About IMSL

IMSL is a testing and consultancy service specialising in the microbiology of materials, industrial processes and products. It is a private limited company that was formed in October 1996 and is located in purpose-built laboratories and offices 50 km west of London, near Fleet in Hampshire, UK. IMSL has a diverse customer base from throughout the UK, mainland Europe, the Middle East, USA and the Far East.

As the name implies, IMSL specialises in industrial applications mainly in the fields of product and production hygiene, preservation technology, treated articles and disinfection testing. IMSL is experienced in the generation of data for regulatory approval of active substances and biocidal products under a number of schemes, especially the EU BPR. IMSL also has extensive experience in the analysis of a wide range of finished materials for both their susceptibility and resistance to microbial deterioration (e.g. activity of fungicides and algicides in paint films, determination of the efficacy of materials intended to limit the growth of bacteria on their surface / within their matrix etc) as well as disinfectants (both in suspension and on hard surfaces). In contrast to most microbiology-based companies, no standard food and water testing is undertaken.

IMSL is actively involved in the development of standardised test protocols both through internal developments and involvement with the International Biodeterioration Research Group (IBRG). In the latter instance, IMSL is the lead laboratory in the development of standardised methods for the assessment of the performance of biocides in cooling water etc, the determination of the antibacterial activity on the surface of polymeric materials (in collaboration with the SIAA in Japan) and textiles (including the control of odour). These activities are all progressed through the use of international collaborative ring tests and meetings (IMSL has hosted 3 such meetings in the past 25 years). IMSL also makes regular presentations at international scientific and technical meetings, contributes to the technical literature in relevant areas and is involved in the drafting of regulatory guidance.
