Drug and alcohol testing company Randox Testing Services has moved into Hexagon Tower in Blackley, North Manchester.
Randox has taken a 6,500 sq ft laboratory as part of the company's plans to increase its global market share in providing forensic toxicology services.
Hexagon Tower was originally built in the 1970s and first occupied by Imperial Chemical Industries before being used by AstraZeneca and Avecia, prior to becoming a science park with its purchase by La Salle Investment Management in 2008.
The building is part of the national Business Environments for Science and Technology Network, the largest portfolio of privately owned science parks in the UK.
Gary McCutcheon, global manager at Randox Testing Services, said: "Manchester ranks second in terms of metropolitan economies within the UK, but when you factor in its geographical location, it really becomes an obvious choice.
"Outstanding air, road and rail infrastructure makes it an ideal hub location to service the UK market and further afield. Looking towards the future with Manchester's proud tradition of science and innovation, its universities offer a strong pool of quality graduates as we require expanding."
Chris Mitchell, associate director at owner LaSalle Investment Management, said: "Randox are exactly the right type of high-growth tenant suited for Hexagon Tower – innovative and ambitious.
"LaSalle's £2m investment in Hexagon Tower to date has modernised the facility into a high-quality, specialist environment with a vibrant and forward thinking community for pioneering businesses."
