Jual Destilasi Apparatus Congealing Temperature Di Sulawesi Utara

Similar to Congealing Temperature apparatus described in U.S.Pharmacopeia, 1995, pages 1780, except this apparatus is supplied with Ace-Threds in place of rubber stoppers, where practical. #50 thread at center holds a test tube with a #25 bushing, open top test tube utilizes a rubber stopper to secure a thermometer and wire stirrer, #7 Ace-thred thermometer port on one side, 22mm I.D. opening on the other side to access the 125mm O.D. x 150mm high cylinder. Applicable to substances that melt down between -20 to 150 degree C.

The congealing point of a liquid is the same as the melting temperature of the solid. However, a liquid can be cooled below its congealing point without solidifying.

The congealing temperature of a substance is the maximum point on a temperature-time curve. If there is no maximum, it is the point of inflection.

The congealing point of a mixture is generally a range of temperatures, unlike the well-defined freezing point of a pure substance. However, the congealing temperature can still be a useful index of purity if the heat is released when the substance solidifies.

In pharmaceuticals, the congealing point is the temperature at which a liquid begins to solidify

The congealing point is the average of at least four consecutive readings that are within 0.2°C of each other

The congealing point is the same as the melting temperature of the solid. However, a liquid can be cooled below its congealing point without solidifying
