Hidex 300 SL: An advanced, compact Liquid Scintillation Counter
01/09/2025
At a glance
> In this new video, Product Specialist Roy Corner talks through the key features and benefits of the Hidex 300 SL.
> Compact and front-loading, it is smaller than other Liquid Scintillation Counters, making it ideal for labs where space may be prohibitive.
> The counter has three PMTs for optimal counting geometry and TDCR counting, delivering higher efficiencies without using a standard source for calibration.
Half the size of other LSCs
The Hidex 300 SL is a compact Liquid Scintillation Counter with a footprint approximately half the size of other available models. It is front-loading, meaning it can be conveniently positioned underneath benches or in tight spaces, useful for existing or mobile laboratories where available space may be limited.
TDCR counting using three PMTs
The 300 SL uses three Photomultiplier Tubes (PMT) instead of two as conventional LSCs use. Each PMT is aligned at 120° from each other for optimal geometry, yielding better detection than conventional two-detector systems. This provides Triple-to-Double Coincidence Ratio (TDCR) counting.
But what is TDCR?
TDCR is an absolute counting method for obtaining counting efficiency of the samples without the use of external or internal radioactive sources. It delivers higher efficiencies and automatically calculates counting efficiency, which correlates to quenching. You can learn more about TDCR by watching our video here.
Dependable software
The 300 SL can be controlled by either Hidex’s MikroWin software or LabLogic’s Laura software running on an external computer. Other counters typically feature an internal computer physically built-in to the LSC itself. If these integrated computers fail, it renders the whole LSC inoperable, whereas the 300 SL’s operations are unaffected with software running on any computer. This also means software updates are regular, meaning users are using the latest versions.
