  • Traceable low activity solutions for calibration.
  • Calibrated traceable solutions – 7000-series or Isotrak
  • Non-calibrated solutions – 6000-series


7000 Series
Each nuclide is NIST traceable. Contained activity values have a ±15% relative to the requested activity value. The uncertainty of the measured activity for a NIST-traceable calibration can be ±3% at the 99% confidence level but will be no greater than ±5% unless otherwise noted. Manufactured in USA

6000 Series
Each isotope has a nominal contained activity of ±15%. Solutions are available in a variety of activities. Activity ranges for each nuclide are listed in the tables in the datasheet. Manufactured in USA.
