The Master Science Dropping Point Apparatus determines the dropping point and softening point of amorphous and highly polymerised materials using photoelectric detection and a programmed heating ramp. The method follows the principle of ASTM D3461.
It is widely used for quality testing of tar, asphalt, paraffin, resins, rosin, fats, lubricants, petroleum jelly, pharmaceutical ointments, suppositories and edible greases.

Common Laboratory Problems and How This Apparatus Helps
How the Master Science Dropping Point Apparatus improves softening point testing:
- Visual ring-and-ball readings vary: photoelectric detection is objective.
- Uneven heating: programmed ramps keep conditions repeatable.
- Different equipment for each test: one unit performs dropping and softening tests.
- Slow manual observation: automatic detection frees the operator.
- Record keeping: digital display shows precise values.
