AT821 Dropping Point and Softening Point Tester is used for composition control and quality inspection of tar, asphalt, paraffin, resin, rosin, grease, Vaseline, ointment, ointment, suppository, ointment, edible oil, etc. Determinate the drop point and softening point of amorphous polymers, physical and chemical properties such as density, polymerization degree and heat resistance
It can replace the traditional Ubbelohde drop point determination and global softening point determination.
