According to the article “An Evaluation of the Precision of Reference Test Methods Used in the Analysis of Milkfat in Laboratory Control Samples”, published in the August 1986 Dairy and Food Sanitation magazine, the following modification was specified ”...adjusting of the specific gravity of the sulfuric acid to 1.825...” Our product is guaranteed to be clean, colorless and standardized at specific gravity 1.825. Using Babcock acid that is always the exact same strength from one lot to the next saves a great deal of time in determining the amount of acid to be used to standardize the measurement of the milk/acid reaction temperature.

Products so identified must ship as hazardous materials (HAZMAT). We welcome you to contact our Customer Service department for additional details about HAZMAT shipping requirements and surcharge fees. In general, HAZMAT fees apply whenever shipped by either UPS or FedEx, currently $44.00 per shipping carton for ground shipment. Air shipments require a $130.00 fee. To avoid most HAZMAT fees, if your order contains hazardous materials that require four or more shipping cartons, we will route via common carrier, which may not have any, or have greatly reduced, HAZMAT fees. Additionally, some products identified as HAZMAT may qualify for “Limited Quantity” regulations, eliminating the need for HAZMAT fees. HAZMAT orders are exempted from our 1-2-3 Day Delivery Program.
