Just like the USP, we here at ERA demand scrupulously cleaned vials for our Total Organic Carbon (TOC) standards. All of our vials, whether glass or polymer, represent the most consistently clean sample vials available anywhere. They are the perfect vial for your purified water (PW) or water for injection (WFI) sample analysis. In addition to ultra-low level TOC Vials, ERA offers 60 mL HDPE Bottles for Anatel A643 and 30 mL Poly vials for Sievers 400. *Anatel is a registered trademark of the Hach Company. Sievers is a registered trademark of GE Analytical Instruments.
