MSL Solution Providers (MSL) is a microbiological testing laboratory, specialising in efficacy testing of biocides and disinfectant products used in a wide range of environments, including cleanroom disinfectant validation. In 2022, it was honoured with a prestigious Queen’s Award for Enterprise for International Trade, specifically for its outstanding short-term growth.
Founded in 2001, MSL is a complete service provider, offering an integrated regulatory and laboratory testing service. Its in-house accredited labs provide a comprehensive range of standard tests, including efficacy testing against bacteria, fungi, spores, viruses, mycobacteria, legionella, and algae. It also offers a tailored solution to specific testing needs, in order to support clients’ individual requirements.
Disinfectants are used in a wide variety of situations to reduce the number of microorganisms in the environment and on surfaces. All products need to be tested to prove they are effective against their claimed targets. MSL can assist with testing and regulatory services relating to disinfectant products.
Biocidal products will have been tested for efficacy against the standard EU test methods, however, cleanroom inspectors expect to see specific test data relating to the selected disinfectants used against the organisms isolated during routine environmental monitoring.
MSL can work with your environmental monitoring teams to check whether the disinfectants used are effective in each specific situation against the in-house environmental challenges and on each different surface type. This testing should be carried out routinely and specifically when changes to products or cleaning regimes are introduced.
The EN17272:2020 standard determines the disinfectant activity of processes used in the medical, veterinary, food, industrial, domestic, and institutional areas, using automated processes for distributing chemicals by air diffusion with no operator manually applying the disinfectant. This includes the disinfection of nonporous surfaces but not that of the air. In March 2021, MSL was the UK’s first leading commercial microbiological testing company to introduce this service in-house, performing tests in its new building, specially commissioned for this process.

The new BS 8628:2022 standard covers the requirements and methodology for testing the efficacy of UV devices. Largely based on the existing airborne disinfection standard EN 17272:2020, with some minor variations for UV devices, this method standardises a distance for the emitter from a test surface, allowing for an assessment of power vs contact time for the UV unit. It covers the requirements and methodology for testing the efficacy of UV devices, determining bactericidal, mycobactericidal, sporicidal, yeasticidal, fungicidal, virucidal and phagocidal activities.
MSL’s in-house laboratories have bespoke, purpose-built enclosures specifically set up to implement testing to this industry standard to assure companies that the UV disinfection system employed at their facilities is both suitable for use and effective against the organisms that pose the greatest risks.

MSL can perform any microbiological test methods (which include ISO, EU.ph. US.ph. JIS) and apply deviations appropriate to the intended use/application, to support disinfectant validation and BPR dossiers.
MSL can carry out site audits for cleaning validation, or provide the swabs, plates, and training for this to be carried out by cleanroom operatives themselves.
MSL provides not only a comprehensive range of standard tests, but also offers a tailored solution to your specific testing needs.
MSL customers are appointed with a dedicated technical project manager, who will be their one point of contact from the initial enquiry to the final report, and beyond.
MSL can provide support for all your biocide regulatory requirements.
