Softening Point Apparatus By Rico Scientific Industries

We are highly engaged in providing Softening Point Apparatus.
Heat the material to a temperature between 75- and 100-c above its softening point, stir until it is completely fluid and free from air Bubbles and water, and filter, if necessary, through is Sieve 30 (see IS: 460-1953). Place the rings, previously heated to a temperature approximating to that of the molten material. On a metal Plate which has been coated with mercury or mixture of equal parts of glycerin and dextrin, and fill with sufficient melt to give an excess above the level of the ring when cooled. After cooling for 30 minutes in air, level the material in the ring by removing the excess with a warmed, sharp knife.
