A melting point apparatus is a machine that helps chemists determine the identity of the compound based on what temperature it turns from a solid to a liquid. Most elements and compounds have a specific temperature at which it melts. Small amounts of whatever is tested is inserted into small, thin tubes and inserted into the machine.
· After connecting the Melting Point Apparatus instrument new screen shall open requiring User Name and Password. Then go to the Instrument Name shown as MRVIS +. After clicking MRVIS + option bulb shall glow green and it indicates right selection of the Melting Point Apparatus instrument under operation.
Melting point apparatuses determine the melting point of a substance. Most melting point apparatuses have a unique exterior look, but the interiors all house a melting point capillary. The solid sample is sealed inside the capillary and placed inside the apparatus. The sample is heated by an oil or heating block.
design of the melting point apparatus and for performing the measurements. Automated melting point determination procedures are generally included. Very often, the pharmacopeias also list special methods for difficult or unusual cases of melting point determination.

2.2.16. MELTING POINT - INSTANTANEOUS METHOD The instantaneous melting point is calculated using the expression: in which t1 is the first temperature and t2 the second temperature read under the conditions stated below. Apparatus. The apparatus consists of a metal block resistant to the substance to be examined, of good heat-conducting
Mel-Temp Melting Point Apparatus. The 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.
Description: The Melting Point M-565 is for automatic determinations of both melting and boiling points and is designed for true, professional quality control. ,97039-680EA,97039-696PK,97039-694PK,89034-278EA
The melting point accessories box contains two sets of 150 melting point capillaries each, three METTLER TOLEDO melting point reference substances or USP melting point reference standards, an agate pestle and mortar, tweezers, a spatula, and 5 capillary filling tools (Picture 1):
Figure \(\PageIndex{2}\) Schematic showing how to pack dried sample into a melting point analysis capillary tube: (a) using a spatula, push a sufficient amount of sample into the tube opening, (b) using a tapping motion or dropping the tube, pack the sample into the closed end, (c) the sample is ready to be loaded into the apparatus.

Berdasarkan teori, titik leleh asam salisilat adalah 159 o C. Dari percobaan yang kami lakukan dengan menggunakan alat melting point apparatus. Pada percobaan, didapatkan suhu awal asam salisilat adalah 162 0 C. Asam salisilat mulai meleleh pada suhu 200 0 C serta didapatkan dalam keadaan meleleh sempurna pada suhu 204 0 C. Range yang .
Derivatives having a hydroxyl group are 1-hydroxyanthracene and 2-hydroxyanthracene, homologous to phenol and naphthols, and hydroxyanthracene (also called anthrol, and anthracenol)[21][22] are pharmacologically active. They can exist in over 100 different combinations but the most common are treated as a group of 15. Transition enthalpy. …

It is non-water miscible and has a flash point of approximately -45°F, varying with octane rating. Gasoline has a vapor density between 3 and 4. Therefore, as with all products with a vapor density greater than 1.0, gasoline vapor s will seek low levels or remain close to ground level. Gasoline has a specific gravity of 0.72–0.76
Galvanizing is a coating of zinc metal that is applied to the steel when it is manufactured, either in a hot dipped fashion or by electroplating. Zinc is a bluish, white metal, its melting temperature is 950 degrees F. and boils or vaporizes at 1350 F. Zinc, when used as a galvanizing coating, protects steel from rust.
