Follow on Google News | Versatile pH Meter Used in the Cleanest Room in the WorldA METTLER TOLEDO SevenMulti pH Meter has recently been installed at the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) in Stuttgart, Germany.
By: ePublicRelations The Fraunhofer-Gesellschaft is one of the leading organizations for applied research in Europe. It undertakes application- The institute focuses on areas such as corporate logistics, automation and robotics as well as surface technology. Materials and equipment tested by the Fraunhofer IPA are awarded the “Fraunhofer IPA TESTED DEVICE” certificate. This certifies the clean room capability for the different classes of equipment. Different physical and microbiological tests are performed in order to be able to provide exact information about each tested object or material and award the certificate. Our contact at the Fraunhofer IPA is Markus Keller of the Ultraclean Technology and Micro-Manufacturing Department. The Super Cleanroom The Ultraclean Technology and Micro-Manufacturing Department deals with technical questions concerning miniaturized production processes where contamination is a critical issue. These are encountered in branches such as the semiconductor industry, the automotive field and the life sciences. The showpiece in this department is the “cleanest” Cleanability of surfaces All surfaces used in hygienic production environments must according to the European Hygienic Engineering & Design Group (EHEDG) be especially easy to clean and disinfect. Polished stainless steel surfaces are considered ideal. To measure the effectiveness of the cleaning process, the microbiological bacteria count of the surfaces is measured before and after the cleaning using a surface contact method (Figures 1 and 2). This is performed by pressing a petri dish coated with nutrient agar against the surface with a defined force for 5 seconds. In this test method, the SevenMulti and the InLab Routine Pro pH electrode are used to prepare and set the exact pH of the nutrient agar. Metabolization of materials Under certain climatic and environmental conditions, microorganisms can colonize and propagate on the surfaces of plastics. Their presence can not only damage the plastic but also influence the proper functioning of the components that contain the plastics. To assess the action of microorganisms on materials, the Fraunhofer IPA uses the European EN ISO 846 test standard. The microbiological action on the plastic samples is investigated in a carbon-free nutrient medium. If no growth occurs in the culture medium, then the sample does not contain any nutrients for growth and metabolism can be excluded. The SevenMulti S47 two-channel instrument is used to set the pH of the mineral salt stock solution using a sterile 0.01 mol/L NaOH solution. # # # METTLER TOLEDO specializes in the area of precision instruments for professional use. METTLER TOLEDO laboratory instruments are used in research, scientific, drug discovery, and quality control labs, amongst many others in the pharmaceutical, chemical, food and cosmetics industries.
