6.1D: Step-by-Step Procedures for Melting Point Determination
WEBMelting Point Apparatus; Thiele Tube Method; Melting Point Summary; There are a variety of methods by which a sample's melting point can be measured, with the newest being electrical probes (e.g. Vernier MeltStation). Presented in this section are traditional methods that use an electrical melting point apparatus and Thiele tube.

WEBAug 28, 2022 · Simply prepare standards with known molar fraction ratios, then perform melting point analysis on each standard and plot the results. Compare the melting point range of the experimental sample to the curve to identify the approximate molar fractions of the constituents.
Melting-point apparatus - Wikipedia
WEBA melting-point apparatus is a scientific instrument used to determine the melting point of a substance. Some types of melting-point apparatuses include the Thiele tube, Fisher-Johns apparatus, Gallenkamp (Electronic) melting-point apparatus and automatic melting-point apparatus.
WEBdescribe two common methods for determining melting point using i a Meltemp apparatus and ii a Thiele tube set up. The temperature at which a solid melts and becomes a liquid is the melting point.
WEBcompounds that are solids at RTP have melting points lying between 30°C and 350°C, most solid-state inorganic compounds either have ex-tremely high melting points, sometimes ap-proaching several thousand degrees, or else thermally decompose before melting. Simple Apparatus for Melting-Point Determinations
Mel-Temp Melting Point Apparatus - orgchemboulder.com
WEBThe picture below shows a Mel-Temp melting point apparatus. This type of melting point apparatus uses long, thin melting-point capillaries. Note that you have to turn on both the heating block (green switch) and the thermometer (small switch on top) if your Mel-Temp has a digital thermometer. If your Mel-Temp has a traditional mercury ...
WEBOne usually determines a melting point by immersing a capillary tube containing a small sample of the solid in an oil bath fitted with a thermometer, then slowly heating the oil until the solid melts. The Thiele tube shown in Figure 11a is probably the most commonly used melting-point apparatus in undergraduate
