Calibrator Information

Quanti-Calibrators™, for checking I-125 and Co-57 Daily Performance on Gamma Counters since 1982.
 
Don’t introduce imprecision into your assays by using a Multi-Well Gamma Counter that is not properly calibrated.
These calibration check sources are sold as single 12x75mm tubes or as sets of up to 25 tubes matched to within 0.2% at 95% confidence interval, the tightest specification in the industry. They can be used to quickly identify when Normalization is required to bring Gamma Counter Detectors into agreement.
