The Tri-Carb 5110TR liquid scintillation counter is a fully loaded premium instrument capable of more accurately detecting Ultra Low Level counts in mixed and unknown samples using proprietary Dual Phase Separation and PSA Histogram technology.

Standard features
  • TR-LSC (Time-resolved Liquid Scintillation Counting) for high sensitivity, low background liquid scintillation counting
  • QuantaSmart Software a robust multitasking, easy networking environment with unlimited assays in a secure multiuser environment
  • Alpha Beta Separation uses Dual PSA Discriminator and PSA Histogram to improve accuracy for mixed and unknown samples
  • ULLCM (Ultra Low Level Count Mode) with Pulse Amplitude Comparison (PAC) decreases the component of background produced by optical crosstalk, increasing system sensitivity (E2/B) to a factory test minimum of 500 for 3H and 1,400 for 14C
  • SpectraWorks 2 spectral analysis package that determines optimal counting regions, and calculates figure of merit automatically
  • Enhanced IPA (Instrument Performance Assessment) monitors performance metrics for the life of the instrument
  • Replay reanalyzes sample counts without recounting samples
  • Dynamic color correction ensures accuracy of tracking lower energy sample spectra over a wide quench range
  • Auxiliary Spectrum Memory stores rejected events for future analysis
  • Bi-directional sample conveyer with a capacity of up to 408 (20mL vials) or 720 (4 or 7 mL vials)
  • Varisette
    sample cassette for intermixing vial sizes without special adapters
  • Operational-status LED indicator for clear assay status updates at a glance
  • Luminescence Correction adjusts for chemiluminescence interference
  • Direct DPM determines single-label DPM in any cocktail without the use of quench standards
  • 60 Quick Count protocol flags with the flexibility to define unlimited assays
  • Fold-away ergonomic arm adaptable to enter data either sitting or standing
  • Built in Computer with Windows 10 Operating System
