Drop Point Apparatus

The Drop Point Apparatus manufactured by Glass Agencies is widely used in petroleum laboratories, research institutions, and industrial quality control departments for determining the drop point of lubricating grease and similar semi solid materials. The drop point of a substance is the temperature at which the material changes from a semi solid state to a liquid state and forms a drop under controlled heating conditions. This test helps technicians understand the temperature at which grease begins to lose its structural stability. The result obtained from this test provides useful information about the thermal behavior of lubricating greases used in machinery, automotive components, and industrial equipment. The Drop Point Apparatus operates by gradually heating a small sample of grease placed inside a special test cup that has a small opening at its base. The test cup containing the sample is positioned within a heating assembly along with a thermometer that records the temperature during the experiment. As the temperature increases steadily, the grease sample softens and eventually begins to melt. At a certain temperature, the melted grease forms a drop and falls through the opening at the bottom of the cup. The temperature recorded at the moment the first drop falls is identified as the drop point of the grease sample. This measurement helps laboratories evaluate the high temperature performance of lubricating greases used in various mechanical systems. Glass Agencies manufactures the Drop Point Apparatus using carefully selected materials suitable for laboratory environments where controlled heating tests are conducted. The apparatus structure includes a heating unit, sample cup holder, thermometer support, and a stable base that allows the test to be performed safely and conveniently. The design of the apparatus allows technicians to observe the melting behavior of the sample clearly while maintaining steady heating conditions during the experiment. The compact arrangement allows the equipment to be placed easily on laboratory workbenches without occupying excessive space.
