Purified and wastewaters

• 1 bottle of 13 ml of reagent A
• 1 bottle of 26 ml of reagent B
• 1 bottle of 13 ml of reagent C
• 1 syringe of 5 ml
• 2 test tubes of 20 ml with stopper
• 1 optical comparator
• 1 chromatic scale
• instructions (English)

- The optical comparator in the package allows for color comparison between two test tubes containing the same amount of water, benefiting accuracy.
- The method determines total sulfides, which also includes dissolved H2S. The expression of results is in ppm S.
- The analysis should be performed on the freshly taken sample.

- replacement spectratest Sulfides (Code No.6480) containing:
- 3 bottles reagent Sulfides A
- 3 bottles reagent Sulfides B
- 3 bottles reagent Sulfides C
- Pack of 10 20-mL test tubes (Cod.N° 3310)
