The laboratory

Studio Ambiente S.r.l. has acquired over the years experience and technical expertise in the execution of microbiological and physical analysis on medical products and devices as well as cosmetics and biocides. The analytical offer is able to support companies also for the execution of chemical analysis and biocompatibility test, through the collaboration with qualified external laboratories, identifying the appropriate analysis to fulfill regulatory and mandatory requirements of the pharmacopoeia, standards, guidelines, directives and applicable laws.

All tests are carried out according to protocols regulated in European Standards of reference or official guidelines and recognized at European and international level (EU Pharmacopoeia, ISO standards, FDA guidelines …). The laboratory employs qualified technical personnel able to satisfy specific and dedicated requests such as the development of new methods or the development of experimental tests.

The company is in an area of about 500 square meters inside a commercial use building.

In the area dedicated to the offices are located the consulting activities, a sales office, a technical secretariat where the activities of acceptance of samples are carried out, a meeting room and management office. The laboratory area is divided into a warehouse area, a reagent preparation and storage area, an analytical area dedicated to non-sterile processes and an analytical area for sterile processes, an ISO 7 class clean room with an ISO 5 laminar flow cabinet. In the analytical area there are class A (ISO 5) microbiological 5 laminar flow cabinet, climatic rooms for ICH stability studies, incubators dedicated to microbiological analysis and thermostats for accelerated ageing for shelf-life studies, steam autoclaves for soil preparation, electronic dynamometer with motorised stand dedicated to packaging tests and further advanced technical equipment.
