“No other glass than violetglass offers the unique combination of absolute light protection against light penetration if the visible range and light penetration of the UV/Violet- and Infrared range.”
The qualities of the violetglass are examined by several prominent institutions.

• by the 'Interstaatlichen Ingenieurschule Neu Technikum', Buchs (St. Gallen),
• by 'Frauenhofer Institute for Food technology und packing', München,
• by 'International Institute for Bio-Physics', Kaiserslautern (Photonenemissionsmessungen von Prof. Popp)
• by glass manufacturer Heinz', Kleintettau.

The institutes came to the same conclusion:
Violetglass is for the high-sensitive particles with in distance the best conservation and optimal bio-protect available.
