The story
The company was founded by Jerry Cole and John Parmer in 1955 and took up shop in a 1,200-square-foot (110 m2) loft on West Illinois Street in downtown Chicago. In the 1960s, Cole-Parmer acquired Masterflex peristaltic pumps, followed shortly by the purchases of Gilmont Instruments and Manostat Pumps.
They were acquired by Fisher Scientific, now Thermo-Fisher Scientific, in 2001.
On July 17, 2014, Thermo Fisher Scientific Inc. agreed to sell one of its lab units, Cole-Parmer, to private-equity firm GTCR for $480 million in cash. The company has previously said its $13.6 billion acquisition of Life Technologies Corp. would allow it to cut costs while gaining from next-generation genetic-sequencing machines. It has also sought to expand in Asia-Pacific markets.
In 2025, Cole-Parmer was sold to Brookfield Asset Management Ltd.'s private equity group and Caisse de dépôt et placement du Québec for a reported 1.4 billion dollars (USD).
