Dear Colleagues,

In October 1997, Beckman Instruments, Inc and Coulter Corporation became one company, to be known as Beckman Coulter. Combined, we will be able to better serve the market place through expanded product offerings and unparalleled support. Beckman Coulter's systems, consisting of instruments, chemistries, reagents, software and supplies, meet a variety of laboratory needs, from instruments used for pioneering medical research and drug discovery to diagnostic tools found in hospitals and physicians’ offices. The goal of Beckman Coulter, Inc. is to be a world leader in systems for diagnostics and bioresearch, providing you with solutions for INSIGHTometry: From Discovery to Diagnosis.

In 1948, the patent for the first cytometer was awarded to Wallace Coulter for the Coulter® Principle and the Coulter Counter® Model A. Today, fifty years later, we are pleased to have the opportunity to affirm our commitment to the sciences of Flow Cytometry and Immunology with this catalogue and its more than 1350 products, including 500 newly released products.
