Technetium Generator

SDS GEN (99Mo-99mTc Radionuclide Column Generator Dry Type)



Parent nuclide: Sodium molybdate (Na99MoO4) 7.5-30 GBq per generator (Mo-99 radioactivity at calibration date)

Daughter nuclide: 99mTc- Sodium pertechnetate (Na99mTcO4) derived from 99Mo/99mTc generator system


"SDS GEN” is a 99Mo-99mTc generator, containing a glass column, filled with acidic aluminium oxide (Al2O3), on which fission Molybdenum-99 (Na299MoO4) is adsorbed. The column is placed inside lead shielding, which assures the protection against radiation and safe use.

Generator is equipped with microbiological filter which assures sterility of the eluate when stored under proper conditions. Elution time varies from 3 minutes for eluate volume 4.0 ml to up to 5 minutes for eluate volume 10.0 ml.

The column is dried by air flow after the elution is finished. Leaving the column in a dry state prevents water radiolysis which would increase generator’s efficiency and quality of eluate.

Technetium 99m (99mTc) formed by the decay of 99Mo, is a radioactive isotope having a half-life of 6.007 hours. After eluting by 0.9% NaCl solution, 99mTc Sodium Pertechnetate solution which is isotonic, colorless, clear, sterile, non-pyrogenic and suitable for I.V. injection is obtained. (99mTc) Sodium Pertechnetate solution can be administrated to the patients directly as a diagnostic agent or for labeling the kits.
