Test strips, tumeric paper for qualitative detection of borates
Environmental Test Kits
The test paper allows the quick and easy detection of boric acid and borates. It is impregnated with curcumin, the yellow dye extracted from the roots of Curcuma tinctoria (yellow ginger).

  • Colour changes: Yellow to red

The paper is dipped into the sample containing hydrochloric acid (pH 1 to 2). Afterwards it is allowed to dry.

In presence of borate the paper turns orange to red. Dipping into conc. sodium hydroxide causes a green-black colour. In the absence of borate, sodium hydroxide leads to a brown-red colour.

Packaging: Pack of 200 strips 20x70 mm.
