Shop CRMs

Produced in accordance with ISO 17034 requirements and certified through ISO 17025 accredited laboratory testing, our reference standards are intended for use globally by antimicrobial test laboratories.

Our Certified Reference Materials are innovative test standards developed from years of antimicrobial testing expertise in the global market.

Each unit consists of a sample set of both Positive (orange) and Negative (white) Test Controls, which are intended to guarantee the highest quality of antimicrobial method performance available and to verify proper ISO 17025 test performance.

Situ Biosciences’ Certified Reference Materials have been designed to provide confidence in test results through the following applications:

  • Guarantee the highest quality of antimicrobial method performance available
  • Verify proper ISO 17025 test performance
  • Evaluate product performance by acting as a direct comparison (with the possibility of establishing long term control charts)
  • Create high quality in-house test controls for a variety of antimicrobial methods

Moreover, our reference standards can be utilized in variety of laboratory practices. They are intended to streamline the validation of internal laboratory procedures, aide in proficiency testing and employee training, and help meet performance requirements.

Certified Reference Materials are required to be used under certain conditions for ISO 17025 compliance. Our goal is that the inclusion of our Certified Test Controls in Antimicrobial Methods will raise the quality of laboratory testing, and therefore product performance, throughout the industry.
