This accessory for Beckman's line of infrared spectrophotometers is designed to remove all moisture from the air passing through the spectrophotometer, which otherwise could interfere with its readings.

Colorimeters are used to quantify the concentration of a solute in a solution by measuring the absorbance of a particular wavelength or color of light by the solution.

Two of the men greeting Arnold and Mabel Beckman are identified as Russ Simpson and Robert Tily.

The result of joint research and development undertaken by Beckman Instruments and six sugar industry laboratories, this instrument was designed to quantitatively measure the whiteness of sugar.

Used to detect gas leaks in other systems and instruments.

Pycnometers are used for making density/volume measurements of solids using gas displacement. The Model 930 was marketed as early as 1961.

Beckman Instruments entered the gas chromatograph business in 1956 with the acquisition of the successful Watts Manufacturing Company. Later that year, Beckman Instruments produced its first gas chromatograph, the GC-1,…
