A New Automatic TDCR Liquid Scintillation Counter released
A new day of liquid scintillation counting is dawning...
Based on experience of close to 1500 scintillation counting systems installed, Hidex is proud to present the 300SL automatic TDCR liquid scintillation counter.
The new reader has automatic sample loading of various vial sizes. It includes a revolutionary Triple to Double Coincidence Ratio measurement feature that enables easy and straightforward determination of sample efficiency with out any external or internal source of radioactivity.
Alpha/Beta separation, Temperature control, external standard and low level counting mode are all optionally available.

Triathler is a unique tool for scientists involved in biotechnology, medicine, life science, and environmental monitoring. It's a small, manual single-well instrument for liquid scintillation counting, gamma counting and luminescence counting.
Portability
Due to Triathler's extremely small size and light weight the counting is easy to perform in the field, wherever you collect your samples.
Unmatched flexibility
Triathler's interchangeable adapters accept most types and sizes of vials.
True ease of operation
Place the vial in the adapter. Close the cap and press a selection key to start. Read the results on the display and export to PC or print out directly.
Triathler is available as several different models: LSC, gamma counter, luminometer and multilabel counter.

A gamma ray interacting with a scintillator produces a pulse of light that is converted to an electric pulse by a photomultiplier tube (PMT). The PMT consists of a photocathode, a focusing electrode, and 10 or more dynodes that multiply the number of electrons striking at each dynode. A chain of resistors typically located in a plug-in tube base assembly biases the anode and dynodes. Complete assemblies including the scintillator and PMT are available.
The properties of a scintillation material required to produce a good detector are transparency, availability in large size, and large light output proportional to gamma-ray energy. Few materials have good properties for detectors. Thallium-activated sodium iodide [NaI(Tl)] and cesium iodide [CsI(Tl)] crystals are commonly used, as well as a wide variety of plastics. CsI(Tl) and plastics have much faster light decay times than NaI(Tl) and are primarily used for timing applications.
The high Z of iodine in NaI(Tl) crystals result in high efficiency for gamma-ray detection. Resolution for a 3-inch diameter by 3-inch length crystal is typically about 7% for 137Cs and slightly worse for larger sizes. The light decay time constant for a NaI(Tl) crystal is about 0.23 µs. Typical charge-sensitive preamplifiers translate this into an output voltage pulse with a rise-time of about 0.5 µs. Fast coincidence measurements cannot achieve the very short resolving times that are possible for plastic scintillators, especially at low gamma-ray energies.

Features
Guaranteed resolution
Low mass housing
Less than 0.5 ppm of potassium
Mu metal magnetic light shield
Description
The Model 802 Scintillation Detector is a hermetically sealed assembly which includes a high resolution NaI(Tl) crystal, a photomultiplier tube, an internal magnetic/ light shield, an aluminum housing, and a 14-pin connector.
The 802 series of NaI(Tl) detectors provides high efficiency and uniform response on both the cylindrical and well configurations. These detectors have a proven record of long term reliability and stability.
Any Model 802 assembly plugs directly into the Model 2007 Tube Base which provides power for the photomultiplier tube. Alternatively, the Model 802 can plug into the Model 2007P combination tube base and preamplifier.
Many crystal sizes are available, with the most common sizes listed below. Consult the factory for information on other sizes.
