Pharmaceutical Bioburden Testing

Pharmaceutical Bioburden Testing

Bioburden testing is an important part of the pharmaceutical manufacturing process as it helps to identify and quantify the presence of microorganisms in the product, raw materials, or manufacturing environment. At our pharmaceutical bioanalytical laboratory, we offer comprehensive bioburden testing services to ensure the quality and safety of your pharmaceutical products. We utilize state-of-the-art testing methods and a team of experienced microbiologists to deliver reliable and actionable results.

Our bioburden testing methodology

Our bioburden testing services are conducted in accordance with the following industry-standard reference guidelines:

  • ISO 11737-1 - Sterilization of medical devices - Microbiological methods - Part 1 - Determination of a population of microorganisms on products.
  • USP <61> - Microbiological Examination of Nonsterile Products - Microbial Enumeration Tests.
  • USP <62> - Microbiological Examination of Nonsterile Products - Tests for Specified Microorganisms.
  • EP 2.6.12 - Microbiological Examination of Non-Sterile Products - Microbial Enumeration Tests.
  • EP 2.6.13 - Microbiological Examination of Non-Sterile Products - Test for Specified Microorganisms.
  • JP 4.05 - Microbial Limit Test.

Our laboratory utilizes the most advanced equipment and techniques to ensure accurate and reliable results, including:

  • Automated colony counters.
  • Incubators with precise temperature and humidity control.
  • Laminar flow cabinets for sterile sampling and handling.
  • Automated liquid handling systems.
  • Real-time PCR instruments for rapid microbial identification.
