Bio-Safe™ columns are “biocompatible” and precision-machined from virgin PEEK™ (polyetheretherketone), a strong, inert polymer material, and are metal free for biotechnology and ion chromatography applications. PEEK columns are used when analytes are sensitive to the metals in stainless steel hardware. Proteins, peptides, and ions may have this susceptibility. PEEK is also compatible with most mobile phases used in HPLC. While THF will cause PEEK to swell, this is generally limited to PEEK capillary tubing <1.0 mm ID.
