Majority owner Joseph Platano will retire as chairman of the company, while Doug Evans will continue as president after the takeover by Union Park Capital.
Unity Scientific was formed from the merger of Unity Scientific and Westco Scientific Instruments.
Unity Scientific is a manufacturer of near infrared (NIR) analyzers and its instruments are used for quality control determination in markets such as food, dairy, chemical and pharmaceuticals.
Morgan Jones, managing partner of Union Park and chairman of the board, said it focuses on instrumentation businesses serving the needs of industry.
“Unity delivers the personal service to its customers that only a smaller company can, but marries that with the punching-power in its technology innovation to define world class performance.”
Union Park Capital is a private equity investment firm that focusses on long-term acquisition and growth strategies for scientific instrument companies.
Doug Evans, president of Unity Scientific, said the brand remains unchanged.
“We have a great technical and manufacturing team for new and market-leading products, the most experienced field technical support and service team in our industry, and a concerned and dedicated sales staff.
“With new investment and renewed energy, we will be able to take the next generation of advanced and high quality products to the market to make our customers extremely satisfied with our products and services.”
