ST104A Plaster softening point tester
The ST104A plaster softening point tester is designed and manufactured strictly in accordance with the "2025 Chinese Pharmacopoeia 2102 Plaster Softening Point Determination Method". This method is used to determine the temperature of plaster when it softens under specified conditions, that is, the temperature at which the plaster falls by 25mm due to heat is measured according to the following method. Used to detect the age and tenderness of plasters, and can indirectly reflect the viscosity of plasters.
The principle for determining the softening point of plaster is to place the plaster sample in a sample ring, place a steel ball at the center of the plaster sample surface, and place the sample ring with plaster in a water bath from a bracket. As the temperature of the water bath increases, the plaster softens and the steel ball sinks. When the steel ball dragging the plaster sample comes into contact with the bottom plate, the temperature recorded at this moment is the softening point temperature of the plaster.
Main features:
The temperature is controlled by the instrument without any human error.
High precision temperature probe, sensitive to temperature response.
Strong magnetic stirring device, more uniform test temperature
LCD screen can display temperature in real-time.
Can measure high temperature, medium is water or glycerol. (Water is recommended for temperatures below 90 degrees Celsius, and glycerol is recommended for temperatures above 90 degrees Celsius)
