Sulfite Test

Sulfites are used to remove dissolved oxygen from the treatment water. Excess sulfite at elevated temperature combines with oxygen to reduce pitting. Remember to cool your samples quickly and perform the test immediately. Each kit is packaged in a durable plastic case and includes all items to…

Sulfites are also used as regulated food preservatives/additives/enhancers in dried fruits, wine, beer, etc. They are considered as GRAS (Generally Recognized as Safe) in food and beverages. In wine, SO2 reacts with sugars, aldehydes and anthocyanins. The term sulfite is used for all…
