Dairy

Dairy reagents are prepared solutions for the routine tests run on milk and milk products. Dairy processors, creameries and food testing laboratories use them for fat determination and related compositional checks.

The 23 Reagecon listings include Gerber test sulphuric acid with a density of 1.815-1.825 (FMT), the reagent at the heart of the Gerber method for milk fat, offered in more than one pack size. Copper sulphate solutions are also listed, both as a 1% solution and as solution B at 72.5 g/L, for methods that call for a copper-based reagent.

When ordering Gerber acid, confirm the density range stated on the product matches your method, since the result depends on it. For copper sulphate, pick the concentration your procedure names rather than the nearest alternative. Dairy laboratories that also calibrate pH and conductivity meters will find those standards under Electrochemistry. Ask for a quotation on regular volumes.
