Chemicals marked ** were tested with a saturated cotton wool ball covered by a bottle. All chemicals were tested at room temperature for a period of 24 hours, rinsed off with water and evaluated. Test results The chemicals mentioned in the table include in bold the 49 chemicals/concentrations listed by (Scientific Equipment and Furniture Association) as well as the main reagents from the PSI (Professional Service Industries/Pittsburg Laboratory Division). All information is based on our current state of knowledge. It is intended as information concerning our products and their application possibilities, and is therefore not intended as any form of guarantee with regard to any specific product characteristic. Test results differ per color. Although the tests have been conducted according to the, it is recoended that users conduct their own tests. 2/5
