Congealing point apparatus

Congealing point apparatus determines the temperature at which oil solidifies by cooling the sample under controlled conditions and noting when flow stops.

Congealing point apparatus

Compliance Standard : Astm D938
Application                  : Determination of congealing point for petroleum waxes, lubricating oils, and fuel oils, Quality control in petroleum refineries and lubricant manufacturing, Research and development of waxy and lubricating products, Ensuring compliance with international petroleum product standards

 

Product Desciption : The Congealing Point Apparatus is a laboratory instrument designed to determine the congealing point of petroleum waxes, lubricating oils, and other petroleum products. The congealing point is the temperature at which the wax or oil solidifies under controlled conditions, which is a critical parameter for quality control, formulation, and specification compliance. The apparatus is constructed with high-quality materials to ensure accurate, reliable, and repeatable measurements.
