Beckman Coulter LS6500 Liquid Scintillation Counter, Beckman Coulter (CAT#: STEM-CTEPO-0120-YJL)

Beckman Coulter LS6500 Liquid Scintillation Counter, model LS6500, is manufactured by Beckman Coulter. The Beckman LS-6500 systems is equipped with a 32,678 channel analyzer that delivers an effective resolution of 0.06 keV for accurate results across a variety of samples. A patented H-Number Plus external quench monitor (H-Number Plus) fitted into the system provides accurate disintegrations per minute (DPM) calculations and Automatic Quench Compensation. Both measurements are independent of sample volume or cocktail composition. The feature is also the basis for instrument calibration, color detection and correction, two-phase monitoring, unquenched window determination and multi-label DPM quench curves.
Instead of lowering the compartment to the sample chamber, the LS 6500 counter raises the sample plastic racks to the sample chamber. This design prevents possible contamination of the chamber with dust or liquid residue. As for system operations, the combination of easy-to-use menus, context-sensitive help screens and 50 user programs makes the LS 6500 a one-button system.
The System Plus and System Advantage models are equipped with powerful analysis tools. Units come with a single or dual label DPM, an exclusive H-Number Plus quench monitor as well as the Versa-Rack™ vial system which allows mixing of 20 mL and 7 mL vials. Enhancement packs and other features can be added later to address emerging laboratory needs. Instrument has capacity for 336 standard vials (20 mL), or 648 mini-vials (7 mL) or combination thereof.
