The most advanced, transportable and user-friendly Liquid Scintillation Counter (LSC) on the market
The Hidex 300 SL liquid scintillation counter 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.
Hidex’s MikroWin software version 5.62 is fully compatible with Windows 11
Hidex is the only manufacturer of liquid scintillation counters whose software is fully compatible with Windows 11, Microsoft’s latest major release. Hidex’s MikroWin version 5.62 can be run on any external desktop, whereas other manufacturers use internal computers that are integrated into the liquid scintillation counter itself.
This can present problems if there is a fault with the internal computer, as it prevents the user from operating the instrument as well. Being able to use an external desktop to manage your instruments allows MikroWin software to be easily updated with new releases and is compatible with Microsoft’s latest security features introduced in Windows 11.
NEW: Chevron has successfully developed new radiocarbon analysis methods based on TDCR liquid scintillation counting, click here to read more.
Super Low-Level 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 utilizes 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 minimizes the weight of the liquid scintillation counter.
Reduces cosmic radiation.
Eliminates X-rays from lead shield.
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 on the liquid scintillation counter.
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.

Easy to use liquid scintillation analyzer software
The 300 SL liquid scintillation counter uses an external PC which is Windows 7, 8 and 10 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.
Do I need a dedicated cart/table?
No, the 300SL is a benchtop instrument. A table can be purchased if desired.
Is the 300SL liquid scintillation counter portable?
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).
How do I collect and analyze my data?
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.
Is the liquid scintillation counter networkable?
Since you use an external PC it can be networked. The instrument can generate an Excel file and send it to the network automatically.
When do I need the internal radiation source?
The internal source is only needed if you are measuring dual-labeled samples with variable quench.
Do I need the Temperature Control module?
Temperature control is only recommended if you are using long count times and do not have a stable air conditioned laboratory.
What is the capacity of the 300SL?
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 organizer feature it is possible to run several assays on the same tray and have the results exported separately.
