What Are They?

A platinum crucible is a container used to hold samples during thermoanalytical measurements. To use it correctly, the crucible must be preheated before the sample is put inside of it. Once the sample is placed in the crucible and covered with a lid, the sample should be heated at a very precise rate dictated by the required experiment protocol. When finished, add in any additional substances and slowly cool down the platinum crucible before retrieving your sample.

A platinum crucible is a type of laboratory equipment used for high-temperature thermal analysis of substances. It can be used in a number of ways, such as with thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) to measure characteristics such as mass loss, chemical composition, sample purity, kinetic energy and melting point. To use the gold crucible, place sample in crucible, add lid, position on furnace plate, heat according to predetermined program settings and observe results via analytical instrument. It is a useful tool in thermogravimetric analysis (TGA) and thermogravimetric-differential scanning calorimetry (TGA/DSC). When performing these measurements, they should be used at temperatures of 640 degrees Celsius or higher.

How to Use Them Properly?

Platinum crucibles are used in high temperature laboratory applications due to their excellent performance up to 1600 °C. Proper care must be taken when using a platinum crucible, such as cleaning and preventing oxidation, as well as methods for safely handling and disposing of it if necessary. When heating materials, the crucible should be heated slowly and evenly to prevent cracking or damage to the crucible. Additionally, the user must wear proper safety gear while working with a platinum crucible at high temperatures. It is used to hold substances for heat processes such as burning, melting, and refining at high temperatures. It is essential to choose an appropriate size for the appropriate volume of material. For up to 150 microliters volume, a smaller size should be chosen to increase sensitivity and accuracy. Platinum crucibles are used in a variety of laboratory applications due to their low mass and high melting point. Proper use of platinum crucibles is necessary to successfully achieve the desired results.
