• Dose Calibrator Sources “S” vial Dual Geometry Products

"The new Gold Standard for Ion Chamber Accuracy"


All Dose calibrator "S" vials are calibrated against a traceable National Institute of Standards and Technology (NIST) solution, in an identical geometry, using a pressurized ion chamber.

This patented source design mimics a "4cc" syringe or 10 CC multidose vial and allows for the use in either the syringe or vial positions on your dose calibrator dipper. It enables accurate measurement by minimizing both the physical geometry and position geometry effects thereby maximizing your ion chamber accuracy. Each source is packaged in an individual lead shield that is color coded to the source. Red/Co-57, Green/Cs-137 and Black/Ba-133.

All sources are shipped with a Certificate of Calibration, Leak Test Certification, radiation safety and handling instructions and a custom decay calendar.
