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…

Beckman introduced the LS-16 system in 1969.

Scintillation counters detect ionizing radiation by counting the light flashes produced by the particles as they pass through certain solids or liquids.

Arnold Beckman invented his first pH meter in 1934 at the request of a chemist from the California citrus industry, who needed an accurate way to measure the acidity of his product. The resulting instrument kicked off…

Beckman's Biogamma II was introduced in 1975. Radioimmunoassay (RIA) is a technique for measuring the antigen concentration. Known quantities of radioactive (labeled or “hot”) antigens and antibodies are mixed, then…

High performance liquid chromatography analyzes the components of a sample by pumping a solution through a column containing an adsorbent material, which separates and interacts distinctly with the components. The flow…

The Expandomatic SS-2 was designed for the detection of very small changes in pH and use in potentiometric and polarization titrations.
