In the laboratory, the intelligent graphite digester is widely used in various fields due to its uniform heating and rapid heating characteristics, providing an efficient and reliable solution for the drying, heating and constant temperature of experimental samples. However, we may not yet fully understand the properties of the constituent materials of the smart graphite digester, especially the Teflon coating. Here, we will explain the application of Teflon coating in a smart graphite digestion instrument.
The Teflon coating is still relatively unfamiliar to some people, but I say it is a black non-stick coating, which may be more familiar to you. It is more common in the rice pot where we cook rice.
The intelligent graphite digester uses Teflon coating, which is mainly based on the following considerations:
1.Non-stick: The surface of the Teflon coating is hydrophobic and oleophobic, making it less prone to adhesion of sample residues during use. This is critical for the cleaning of the digester, especially at high temperatures involving acids and alkalis, and with the Teflon coating, cleaning is simple and easy.
2.High temperature resistance: Teflon has a very high melting and autoignition point, so the coating remains stable at high temperatures. The operating temperature of the intelligent graphite digester is high, and the Teflon coating can easily cope with it, with an operating temperature of up to 290 degrees and even an intermittent operating temperature of 315.
3.Chemical resistance: Teflon coatings are corrosion-resistant to most chemicals. Only molten alkali metals and fluorinating agents at high temperatures have an effect on it. Therefore, when doing highly corrosive experiments, it is important to have a Teflon coating.
Through the combination of the above Teflon characteristics, the experience of using the intelligent graphite digester has been improved. When sourcing and selecting instruments, smart graphite digesters with Teflon coatings ensure efficient laboratory work.
