Saybolt Viscometer

The Saybolt Viscometer manufactured by Glass Agencies is widely used in petroleum testing laboratories, oil refineries, research institutions, and quality control departments for determining the viscosity of petroleum products such as lubricating oils, fuel oils, and other liquid hydrocarbons. Viscosity is an important physical property that indicates the resistance of a liquid to flow. Measuring the viscosity of petroleum products helps technicians understand how the oil behaves during pumping, lubrication, and engine operation. This information is important for evaluating the performance characteristics of oils used in automotive engines, industrial machinery, and hydraulic systems. The Saybolt Viscometer operates by measuring the time required for a specific quantity of liquid to flow through a standard orifice under controlled temperature conditions. During the test, the oil sample is placed in a test cup provided with a precisely sized outlet at the bottom. The cup is surrounded by a temperature controlled bath which helps maintain the required testing temperature. Once the sample reaches the desired temperature, the outlet is opened and the liquid is allowed to flow into a receiving flask placed below the cup. The time taken for a fixed volume of the liquid to flow through the orifice is measured using a stopwatch. This time is recorded in Saybolt Universal Seconds or Saybolt Furol Seconds depending on the type of orifice used in the apparatus. Glass Agencies manufactures the Saybolt Viscometer using carefully selected materials suitable for petroleum testing laboratories and research facilities. The apparatus structure includes a test cup assembly, temperature controlled bath, thermometer holder, receiving flask, and supporting frame that allows the testing process to be carried out in a systematic manner. The arrangement of the equipment allows technicians to observe the flow of the liquid clearly while maintaining stable temperature conditions during the test. The compact design allows the apparatus to be installed conveniently on laboratory workbenches without occupying unnecessary space.
