Key Use 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).
