Perfectus Biomed are pleased to officially announce that the United Kingdom Accreditation Service (UKAS) have granted an Extension to Scope to our ISO 17025 schedule of accreditation for biofilm testing. The extension includes the Single Tube Method with Staphylococcus aureus and Pseudomonas aeruginosa.

What is an Extension to Scope (ETS)

A scope (or schedule) is the official document that outlines the activities for which the accredited body is granted accreditation. UKAS offer an extension to scope service for those who wish to add to/change their range of accredited activities. Changes to existing scopes is also possible, and can include:

  • Addition of new conformity assessment activities (tests, inspections, calibrations, areas of certification, etc.)
  • Addition of new locations (UK or overseas)
  • Expansion into a new area of accreditation

Extension to Scope for the Single Tube Method

Perfectus Biomed’s Method Validation Microbiologist, George Gray, lead the development and validation of the single tube method from the ASTM E2871 – 19 Standard. The method uses a CDC biofilm reactor to evaluate the efficacy of antimicrobial pesticides against two biofilm forming genus, Pseudomonas aeruginosa and Staphylococcus aureus. The method describes how to measure the efficacy of biocides against biofilm encased bacteria, using liquid or water-soluble powder formulations against bacterial biofilm.

Please contact us to understand how to perform the single tube method in line with Environmental Protection Agency (EPA) requirements in order to achieve a successful biofilm label claim. To find out more about the biofilm testing services we can offer, please visit our website.

The Perfectus Biomed management team would like to say a huge thank you to George and the team for their hard work and commitment to this project.
