QUANTOFIX Sulfite Test Strips
$44.90
Semi-quantitative sulfite test strips, 0-1000 mg/L SO3 2-, 100 strips.
QUANTOFIX Sulfite test strips give a semi-quantitative reading of sulfite in solution from 0 to 1000 mg/L. Acidic samples must be buffered with solid sodium acetate before testing, since the paper does not react with sulfite in acidic media. Sulfide interferes and can be removed with excess nickel(II) ions and filtration.
The supplier labels this item for research purposes.
