Quality Control

Our Sulfur35 is produced and handled under strict quality systems. Each batch undergoes rigorous analytical testing, including radiochemical purity and specific activity determination, to ensure it meets the stringent requirements of research applications. A comprehensive Certificate of Analysis (COA) detailing radionuclidic purity, chemical form, and concentration is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a designated, shielded area appropriate for β-emitting isotopes at controlled room temperature (15-25°C). Due to its highly volatile nature in certain chemical forms (e.g., H235S), ensure containers are securely sealed and stored in a well-ventilated area with appropriate negative pressure or containment as per local radiation safety regulations.
