Calibrated Test Tube Sources

These sealed test tube sources are manufactured by depositing radiochemical into the tube and evaporating. After drying, the activity is sealed inside the tube with epoxy. A cap is then secured. The test tubes are calibrated with a high purity germanium detector. Calibration certificates are provided.

License exempt in the United States.
International customers must check their local regulations for exemption limits.
