Product Description Product Description-The digital melting-point apparatus is a device used in laboratories to determine the melting point of a substance. It is an upgraded version of the traditional melting-point apparatus, which used a mercury thermometer and a heating source to measure the temperature at which a solid substance changes from a solid to a liquid state.-The digital melting-point apparatus consists of a heating block, a sample holder, and a temperature sensor. The heating block is equipped with a heating element that provides controlled and precise heating to the sample. The sample holder holds the substance being tested and is inserted into the heating block. The temperature sensor is connected to a digital display, which shows the real-time temperature of the sample. 1. Basic Concept: What is Melting Point?The melting point refers to the temperature at which a substance changes from a solid to a liquid state under standard atmospheric pressure. Pure substances have a fixed melting point with a short melting range (the temperature interval from the start to complete melting, usually ≤0.5oC). In contrast, substances containing impurities have a lower melting point and a longer melting range. Therefore, melting point determination is an important method for judging substance purity and identifying substances.2. Working PrincipleThe core principle of a melting point apparatus is to determine the melting point by heating the sample and real-time monitoring the sample's temperature and state changes. The specific process is as follows: A small amount of solid sample is loaded into a capillary tube, compacted, and placed in the heating device.The instrument heats at a set rate (e.g., 1oC/min, 2oC/min), causing the sample temperature to rise gradually.When the sample starts to melt (the first drop of liquid appears), the initial temperature (onset melting temperature) is recorded; when the sample is completely melted (the solid state disappears), the final melting temperature (complete melting temperature) is recorded. The interval between the two is the melting range.Modern melting point apparatuses usually observe the sample state through an optical system (such as a camera or magnifying glass) or monitor temperature changes through sensors (such as thermocouples or infrared detectors) to achieve automatic recording.Detailed Photos Product ParametersMelting point test rangeroom temperature ~ 350oCMelting point test accuracy≤200oC ±0.5oC≤100oC ±1oC≤350oC ±1oCHeating rate3.0oC-5oC/minVolume40 * 25 * 30cmPower220V/50HZCompany ProfilePackaging & ShippingFAQ
