The Atomlab^™ 200 provides fast, accurate radionuclide activity measurements with performance that easily surpasses the most stringent regulatory requirements.

The unit is simple to operate. There are 13 isotope selection keys, 10 are pre-programmed for the most commonly used radionuclides and 3 are user defined. There are 94 isotope-specific dial values listed in the manual, including Y-90 and Sr-89. Any key can be reprogrammed by the user for a desired isotope.

Activity is displayed on a LED readout in either Curie or Becquerel units. Background correction and zero adjustment are performed at the touch of a button. Range selection is automatic.

Activity measurements are performed by a microprocessor controlled electrometer located within the detector assembly of the ionization chamber. The chamber is shielded with .25” (.64 cm) lead. It can be located up to ten feet away from the display unit. Chamber bias is generated within the display unit by an electronic high voltage supply, eliminating the need for expensive battery changes.

The Atomlab^™ 200 Dose Calibrator provides inventory management, quality assurance, and record-keeping functions. The dot matrix printer allows hard copy records to be produced for all functions. The microprocessor-driven memory provides inventory control for 25 samples, storing and correcting the volume, activity, and moly concentration. When drawing a dose from an inventory sample, the Atomlab^™ 200 will display the required volume for a specific dose and, if required, print a decay chart showing required volumes for that dose at future times.

The Atomlab^™ 200 facilitates dose calibrator quality assurance with automatic constancy and linearity functions. The system stores and decay corrects Co-57 and Cs-137 reference sources and compares the measured activity to the calculated activity for the daily constancy test. Quarterly linearity tests are simplified by software which guides the user through the attenuator tube procedure (regardless of which brand you use), stores all values, and does all calculations.

For radiopharmaceutical quality control, the Atomlab 200 performs all counting and calculations for paper chromatography tests, computing the percentages of free pertechnetate, hydrolyzed reduced Tc-99m, and labeled radiopharmaceuticals.

The RS-232 port enables the Atomlab^™ 200 Dose Calibrator to communicate with most commercially available nuclear medicine management systems.

An industry exclusive two-year warranty is standard.
