.g., PE-22-28) without significant loss of active compounds (Filtrous).
High Flow Rates: Asymmetric PES membrane structure enables fast filtration, reducing pressure and time required (Cobetter).
Chemical Compatibility: Suitable for aqueous solutions and mild organic solvents (pH 3–12), though incompatible with strong acids, MEK, or DMSO (Hawach).
HPLC Sample Preparation: Ensures particle-free samples for chromatography, protecting equipment and improving accuracy (Scharlab).
