Perkin Elmer MicroBeta 2 microplate scintillation counter 

$ Why not call your sales representative today about pricing and availability

The MicroBeta® is the latest version of the number one microplate liquid scintillation MicroBeta® (Trilux) line from PE.

The MicroBeta adds new and improved capabilities for researchers engaged in all major radiochemical and luminescence applications. By combining LSC functionality with plate reader simplicity, it enables vast savings in time, consumables and waste for your LSC screening applications.

MicroBeta2 is ideal for assays using 3H, 14C, 32P, 33P, 35S, 51Cr, 125I and glow-type luminescence labels as well as other scintillation proximity assays. It counts filters and tubes in addition to microtitration plates – micorplates.

  • 1, 2, 6 or 12 detectors  (subject to availability)
  • Counting modes include single and dual label CPM, single and dual label DPM, and luminescence counting.
  • PE has patented Time-Resolved Liquid Scintillation Counting - (TR-LSC) mode to improve counting capabilities significantly with opaque plates and low energy isotopes. TR-LSC mode can generate close to dual-PMT co-incidence counting performance by using top PMTs only.
  • Unique detector design consists of two photomultiplier tubes (PMT). One is located below the sample, the other above the sample. These count the sample simultaneously, in coincidence, which allows the best possible counting geometry, superior counting efficiency and the most efficient reduction of background.
  • PMT positioning for the measurement is automatic. Maximum height of the sample for 16- and 32-shelf MicroBeta2 is 45 mm and for the instrument having robotic loading shelf it is 20 mm.
  • A really slick cassette sample changing mechanism provides a flexible system for varying sample types. Microtiter plates, micro-centrifuge tubes, 4 mL liquid scintillation counting (LSC) vials and PE proprietary Filtermats can be loaded simultaneously into the instrument.
  • Standard bar code reader allows recognition of 100 protocols and other counting commands. An optional microplate bar code reader can read the front as well as right-hand side of a plate.


Three counting windows allow the analysis of the signal in three independent counting regions. Background subtraction enables fixed samples or values obtained from detector normalization to be used for calculations. Half-time correction is a correction facility for CPM and DPM values. The zero time may be the start time of the assay or a specified date and time. Freely selectable data output options include sample/plate ID, quench parameters (SQP(I)), spectrum plot, date and time, CPM and DPM monitors and statistical analyses. Output data format can be customized to either plate or list format. Instrument Performance Assessment (IPA) allows the user to monitor the performance of the instrument with the standard samples. The user may store the data for later analyses.
