About Us

Russell Mainstream Supply Limited has been a trusted name in hospital and laboratory hygiene, as well as water treatment solutions, for nearly two decades. Now in our 19th year of business, we’ve grown steadily year after year, proudly supplying a wide range of high-quality products to customers around the world. Our commitment to competitive pricing, fast and reliable delivery, and exceptional after-sales support has earned us a loyal global customer base.

The Russell name has a long-standing reputation in the industry. The story began in the early 1970s when the late John Russell founded Russell pH, a pioneering manufacturer of electrochemical sensors. The company became one of the world’s largest independent sensor manufacturers before being acquired by the Orion group in the 1990s—now part of a major global corporation.

Following the sale of Russell pH, we launched Russell Mainstream Supply Limited, expanding our product range and reaching into new industries. Today, we continue that legacy with a strong focus on innovation and customer experience.
