Freezing point apparatus

Freezing point apparatus determines the temperature at which liquids solidify, ensuring quality control and performance consistency in oils, fuels, and chemicals.

Freezing point apparatus

Compliance Standard : ASTM D1177 – Standard Test Method for Freezing Point of Aqueous Engine Coolants, ASTM D2386 – Standard Test Method for Freezing Point of Aviation Fuels, IP 16, IS 1448 (P-10) (where applicable)
Application : The Freezing Point Apparatus is used to determine the freezing point of engine coolants, antifreeze solutions, aviation fuels, and petroleum-based liquids. It is widely used in petroleum refineries, aviation fuel testing laboratories, lubricant and coolant manufacturers, R&D centers, and quality control laboratories to evaluate low-temperature performance and ensure compliance with industry standards.

Product Description : The Freezing Point Apparatus is a robust and precision-engineered unit designed for accurate determination of freezing point using a controlled cooling bath method. The apparatus consists of a well-insulated refrigerated bath, test jar assembly, precision thermometer holder, and a mechanical stirring system to ensure uniform cooling. The unit provides stable and repeatable temperature control at sub-zero conditions, allowing clear observation of crystal formation as specified in ASTM D1177 and ASTM D2386. Its rugged construction and simple operation make it suitable for both routine quality control and research applications.
