Use and Maintenance of Laboratory Magnetic Stirred Reactors (Part 2)

　　In the previous article, we discussed the precautions that should be taken when using and maintaining laboratory magnetic stirrer reactors. Now, let’s talk about the issues that need to be addressed during the initial use of this equipment in the laboratory.

　　1. For users who are new to magnetic stirrer reactors, it’s essential to carefully familiarize yourself with the equipment’s functional specifications before use, including: operating pressure, operating temperature, corrosion resistance of the main material, functionality of openings on the reactor lid and whether it features a distillation cooling system, cooling and heating methods inside the reactor, type of valve used at the discharge port, stirring speed, and the viscosity range suitable for the agitator blade’s operation.

　　2. You should also thoroughly understand the equipment’s instruction manual and the solutions to common problems.

　　3. Before officially starting up the magnetic stirring reactor, it is essential to conduct a thorough training run of the equipment, focusing primarily on the heating system, the stirring system, the pressure protection system, and the control system as a whole. This training run will help identify the most suitable parameter settings for matching the equipment with the specific experimental process.

　　4. For controlling the heating rate (in the case of electric heating), the heating rate is primarily regulated by the voltage meter reading. As for the stability of the heating temperature, it should be determined based on the changes in the ammeter’s needle.
