Ultrasonic microwave chemical reactor

The new variable frequency microwave chemical reactor adopts microcomputer technology and variable frequency microwave adjustment technology to realize microwave power variable frequency adjustment. The whole series of products have precise temperature control and magnetic stirring functions, digital display of temperature and magnetic stirring speed, simple operation and good repeatability. For experiments that need to explore microwave catalytic reaction conditions, especially for chemical experiments that require smaller microwave power but hope to maintain continuous microwave radiation, its scientificity and practicality are ideally exerted.

Main technical features and descriptions:

(1) Automatic variable frequency control of microwave power:

Adopting the latest variable frequency technology, the 50Hz industrial frequency is converted into a variable frequency of 10,000 to 30,000Hz through the inverter, replacing the high-voltage transformer used in traditional microwave reactors, perfectly solving the technical defect that the high-voltage transformer is frequently damaged by the impact of spike pulses when the traditional microwave reactor is precisely controlled. MCU adjusts PID adaptively and automatically controls microwave output power based on temperature change data detected in real time by Pt100 sensor, polarity of reaction material, heat capacity change, reaction time and other mathematical model change conditions, so as to accurately control temperature.

(2) Digital display speed magnetic stirring:

The bottom of microwave reaction cavity is equipped with magnetic stirring, which adopts high temperature resistant samarium cobalt magnet, with maximum working temperature up to 350℃, no demagnetization after long-term use, stepless speed regulation and speed digital display.

(3) Open reaction system:

Users can add standard reaction container (volume 100-500ml) and condensation reflux, dripping, liquid replenishment and water separation devices according to reaction conditions, and equipped with protective gas inlet.
