HCK Colortest Silica

Measurement of the color intensity of the blue complex formed by reduction of Silicomolibdic acid previously obtained by the reaction of Silica with Ammonium Molybdate.

- The method is very sensitive and allows even lower concentrations than indicated to be detected by comparison. For this purpose, it is sufficient to observe the color from above in a layer of 5 to 10 cm, in a perfectly transparent test tube, on a white background, adjusting the number of drops of reagents to the amount of sample used.
- The optical comparator contained in the package allows for color comparison between two test tubes containing the same amount of water, benefiting accuracy.
- HYDROCHECK kits (which can be purchased directly) allow for many precise analyses at a very low cost per analysis. If accuracy is not particularly important and there are few analyses to be performed, it may be worthwhile to use DROPS kits, whose cost per package is considerably lower (to be purchased through dealers).
