Selenium toner concentrate
Dilution 1+10 to 1+400
The legal regulations have changed: Selenium toner based on sodium selenite may now only be marketed in vol % <1. This leads to questions about changing the dilution ratios of this product.
Answer: This product does not contain sodium selenite but sodium selenate, the preparation did not have to be changed. All information on dilution to working solution in instructions and under picture examples is up to date as before.
