Determining the drop point of natural resin by automatic drop point determination technology (CAT#: STEM-PPA-0188-LJX)

Introduction

Natural resin refers to the resin obtained from plants, animals, and natural minerals. Plant resins are mainly the secretions of trees (such as pine and peach trees), or the secretions of dead trees are buried in the soil. Animal resins are mainly shellac, a secretion of insects. The natural resin is characterized by being soft when heated, melting, having a tendency to flow under stress, generally insoluble in water, but soluble in alcohol, ether, ketone and other organic solvents.




Principle

During the test, the cup containing the sample is placed on the support, and the furnace is installed on the outside of it. The expected drop point temperature of the sample is set through the instrument keyboard, and the temperature is raised according to the preset heating program. The photodetector automatically records the temperature at which the first drop of sample is dropped from the mouth of the cup, which is the drop point of the sample.

Applications

For drop point determination of non-crystalline materials such as synthetic and natural products

Procedure

1. Place the sample in the cup and put it on the support in the furnace
2. Start the instrument program to heat up
3. The instrument automatically records the temperature at which the first drop of sample drops from the mouth of the cup, that is, the drop point

Materials

• Sample Type:
Natural resin

Notes

The experiment should be repeated three times, and the average value should be taken to ensure the accuracy of the results.
