Product Description

Products Description of Zinc Sulphate CAS#7733-02-0

Zinc sulphate (white vitriol) is a white crystalline water-soluble salt, typically supplied as the heptahydrate (density ~1.9). It dehydrates sequentially with heating and decomposes above 500 °C. Used as a dyeing mordant and styptic.


Product Applications of Zinc Sulphate CAS#7733-02-0

Zinc sulphate is used in fungal growth culture media, as a zinc supplement for zinc-containing protein expression (with IPTG), and for blood sample deproteinization (with barium hydroxide) in Somogyi–Nelson glucose assays.
