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.

Exclusive 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

Additional Standard Features:

  • 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

Physical data

  • Dimensions H/W/D 18.5/40.5/44 in (47/103/112 cm)
  • Weight 523 lb (238 kg)
  • Electrical requirements 100-240 Vac 50/60 HZ 3-prong grounded plug

Typical performance data

  • Energy range: 0-2,000 keV
  • Efficiency, Normal Count Mode (minimum acceptable):
    3H (0-18.6 keV): 63%
    14C (0-156 keV): 95%
  • Observed Background, Normal Count Mode (average):
    3H (0-18.6 keV): 17 CPM
    14C (0-156 keV): 26 CPM
  • Figure of Merit (E2/B), Normal Count mode:
    3H (0-18.6 keV): 180
    14C (0-156 keV): 360
  • Figure of Merit (E2/B), Ultra Low Level Count Mode (ULLCM):
    3H (0-18.6 keV): 500
    14C (0-156 keV): 940

Note: The efficiencies, backgrounds, and E2/B values for the Normal Count Mode were determined using PerkinElmer sealed large vial glass standards set P.N. 6008500 verified with NIST standard activity.

Complete Solutions for NASH Research

When Non-alcoholic fatty liver disease (NAFLD) progresses to nonalcoholic steatohepatitis (NASH), with inflammation and damage to liver cells it can cause fibrosis, cirrhosis and liver failure or cancer. Despite the prevalence of NAFLD and NASH rising, their remains no approved treatments. But studies show that fat and scar tissue can leave the liver, suggesting that they are reversible.

This brochure guides you through complete solutions to support your NASH research efforts.

Totally RAD Infographic Flyer

Radiometric detection (RAD) is one of the most proven techniques for molecular quantitation around – and it’s still indispensable for key applications. Here’s the state of the industry, and where it’s headed.

Overview Guide: Know all about Radioactivity Analysis in Drinking Water as per regulatory guidelines

European council's new directives on gross a/ß-measurement in drinking water have been the focus of many laboratories throughout Europe and another part of the worlds. The change in requirements such as sampling rate, detection limits, and more which have forced many labs to upgrade instrumentation and adjust their previous methods. This guide has been developed to do just that and provides a fast, gross a/ß–screening method as a reference for those looking to establish a new method. Should you find yourself needing additional support, PerkinElmer can also provide online or on-site training to help you set up new methods on PerkinElmer liquid scintillation counters.
