About Streck
Established in 1971, Streck’s founder, Dr. Wayne Ryan, developed the company’s core technology of cell stabilization at a time when blood cells were still being counted manually using microscopes.
Streck researchers were able to facilitate automatic counting, leading to the development of an accurate system for calibrating platelet-counting devices. It was a profound breakthrough for hematology laboratories around the world – one that fueled their pursuit of innovative solutions for the clinical laboratory.
Today, innovation continues to drive their science. Streck holds over 40 patents on more than 20 products and makes testing and reagent materials for some of the industry’s leading instrument manufacturers.
