Exxelia Ohmcraft Custom Resistors Enable Metabolic Analyses of Live Cell Cultures in Pharmaceutical Research

ROCHESTER, N.Y., April 9, 2020 — In the development of new pharmaceutical therapies, researchers conduct metabolic analyses of live cell cultures to understand the critical role of metabolism in a wide variety of diseases and conditions.


To do so, they must rely on life science research and diagnostic instruments with complex high gain amplifier circuits. Leading manufacturers of this type of equipment have partnered with Exxelia Ohmcraft to design custom, high-resistance surface mount resistors that are essential to the function of these circuits.

Specifically, oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) are two key indicators of mitochondrial respiration and glycolysis that provide a systems-level view of cellular metabolic function in cultured cells. The analyzer equipment conducts these measurements automatically.

“The accuracy and reliability of these tools are crucial to the researchers’ ability to make progress in their studies, which have the potential to change—and save—lives,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “To meet the design needs of this particular application, we developed a custom resistor solution with a unique form factor and used special terminations to facilitate the manufacturability of the end product.”

Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

50th anniversary of our Pessac manufacturing site

Our manufacturing site in Pessac is one of the 12 industrial sites of Exxelia. It has approximately 130 employees. “We produce essential but inexpensive parts, but we produce 50 million a year! And we have a year of visibility on our order books", "We produce parts in complex alloys here, but also our own recipes for insulating ceramics", assures Mickaël Pelé, Director of the Exxelia Pessac factory. This factory was founded in Pessac half a century ago: it is an integral part of the life of the City and the Region, which have actively participated in its development. Perfectly inserted into the local ecosystem, there are numerous interactions with neighboring institutions, laboratories, universities, schools and businesses. The Pessac factory was built in 1971 and inaugurated in September 1972. Its creation was initiated by Jean-Claude Asscher, President of the Tekelec-Airtronic group. Initially dedicated to distribution, the Tekelec-Airtronic group launched into manufacturing under license to then develop and industrialize its own products. Its development followed that of electronics, telecommunications and IT in France and around the world. The group will reach a significant size: in 1992, with 20 companies employing 3,000 people in different countries, its turnover will exceed one billion dollars. The Pessac plant remained associated with the group until the early 2000s.   Here is a retrospective of the event in video:
