About Phywe

Founded in Göttingen, Germany in 1913 by Dr. Gotthelf Leimbach, Phywe Systeme GmbH & Co. KG quickly advanced to one of the leading manufacturers of scientific equipment. Over this period of more than 90 years Phywe has been putting quality and innovation into its products as a fundamental requirement. As a well knowninternational supplier in the fields of science and engineering we have made a significant impact on the market through high quality equipment. Phywe products are made in Germany and in use throughout the world in the fields of education and research, from primary schools right through to university level. Up-to-date educational systems, planning and commissioning of scientific and engineeringlaboratories to meet specific requirements are our daily business. As a supplier of complete, fully developed and established systems, Phywe provides teaching and learning systems for students as well as teacher demonstration experiments. The system ranges from simple, easy to operate equipment intended for student use up to coverage of highly sophisticated and specialised university equipment demands.Phywe Systeme GmbH & Co. KG has achieved a very high standard based on research and technology and through exchange of experiences with universities and high schools as well as with professors and teachers. As experienced and competent manufacturer, we would gladly assist you in the selection of the "right" experiments for your particular curricula.
