Digital automatic Melting point Apparatus
According to the definition of physical chemistry, the melting point of a substance is the temperature when the substance is turned into a liquid state. In the field of organic chemistry, melting point determination is the basic means of identifying material nature and is one of the important methods of purity determination. As a result, the melting point apparatus is important in chemical industry and medical research, and is a necessary instrument for producing drugs, spices, dyes and other organic crystals.
Measurement of melting point is one of the important methods of measurement of purity;
To be used in production of medicines, dye-stuffs, perfumes and other organic crystal substances;
Real time melting curve.
1.The sample is best filled with five capillaries, and the mean value of the three readings in the middle is measured as the measurement result to eliminate the accidental error caused by the preparation of the capillary and sample preparation.
2.Use a soft cloth to remove dirt from the outside to prevent oil bath from getting dirty.
3.If you need to replace the oil bath tube, please use the method described in the preparation before use.
Preparation before use
Note: before entering the formal test, the preparation work must be carried out before use.
1. The filling of silicone oil
(attachment) from silicone oil with a syringe (attachments) 10 ml from the spillway injection, repeat 6 times, total pay 60 ml silicone oil injection, then put the spilled oil bottle set on the spillway (such as long-term measurement of melting point is lower than 90 ℃, can use distilled water instead of silicone oil).
2. Oil bath tube replacement
First remove the overflow bottle and remove the side plate.
Put your hand into the chest of the instrument, hold the oil bath tube in one hand, pull the spring in one hand, then remove the oil bath tube horizontally, and take out the oil bath tube carefully, so as not to break the glass.
