Method for Removing Contaminants from Laboratory Reactors (Part 1)

　　For long-term use Laboratory Reactor It is crucial to select an appropriate method for cleaning the surface of the reactor vessel. Common methods include mechanical cleaning, chemical cleaning, and solvent cleaning. However, no matter which method is chosen, none is universally effective. For example, solvent cleaning cannot remove corrosion products, steam degreasing cannot remove inorganic contaminants, nor can it remove resin-based contaminants.

　　When selecting a method for cleaning the inner walls of laboratory reaction vessels, consider the following points:

　　1. It is essential to understand the categories of contaminants and select appropriate cleaning methods accordingly. It should be noted that solvent-based cleaning—such as solvent vapor degreasing, ultrasonic cleaning, and water-based detergents—is commonly used to remove contaminants like oils and waxes. Chemical cleaning methods, including alkaline solutions and acid etching, are employed to remove contaminants such as paint, carbon deposits, or other substances that cannot be effectively removed by solvent-based or chemical cleaning alone.

　　2. It is essential to understand the impact of the selected cleaning method on the performance and usability of laboratory reactors. The chosen cleaning method must not damage the sealing surfaces of the reactor body or the reactor lid, thereby preventing any adverse effects on equipment operation.

　　3. It is essential to understand the practicality of the cleaning method chosen—for example, if the vessel being cleaned is too large to fit into an ultrasonic tank for cleaning.
