About Tovatech
Meet Our Founders
Tovatech was founded by two Ph.D. chemists, Dr. Rachel Kohn and Dr. Robert Sandor. Their combined laboratory and business leadership experience continues to shape our practical, application-first approach to ultrasonic cleaning and laboratory equipment.
Founder
Dr. Rachel Kohn
Dr. Rachel Kohn has extensive experience in developing technology-based business opportunities. Prior to founding Tovatech, she successfully built international sales of novel analytical instrumentation for Smiths Detection as a Global Account Manager in the Life Sciences division. Dr. Kohn’s prior positions include Director of Business Development at Photon-X, a telecom component start-up, Project Manager at Cardinal Health, and Business Director at the Medical Device Concept Laboratory, a nonprofit research institution focused on development of biomaterials and implantable medical devices. In addition, Dr. Kohn held various positions at Hoechst Celanese Corporation, including Marketing Manager, Project Team Leader, Business Analyst, and Senior Research Scientist. She has authored 37 patents and publications based on laboratory research in diverse fields such as advanced drug delivery systems, polymer films and membranes, optical disks, and polysaccharides. Dr. Kohn has a B.A. in Chemistry from Barnard College and a Ph.D. in Organic Chemistry from M.I.T.
After working as a bench chemist for almost 20 years, Rachel knows lab equipment. She feels the pain of a technician operating with the wrong equipment and enjoys solving problems. “Ultrasonic cleaners and horn sonicators, precision balances from top loaders to microbalances, lab refrigerators and freezers were all common tools in my lab. I’ve had a very broad range of experience in several different fields of science and industry and that helps me understand the problems my customers are facing. Tell me about your challenges in research, development, quality control, manufacturing, or maintenance and I’ll do my best to help.”

Founder
Dr. Robert Sandor
Dr. Bob Sandor has over 25 years of experience managing high tech businesses. He has led the start up and growth of 5 technology companies. Dr. Sandor has marketed a broad range of technical products, including analytical instrumentation for pharmaceutical and semiconductor manufacturing, plastic sheet for construction and automotive applications, and general laboratory supplies. He has a track record of successfully commercializing leading-edge technology in the US market. As the VP/GM of Smiths Detection Life Sciences, he led the division in the commercialization of the paradigm-shifting IONSCAN LS. The IONSCAN LS is an in-house developed instrument for pharmaceutical QC analysis that achieved sales of $3MM USD in its third year of operation. As VP at ECI Technology, Dr. Sandor was responsible for marketing and global distribution of an analytical equipment product line serving the semiconductor industry. Dr. Sandor was also GM of Markson Labsales, a direct mail/catalog distributor of analytical laboratory equipment with annual sales of $3.5MM. He began his career at Hoechst Celanese Corporation, where he led the CRF-Cut Resistant Fibers business team and established the North American subsidiary of Hostaglas Plastic Sheet Products. Dr. Sandor has authored over 40 patents and technical publications. Dr. Sandor has a B.S. in Chemistry from The University of Rochester and a Ph.D. in Inorganic Chemistry from Brandeis University.
