Sigma-Aldrich Signs Supply Pact for Reference Materials
By

Sigma-Aldrich Corporation has signed an agreement with Public Health England (PHE) to manufacture and supply bacterial and fungal NCTC/NCPF certified reference materials (CRM) in Lenticule disc format worldwide for use as controls in food, water, environmental and clinical testing microbiology laboratories.

Each CRM Lenticule disc consists of a stipulated level of a pure culture of viable bacteria or fungi in a control-dried water-soluble matrix. The bacterial and fungal strains are prepared directly from strains selected from PHE’s National Collection of Type Cultures (NCTC) and National Collection of Pathogenic Fungi (NCPF).

The CRMs will be produced in accordance with ISO Guide 34 and individually packed at Sigma-Aldrich for customer convenience. The company has invested in a new, dedicated Biosafety Level 2 facility and expanded the scope of our ISO 17025/ ISO Guide 34 accreditation to manufacture this product range.
