SCHOTT Technical Glasses
Apart from its application in optics, glass as a technical material has exerted a formative influence on the development of important technological fields such as chemistry, pharmaceutics, automotive, optics, optoelectronics and information technology. SCHOTT Technical Glasses offers pertinent information in concise form. It contains general information for the determination and evaluation of important glass properties and also informs about specific chemical and physical characteristics and possible applications of the commercial technical glasses produced by SCHOTT. With this brochure, we hope to assist scientists, engineers, and designers in making the appropriate choice and make optimum use of SCHOTT products.

respectively.<br />
Syringes made from FIOLAX ® neutral glass tubes<br />
FIOLAX ® tubes guarantee highest quality and outstanding<br />
chemical stability. Containers made from these glasses,<br />
sometimes also called “neutral glasses,” fulfill all the specifications<br />
listed in the European Pharmacopoeia and in the<br />
various pharmacopoeia of other nations.<br />
