Test tube sources are designed for use as reference sources in well type detectors or clinical instruments. Each source is constructed using a capped 12 mm x 75 mm polypropylene tube.

The source material is deposited in the bottom of the tube and sealed using epoxy.

All test tube sources have an uncertainty of ± 20% of the labeled activity unless calibrated (± 5%) for an additional cost.
