Capillary Melting Point Analyzer

The capillary melting point analyzer detects the purity and thermal stability of substances by heating a sample tube and observing the temperature at which the solid liquefies. It is used in the chemical and pharmaceutical industries for raw material identification and quality control.
Selection
When selecting, consider that the temperature range should cover the melting point of the sample, adjustable heating rate ensures accuracy, the clarity of the observation system affects judgment, the sample amount should match the capillary specifications, and the calibration function ensures data reliability.

Comparison of Rotational Viscometer and Capillary Rheometer in Testing the Flowability of Resin Processing
The rotational viscometer measures torque via rotor rotation, making it suitable for testing the static or low-shear fluidity of resins under low shear rates, with simple and quick operation. The capillary rheometer, on the other hand, forces samples through a capillary to simulate high-shear processing, providing flow data closer to actual production conditions, but it is more complex and time-consuming to operate.
Capillary Rheometer for Determining the Shear Viscosity Curve of Hot Melt Adhesives
This article introduces the method of measuring the shear viscosity curve of hot melt adhesives using a capillary rheometer. The principle involves pushing molten hot melt adhesive through a capillary, measuring the pressure and flow rate, and then calculating the shear stress and viscosity.
Differential Scanning Calorimetry for Determining the Melting Point and Glass Transition Temperature of Hot Melt Adhesives
This article introduces the method of determining the melting point and glass transition temperature of hot-melt adhesives using a differential scanning calorimeter. Differential scanning calorimetry analyzes the thermal transition characteristics of materials by measuring the energy difference between the sample and a reference material.
The main issue with using a Ubbelohde viscometer is that 90% of capillary blockages are caused by inadequate sample filtration.
More than 90% of capillary blockage in Ubbelohde viscometers during measurement is due to inadequate sample filtration. Minute particles or gels in the sample tend to adhere to or become trapped when flowing through the narrow capillary, leading to abnormal flow rates and affecting measurement accuracy.
