Determining the drop point of lignite wax by Ubbelohde method (CAT#: STEM-PPA-0200-LJX)

A dedicated one tenth of a degree resolution thermometer is directly immersed in contact with the sample residing in a cup. The setup is positioned in a test tube and the heating is performed with a water bath. The drop point temperature should be recorded as soon as the first drop of sample is visually detected. The results of this test are strongly dependent on the operator's experience.

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

1. A dedicated one tenth of a degree resolution thermometer is directly immersed in contact with the sample residing in a cup.
2. The setup is positioned in a test tube and the heating is performed with a water bath.
3. The drop point temperature should be recorded as soon as the first drop of sample is visually detected.

• Sample Type:
Lignite wax

Manual methods require visual inspection of the dropping point process, which is tedious as the attention of an operator is required for quite a long time to continuously monitor the test process.
