Scintillation Counters

The Molecular Core has two Beckman Coulter LS6500 Scintillation Counters.

Purpose:
When working with radioactively labeled compounds, macromolecules or materials, one needs to assess how much radioactivity is present in the particular sample. A scintillation counter counts the amount of radioactive decay events from each particular radioactive isotope present in the sample.

Specific Description:
The LS6500 estimates counts per minute (cpm) in standard vials, miniature vials and Bio-Vials™. Vials are loaded into racks that can be stacked allowing multiple users to measure samples sequentially. Samples are placed in vials with a liquid or solid scintillator that converts radioactive decay events to photons which are captured by a photomultiplier. Auto DPM counting allows one to measure the radioactive isotopes 3H, 14C, 32P, 35S, 45Ca or 86Rb without quench curves.
