Electroencephalographs are used to monitor and record electrical activity of the brain.

Based on the Coulter principle, the Beckman Particle Counter quantifies and sizes particles suspended in a fluid, like blood cells, bacteria, and a wide variety of other substances. The instrument works by drawing…

This image shows the graphical print-out of the instrument's readings. A respiratory recorder records both oxygen and carbon dioxide levels during respiration.

First marketed in 1960, the Beckman/Spinco Model 120 Amino Acid Analyzer used the Spackman-Stein-Moore technique of amino acid chromatography.

Spirometers determine lung capacity and health by measuring how quickly respiration happens and how much air is both inhaled and exhaled.

Used to generate and pump gradients in combination with centrifuges and ultracentrifuges.

Beckman Instruments began producing centrifuges after their January 1, 1955 acquisition of industry leader, Specialized Instruments Corporation, or Spinco. With Spinco came the famous Model E Ultracentrifuge, which was…

Spirometers determine lung capacity and health by measuring how quickly and how much air is inhaled and then exhaled.

The instrument includes heart rate and echocardiogram monitoring.

First marketed in 1960, the Beckman/Spinco Model 120 Amino Acid Analyzer allowed users to quickly perform amino acid chromatography. This unidentified model is likely a contemporary of the 120.

The unit in the photograph includes a Beckman OM-11 oxygen meter, LB-2 gas analyzer, and R411 dynograph recorder.

This instrument was designed to be incorporated into electroencephalograph units and included an impedance meter. An electroencephalogram test detects electrical impulses in the brain via electrodes attached to the…
