Specialist Microbiology Services

Microbiology is an intricate and complicated science. All too often, contract testing laboratories perform routine testing well but when a crisis arises or more in-depth work is required, they are unable to fully support their customers who are then left to seek out alternative service providers.

The Specialist Microbiology Team, based at our Rotherham site in South Yorkshire, is a dedicated team of technical experts able to provide ALS clients with a wide range of bespoke testing, trials, projects and requests as part of a genuine ‘One-stop shop’ solution.
