Hidex 300 SL

Liquid Scintillation Counter

Similar to the standard instrument the Hidex 300 SL super low-level liquid 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 turned off for high energy samples and does not interfere with alpha/beta separation.

The 300 SL liquid scintillation counter utilises a unique design with three photomultiplier detectors which are aligned 120 degrees from each other to offer 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 liquid scintillation 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.

Optimal Lead Shield Design
A minimum of 70 mm lead in all directions provides excellent shielding and minimises the weight of the liquid scintillation counter.

Lead Shutter
Reduces cosmic radiation.

Copper Shielding
Eliminates X-rays from lead shield.

Measurement Chamber
Highly reflective proprietary paint maximises photon detection.

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

PMTs
Three PMTs detectors in coincidence mode provide optimal counting geometry and facilitate TDCR calculations on the liquid scintillation counter.

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.

No, the 300SL is a benchtop instrument. A table can be purchased if desired.

Since it does not contain an internal radiation source there are no regulatory restrictions in transporting it.

Due to its small size the 300SL can easily be transported between labs and also placed in mobile labs/vans and research vessels (r/v).

The 300SL liquid scintillation counter is capable of several calculations to allow you to process your data, which can then all be exported automatically to excel or to a text file compatible to your current LIMS system.

Since you use an external PC it can be networked. The instrument can generate an Excel file and send it to the network automatically.

The internal source is only needed if you are measuring dual-labeled samples with variable quench.

Temperature control is only recommended if you are using long count times and do not have a stable air conditioned laboratory. 

The 300SL can take up to 96 x 7ml vials or 40 x20ml vials per tray and takes one tray at a time. Using the organiser feature it is possible to run several assays on the same tray and have the results exported separately.
