The most advanced, transportable and user-friendly LSC on the market


The Hidex 300 SL is a revolutionary instrument which incorporates the most advanced technology available, triple-to-double coincidence ratio (TDCR) counting. TDCR utilizes a unique design with three photomultiplier detectors aligned 120 degrees from each other, which offers superior efficiency and counting results for both advanced research and environmental work.


The 300 SL has a modern and compact design measuring half the size and weight of some of its long standing rivals. It is therefore much easier to fit it into smaller, more space conscious laboratories, such as transporting in research vessels or mobile labs.

Super Low-Level Model

Similar to the standard instrument the Hidex 300 SL super low-level scintillation counter is equipped with additional lead shielding, low-level PMT detectors, and an active guard detector for further background reduction.

Ideal for 3H in water measurements, other low-level environmental monitoring, radiocarbon dating and biofuel verification.

New Active Guard
The Active Guard is a separate scintillator detector which measures and subtracts real-time background radiation. The guard can be turn off for high energy samples and does not interfere with alpha/beta separation.

TDCR Technology

The 300 SL utilizes a unique design with three photomultiplier detectors aligned 120 degrees from each other, which offers superior efficiency and counting results for both advanced research and environmental work.

In addition, the 300 SL can be used in triple coincidence mode only, which removes interference from chemiluminescence and the need to dark adapt. The counter can also be operated in dual coincidence mode using conventional standards and quench correction methods.

Quench curves can be generated and stored within the MikroWin software, which can be automatically applied or manually fitted to recalculate previous data.

Detector Design

Optimal Lead Shield Design

A minimum of 70 mm lead in all directions provides excellent shielding and minimizes instrument weight.

Lead Shutter
Reduces cosmic radiation.

Copper Shielding
Eliminates X-rays from lead shield.

Measurement Chamber
Highly reflective proprietary paint maximizes photon detection.

Robotic Loading Arm
Removes the need for a complex elevator mechanism, preventing jams, and is easily serviceable.

Three PMTs detectors in coincidence mode provide optimal counting geometry and facilitate TDCR calculations.

No internal or external standard source

The TDCR method allows easy determination of sample counting efficiency without the use of any internal or external standard source of radioactivity, offering many benefits for the modern lab including no hidden disposal costs, no health hazard when servicing, and no transportation restrictions.


  • Temperature Control Module
  • Alpha/Beta Separation Module
  • Low-Level PMT Detectors
  • Digital Lead Shield
  • External EU-152 Standard

The 300 SL uses an external PC which is Windows 7 and 8 compatible, enabling several users to transfer their method and data files to other offline or networked PC’s.

The MikroWin 300 SL software features an easy-to-use graphical interface and advanced data reduction capabilities. An unlimited number of protocols, easy export to Excel™, custom calculations and quench curves are all included. MikroWin also has options for 21 CFR Part 11 compliance for secure handling of method and data files.

The HIDEX 300 SL is clearly a sophisticated and versatile/many-faceted instrument. The software has many bells and whistles, however, the steady background coupled with the TDCR are what help this instrument stand out.
