Core service details
Bioburden, sterility, surface swab, stability, laundry, and dishwashing liquid testing.
Bioburden testing is used to check the microbial load in a product, and this test helps monitor microbial presence in raw materials, finished products, or during the manufacturing process. Testing is conducted according to USP 61 and ISO 11737-1:2006.
Sterility testing aims at medical devices labelled as sterile by manufacturers. It checks microbial presence in the product and supports product safety. Sterility testing follows procedures based on USP 71 or ISO 11737-2:1998.
RWL conducts surface swab testing on porous and non-porous surfaces, as well as air monitoring. Surface swabs help check cleaning effectiveness, disinfection procedures, bacterial count levels, and hygiene in facilities, products, and public environments.
Consultancy is the core part of Real World Labs. RWL supports antimicrobial product development, efficient antimicrobial agent screening, regulatory-aligned testing, and field trial design.
RWL can support bespoke dishwashing liquid testing, dishwasher sanitization testing, laundry product testing, antimicrobial textile testing, and stability testing by modifying test methods and conditions around manufacturer and customer requirements.
