Beckman Coulter LS6500 Liquid Scintillation Counter, Ambient Temperature Range 15 – 35 °C, Beckman Coulter (CAT#: STEM-AIAEPO-0201-LGZ)

The Beckman LS-6500 system is equipped with a 32,678-channel analyzer, providing an effective resolution of 0.06 keV to obtain accurate results in a variety of samples. The patented H-Number Plus external quench monitor (H-Number Plus) is installed into the system to provide accurate decomposition per minute (DPM) calculations and automatic quench compensation. Both measurements are independent of sample volume or cocktail composition. This feature is also the basis for instrument calibration, color detection and correction, two-phase monitoring, unquenched window determination, and multi-label DPM quenching curves.

The LS 6500 counter lifts the sample plastic rack into the sample chamber instead of lowering the compartment into the sample chamber. This design prevents possible contamination of the chamber with dust or liquid residue. As for system operation, the combination of easy-to-use menus, context-sensitive help screens and 50 user programs make the LS 6500 a one-button system.

System Plus and System Advantage models are equipped with powerful analysis tools. Units come with a single or dual label DPM, a proprietary H-Number Plus quench monitor, and the Versa-Rack™ bottle system, allowing mixing of 20ml and 7ml vials. Enhancement packages and other features can be added later to meet emerging laboratory needs. The capacity of the instrument is 336 standard bottles (20ml), or 648 vials (7ml) or a combination thereof.
