Profile: Integrated Scientific Ltd. is a supplier of automated petroleum test equipment for the petrochemical offshore and refining industries. We are an ISO 9002 certified company. In our cold behavior measurement, pour point, cold point, freeze point, and cold filter plugging point are used to determine the flow characteristics of petroleum at low temperatures. These measurements basically define the lowest temperature at which the product can be used in the intended application. Cloud point is the temperature at which the formation of wax crystals begins to affect the product's flow characteristics, particularly through small orifices and filters.
