"20/20" SERIES

20/20 Series Multi-Well Gamma Counters (refurbished)
"The Gamma Counting System That Grows With Your Needs"

10 or 20 Multi-detector Counting Systems

The Model 20-10 has ten detectors, and the Model 20-20 has twenty detectors. Model 20-10 may be upgraded to twenty detectors as future needs require. Each model has variable windows. Two isotopes can be counted simultaneously. This Real Time data reduction system is extremely versatile, allowing the user a choice in processing data. The micro-computer offers the ultimate in data handling. Quality Control parameters may be chosen and stored for the various assays. Histograms, Levey-Jennings plots and other data may be printed. It is a very versatile RIA and quality control system.

Model 20/20 Series Gamma Counter Specifications:

Highest Throughput

This model is capable of counting 100 samples in less than 7 minutes. A traditional gamma counter would take nearly 2 hours to count the same group of samples.

Dual Label

Dual label assays are handled easily, since these counters allow the counting of two isotopes simultaneously.

Spilldown Correction

When counting dual label samples, there is usually a presence of the high energy isotope in the low energy window. This high energy, present in the low energy window, is automatically subtracted with spilldown correction.

Variable Windows

Both channel A and Channel B windows are user adjustable.

Normalization of Detectors

With the normalization program, all detectors can be matched to assure you of reproducible results year after year.

Disable Well

If for some reason, one or more detectors cannot be normalized, that detector can be taken out of service without influencing replicate samples. Since there are multiple detectors, there is no need to discontinue counting samples.

Accepts a Variety of Tube Sizes

We realize that all RIA tests are not done in 12x75mm tubes. The 20/20 Series Gamma Counters have the flexibility to accommodate many different size test tubes.

Counted Tube Storage

The 20/20 series counter will store up to 600 counted tubes for replay with various curves.

Display

LED display provides counts for each detector for both Channel A and Channel B, time and tray number

Dual External Ports

One port is for the terminal, the second port has been provided for interfacing with a central lab computer.
