Cloud and Pour Apparatus

The Cloud and Pour Point Apparatus manufactured by Glass Agencies is widely used in petroleum testing laboratories, research institutions, and quality control departments for determining the cloud point and pour point of petroleum products such as lubricating oils, diesel fuel, and other liquid hydrocarbons. These tests are important for evaluating the low temperature behavior of petroleum products. The cloud point is the temperature at which wax crystals first begin to appear in the oil when it is cooled under controlled conditions. The pour point is the lowest temperature at which the oil remains capable of flowing. These measurements help technicians understand how petroleum products perform in cold environments where flow characteristics are critical. The Cloud and Pour Point Apparatus operates by gradually cooling a sample of the petroleum product placed inside a test jar. The jar containing the sample is positioned within a cooling bath where the temperature can be reduced in a controlled manner. During the test, the sample is observed at regular temperature intervals. When the first signs of cloudiness appear in the sample due to the formation of wax crystals, that temperature is recorded as the cloud point. The cooling process continues further until the sample becomes thick and stops flowing when the test jar is tilted. The temperature at which the sample no longer flows is recorded as the pour point. These observations help laboratories determine the low temperature performance of petroleum oils. Glass Agencies manufactures the Cloud and Pour Point Apparatus using carefully selected materials suitable for petroleum testing laboratories. The apparatus includes a cooling bath, sample jars, thermometer supports, and a stable structure that allows the testing procedure to be carried out under controlled conditions. The arrangement of the apparatus allows technicians to observe the sample clearly while the temperature is gradually reduced during the experiment. The compact design allows the equipment to be placed conveniently on laboratory workbenches without occupying unnecessary space.
