The pictured dials are part of a Beckman DPM-100 Liquid Scintillation System. This photograph was incorporated into a composite image featuring a Helipot potentiometer.

Liquid scintillation counters measure the radioactivity of a sample by mixing the sample with a solvent containing a scintillator, which will emit photons in the presence of radioactive materials. The counter measures…

Beckman introduced the LS-16 system in 1969.

The Beckman Beta-Mate II (styled β-Mate II) was a single-sample, single-channel, manual counter. The Beta-Mate I was first offered in 1970, so this model was likely produced soon after.

Note the plate on the door, modified by hand to read LS-100; the original DPM-100 remains visible. The original photograph depicts the mid-1960s instrument, probably modified in the early 1970s to represent the LS…
