Folker Steden graduated as a Chemist from the Rheinische Friedrich-Wilhelms University in Bonn Germany.
After finishing his awarded PhD doctoral thesis in inorganic Chemistry at the Universities of Bonn Germany and the Fredericton New Brunswick in Canada he worked as a post-doc at the Department of Chemistry at the Technical University of Dresden. After that period he transferred as the Head of R&D of the green high temperature resistant inorganic fiber manufacturer at belchem, responsible for R&D management, product development and ramp up.
11 years ago he joined SCHOTT as a scientific Consultant for technical and pharmaceutical tubing applications.
In the years 2010 to 2012 he was located in Shanghai responsible for Scientific Consulting, Business Development and B&I activities in Asia.
Since 2012, he is leading the Product Management Team of the tubing division of SCHOTT.
In this position he is working world wide as a “missing link” between customers and local R&D units, focusing on future customer needs and presents frequently on international conferences on subjects related to special glass for technical and pharmaceutical applications.
As the complexity of modern drug products grows from a chemical and physical point of view, the evaluation of possible drug/container interactions are an increasing focus area in primary packaging material development. These interactions mainly depend on several factors: the chemical composition of the glass packaging material, the conversion process (namely the transformation of glass tubing into containers), possible additional surface treatments and, finally, the drug product itself. Regarding the first aspect, the composition of glass varies among different glass types as well as among different manufacturers. In consequence, the composition of a glass gives first indications for potential sources of extractables. A case study will be presented revealing differences in the extractables levels among different glass types, such as borosilicate glass and aluminosilicate glass. Furthermore, also the influence of the conversion process and possible surface treatments on the chemical stability of both glass types will be illustrated.View Details
