SEASTAR™’s BASELINE® High Purity Fluoropolymer Bottles have become popular due to the drive for lower detection limits in trace metal analysis. As with our other products, this requires improvements in all aspects of the analytical process including how samples and reagents are handled and stored. Fluoropolymers have gained widespread acceptance for use in trace analysis because of the combination of chemical resistance and perceived purity. However, Fluoropolymer bottles and labware can contain significant amounts of metallic impurities from both the resins and manufacturing process. In general, virgin Fluoropolymer PFA and FEP resins are better than PTFE in terms of metal impurities, but even bottles and labware manufactured from the best virgin resins and exhaustively pre-cleaned prior to use can contain impurities which will compromise acid solutions at the sub-ppb level.
SEASTAR CHEMICALS Inc has worked together with our bottle supplier to investigate the sources of this contamination and ways to remove it from the manufacturing process and in subsequent cleaning procedures. This effort has resulted in a significantly cleaner line of Fluoropolymer PFA and FEP bottles. Bottles are specially manufactured by our bottle supplier to SEASTAR™’s specifications and pre-cleaned by SEASTAR™ to reduce leachable metals, packaged in a clean room environment and ready for immediate use in your trace metal applications.
