The Sulphite Test Strip is used to detect Sulphite ions in water-based solutions, measuring in increments of 10, 50, 100, 250, and 500ppm.
The Sulphite test strip will detect free sulphite. Detection of combined or total (free + combined) sulphite requires additional sample prep.
Various types of sulphites can be tested with this strip: sulphite, bisulfite, and metabisulfite. Our original colour chart was developed to measure sulphite ions in ppm (from sodium sulphite standards), however, we have checked standards and found that bisulfite and metabisulfite also match the same colour chart.

The Protein test strip detects residual Protein in water in increments of 0.3, 1.0, 3.0, 10.0 plus g/L. If used to test protein in urine, the colour may be more green than blue. If testing urine samples, consider using the Urine Analysis Test Strip. The Protein test strip is based on so-called “protein error of indicators”. This phenomenon relates to the fact that certain pH indicators will change the color at a different pH value in the presence of protein then in the absence of protein. The test is more sensitive to albumin than to globulins, mucoproteins, hemoglobin and Bence-Jones protein. The Protein test strip is strictly for use in education and training students in all levels of medical and clinical-biochemical educational programs. It is not for use in the medical field.
