The Packard Cobra II gamma counter is considered one of our core instruments. The series is available in single, five or ten detector configurations. All Cobra gamma counter models can count 12x75mm RIA tubes, 16x100mm and various smaller microtubes using an available adapter. (If you need help, please contact our expert technical team.)
All Cobra systems include LCD output, dot matrix printers, tube racks, protocol ID labels and operating manuals. Specific calculations include calibration curve display-, linear-, polynomial regression-, log-, logit-, 4pl-, automatic spline-, manual spline-, and cubic spline curve fitting algorithms.
Single detector models are available in 2-inch or 3-inch crystal configurations for research-grade capabilities. The system can accommodate pipes from 12mm to 16mm. GMI has the following models of the Packard Cobra range:
Packard Cobra Model 5002
Packard Cobra Model 5003
Packard Cobra Model 5005
Packard Cobra Model 5010
Our certification guarantees that all products meet the manufacturer's original specifications.
Packard Cobra Model 5002
This versatile model is ideal for research and everyday laboratory applications. System specifications include a single 2-inch sodium iodide (NaI) through-hole detector, 2000 KeV energy range and 750 sample capacity. The system includes a new LCD monitor, Epson printer and test tube cassettes. An optional instrument cart is also available. The Packard Cobra 5002 system is GMI certified, ensuring that original manufacturer specifications, including detector efficiency and crystal resolution, are maintained.
Packard Cobra Model 5003
The Cobra II 5003 is a true research grade gamma counter. System specifications include a 3-inch NaI through-hole crystal detector, 2000 KeV energy range and 750 sample capacity. This system is ideal for calculating low-energy activity and high-energy isotopes.
Packard Cobra Model 5005
The Cobra II 5005 is a multi-detector system with five 1.5-inch NaI through-hole detectors with an energy range up to 1000 KeV. With the ability to count 5 samples at a time, the 5005 is a suitable model for laboratories with high throughput requirements.
Packard Cobra Model 5010
The Cobra II 5010 is a 10 detector system that provides the highest throughput available. This model is capable of automatically counting up to 1000 RIA tubes. High-capacity systems, including the Model 5010, are ideal for use in large reference laboratories or research laboratories that can count large batches of short-lived isotopes, such as PET facilities.
