Frequently Asked Questions

Sartorius has implemented a robust quality management system that includes batch testing and validation for every production run. Our quality control processes involve physical, chemical, and microbiological testing to ensure that every batch meets the highest standards for consistency and reliability. We also conduct regular audits and process improvements to maintain the highest level of product quality.

Absolutely. We provide comprehensive documentation for all our products, including certificates of analysis, compliance with ISO standards, and adherence to relevant regulations such as USP and EP for pharmaceutical applications. Download Certificates & Technical documentation.

Sartorius microbiology membranes come in a variety of pore sizes, including 0.45 µm which the most represented in regulations like ISO 7704 for microorganism retention as it offers the optimal compromise between microbial retention and permeability with the nutrient media. In some applications, a pore size of 0.65-0.8 µm is sufficient to retain larger cells of yeasts and molds.

Sterility testing methods should be validated initially and then revalidated on a regular basis, or whenever significant changes are made to the test method or product, to ensure ongoing reliability and compliance with regulatory standards.

Industrial microbiology is performed in a variety of activities across multiple industries, including but not limited to:

  • Pharmaceutical Manufacturing: To ensure that drugs and vaccines are free from microbial contamination
  • Food and Beverage Production: To detect spoilage organisms and pathogens to ensure food safety
  • Cosmetics Industry: To ensure that cosmetic products are safe for use and free from harmful microorganisms
  • Water Treatment Facilities: To test drinking water and wastewater for microbial contaminants
  • Environmental Monitoring: To assess the presence of microorganisms in various environments, such as soil, air, and water (recreational, tap, swimming) to protect public health
  • Agriculture: To test for soil health, plant pathogens, and ensure the safety of agricultural products
  • Biotechnology Research: To monitor cell cultures and other biological materials for contamination
  • Quality Control Laboratories: To validate the sterility and microbial limits of various products and environments
  • Healthcare Facilities: To monitor the cleanliness and infection control measures in hospitals and clinics
  • Microelectronics: To prevent surface contamination from ultrapure water, potentially altering adhesion properties or electrical characteristic


The primary method is membrane filtration, which involves filtering the beverage through a membrane to capture microorganisms for subsequent incubation and counting. Key equipment includes a filtration apparatus, a vacuum source, sterile membranes, and culture media for growing captured organisms.

They save time and minimize the risk of secondary contamination by providing pre-sterilized components that are ready for immediate use without additional preparation.

Nutrient pad sets offer a stable shelf-life of two years without the need for refrigeration, and they can be activated simply by adding sterilized water, which improves efficiency and reduces storage requirements.

Single-use filtration units save time by eliminating the need for flaming and sterilizing equipment, reducing preparation time by up to 43% compared to reusable stainless steel funnels.

Critical factors and practices that inhibit microbial growth include maintaining proper hygiene in the winery, controlling the temperature and pH of the wine, using preservatives like sulfur dioxide, and ensuring adequate alcohol content. Regular microbiological testing at critical control points is also essential to monitor and prevent microbial instability.
