Branford Castle Partners has added a fifth bolt-on to its life sciences instrumentation platform Lafayette Instrument with the acquisition of Sutter Instrument Corp., a provider of precision instruments for electrophysiology and neuroscience research.

Sutter, founded more than 50 years ago, supplies universities and research institutions globally.

Its product line supports cellular research, electrophysiology, and other life sciences applications.

Lafayette Instrument, acquired by Branford Castle’s Fund II in 2021, manufactures scientific instrumentation for life sciences, polygraph, and human evaluation.

The addition of Sutter brings electrophysiology capabilities to Lafayette's portfolio.

“Sutter’s strong product portfolio, deep technical expertise, and commitment to customer success make them a natural complement to Lafayette’s Life Science portfolio,” said CEO Benjamin Mangrich.

Ceon Francis, managing director at Branford Castle, noted that the acquisition broadens Lafayette’s product offering to better serve life sciences customers.

Advisors on the transaction included Akerman LLP as legal counsel and RSM as accounting/tax advisor to Branford Castle.

EC M&A acted as financial advisor and Donahue Fitzgerald LLP as legal advisor to Sutter.

Financing was provided through senior debt from Byline Bank and mezzanine debt from Brookside Capital Partners.

The deal closed following the announcement.
