What is Environmental Lab Testing?

Environmental microbiology testing and monitoring ensures the safety and quality of medical devices and products by assessing microbial contamination levels in manufacturing environments and packaging. By employing methods compliant with ISO 18593 and CLAS scope, our environmental lab provides comprehensive testing services, including swab tests for bacteria, yeasts, and moulds, as well as specific microorganisms like Enterobacteriaceae, Coliforms/E coli, Pseudomonas spp, and Staphylococcus aureus.

Manufacturing under hygienic conditions is essential to avoid microbiological problems and ensure that products consistently meet required quality standards. We offer the following testing to support routine plant hygiene monitoring and the investigation of microbiological issues. Our in-house environmental lab testing methods based on ISO 18593 covered by our CLAS scope.
