K-9203 Sulfate

K-9203 Sulfate Vacu-vials Kit was designed to obtain Sulfate levels from 0-100.0 ppm

Sulfate Information


The K-9203 Sulfate Kit was designed to accurately measure the levels of Sulfate in water from 0-100.0 ppm. K-9203 uses the Turbidimetric Method. Sulfate ion reacts with barium chloride in an acidic solution to form a suspension of barium sulfate crystals of uniform size. The resulting turbidity is proportional to the sulfate concentration of the sample. Results are expressed as ppm (mg/L) SO4.

Sulfate is present at widely varying concentrations in natural waters. The USEPA has established a Secondary Drinking Water Standard of 250 mg/L for sulfate in potable water, as higher concentrations affect odor and taste. Sulfate levels are also measured in the beverage industry due to its effect on odor and taste. Sulfate levels must be monitored in cooling water and ion exchange systems in order to prevent calcium sulfate scale formation

What's included:

  • 30 Ampoules
  • 25 mL Sample Cup 
  • Activator Powder
  • Acidifier Solution
  • Ampoule Blank
  • Instruction Manual


How to use:

  1. Put the Zero ampoule into the device and cover with the light shield piece to zero out the unit. (NOTE: This must be zeroed any time the unit is turned off and turned back on)
  2. Fill to the 20 mL mark in the sample cup with sample water.Fill the sample cup to 25ml
  3. Add 7 drops of Acidifier Solution and stir gently.
  4. Add 1 scoop of Activator Powder and stir gently for 10 seconds.
  5. Snap the end of the Vacu-vial in the water on the bottom/side of the 25 mL sample cup.Snap the tip of the ampoule on the bottom and side of the sample cup
  6. Mix the contents of the ampoule by tipping back and forth a few times.Tip the vacu-vial back and forth to mix
  7. Dry the vacu-vial and wait 1 minute for color development.Dry vacu-vial and then insert into the I-2019
  8. Place the vacu-vial ampoule into the device (flat end first) for readout.
