CleanMark gamma labels are built with chemical indicators to help identify products that have successfully completed a radiation sterilization process. These sterile indicating labels play an important role in ensuring that medical devices and pharmaceuticals are marked clean and safe for use after receiving an appropriate dose of gamma irradiation. Our gamma labels are made with radiation sensitive material which consistently and permanently changes color from yellow to red when exposed to gamma irradiation. This color change is immediate and easily seen upon exposure to gamma dose levels in excess of 10 kGy. CleanMark can provide gamma labels for a wide variety of primary and secondary packaging applications. We have you covered with label solutions for small PCR tubes up to large cardboard boxes. For sterile production that occurs in cleanrooms, like aseptic filling processes, CleanMark can manufacture gamma labels with synthetic materials and clean / package them in our Class 100 cleanroom so that they will not shed particulates and contaminate your controlled environment.
