Wallace H. Coulter (February 17, 1913 – August 7, 1998) was an American electrical engineer, inventor, and businessman. The best known of his 85 patents is the Coulter principle , which provides a method for counting and sizing microscopic particles suspended in fluid.
A Coulter counter [1] [2] is an apparatus for counting and sizing particles suspended in electrolytes. The Coulter counter is the commercial term for the technique known as resistive pulse sensing or electrical zone sensing. The apparatus is based on the Coulter principle named after its inventor, Wallace H. Coulter.
Joseph and Wallace Coulter circumnavigates these difficulties by inventing the principle of using electrical impedance to count and size microscopic particles suspended in a fluid. [5] [13] This principle is today known as the Coulter principle and was used in the automated blood cell counter released by Coulter Electronics in 1954.
The first impedance-based flow cytometry device, using the Coulter principle, was disclosed in U.S. Patent 2,656,508, issued in 1953, to Wallace H. Coulter. Mack Fulwyler was the inventor of the forerunner to today's flow cytometers – particularly the cell sorter. [6] Fulwyler developed this in 1965 with his publication in Science. [7]
An AI-powered death clock is getting an influx of use after claiming to predict the method and age at which you will die. Death Clock says it utilizes AI to analyze age, weight, sex, smoking and ...
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
George Clooney had some pointed remarks about the Donald Trump administration, describing the current political climate as one where people “don’t worry about facts.” “You take a narrative ...
A 3-part differential cell counter uses Coulter's principle to find the size and volume of the cell. The sample is lysed and dissolved into an electrolyte solution in a container, which also holds a smaller container. The smaller container has two pumps running to and from its solution, one creating a vacuum and the other replacing the lost ...
