Oil Check Laboratory Services Limited (OCLS), a fluid analysis laboratory business based in South Yorkshire, has been acquired by a US group. Indiana-headquartered Polaris Laboratories’ acquisition of OCLS is set to support the company’s expansion into new markets and strengthen its global reach.
Headquartered in Doncaster, OCLS has developed a strong reputation for its lubricant and diesel fuel testing, in addition to its condition monitoring services. The company’s services support a diverse base of industrial and mobile equipment applications.
Indianapolis-headquartered Polaris Laboratories is an independent fluid analysis company that operates from seven laboratories worldwide. The acquisition is expected to support the group’s expansion into new markets, such as data centres, transformer oils and power generation, as well as enhancing its international presence and boosting its ability to serve customers in key global markets.
Post-acquisition, OCLS will continue to operate from its facility in Yorkshire, with Polaris Laboratories reassuring customers that they can expect service continuity. In addition, OCLS’s customers are set to benefit from enhanced scale, capabilities and investments in technology, supported by Polaris Laboratories and its partner, Riverspan Partners.
Bryan Debshaw, Chief Executive at Polaris Laboratories, commented: "Our focus is on scaling our capabilities in alignment with customer needs across the markets they serve.”
"OCLS has built a strong reputation in the UK, and this partnership expands our global footprint, strengthening our ability to deliver consistent, high-quality, and timely analysis to customers around the world."
Michael Volante, owner of Oil Check Laboratory Services Ltd, added: "We are proud of the business the OCLS team has built and the strong relationships we have with our customers.”
"Joining Polaris Laboratories allows us to continue operating with the same local expertise and customer focus, while gaining access to broader resources and global capabilities that will support our customers well into the future."
