Why is it important to know  carbonizable substances in white mineral oil or paraffin wax?

This test method is a means for ascertaining whether pharmaceutical mineral oil (ASTM D565) or paraffin wax (ASTM D612) conforms to the standards of the United States Pharmacopeia, the National Formulary, and the Food and Drug Administration.

Summary of the test methods

For the test, either mineral oil (ASTM D565) or melted paraffin wax (ASTM D612) is treated with concentrated sulfuric acid (H₂SO₄) and heated under prescribed conditions. The resulting colour is compared with a reference standard to determine whether it passes or fails the test.

Why should you use a  Tamson Dupont bath?

The very good insulated Tamson TC16 bath is the most robust in the market with the widest temperature range from ambient +5°C to 250°C and the TC16 is suitable for immersing test tubes. The levelling platform (P/N 07T0210) will keep the test tubes above the 10 mL line and is needed as an accessory. A special stainless steel cover (P/N 03T2314) with eight 16 Ø mm holes is needed to suspend the test tubes insix openings. All essential parts of the TC16 bath are made from stainless steel. The bath has a standard drain to empty the bath content. All the required accessories and consumables for ASTM D565 and ASTM D612 are supplied by Tamson.
