Double-layer glass reactor is also called jacketed glass reactor, which is mainly composed of high borosilicate glass reactor body and movable stainless steel frame. It takes advantage of the characteristics of double-layer glass, placing high-temperature oil or cooling liquid in the middle of the two layers of glass to heat or cool the reaction materials in the kettle, and the materials in the kettle are uniformly stirred under normal pressure or negative pressure. In this way, the materials can react in the glass reactor to achieve heating or cooling. Glass reactors are commonly found in related industries such as biomedical and chemical industries, and are indispensable tools for modern industries.
Of course, this kind of easy-to-use tool will also have various faults and problems, but most technicians can solve it. Now let's talk about the common faults and solutions of the jacketed glass reactor.
I. Air leakage in various valves
Cause of failure: damaged valve or PTFE seal
Solution: Through observation and simple detection, confirm that the valve or PTFE is damaged, and contact the manufacturer for replacement in time.
II. The inner magnet steel does not rotate, but the outer magnet steel rotates, and the motor current becomes smaller
Cause of failure: The temperature in the glass reactor is too high, and the inner magnet steel is demagnetized due to high temperature. Hydrogenation reaction occurs, and the internal magnetic steel expands and breaks.
Solution: contact the manufacturer for replacement.
III. Poor sealing at the junction of the kettle cover
Cause of failure: Impurities in the connection or the glass itself is not smooth
Solution: Clean the impurity at the connection, and if this method does not work, please contact the manufacturer's technicians.
IV. Slow heating
Cause of failure: poor insulation of the kettle body, or failure of the temperature control meter
Solution: Install an insulation cover (generally provided by the manufacturer), and if the temperature control meter fails, please contact the manufacturer.
V. Poor mixing effect
Cause of the failure: the power of the stirring motor is low or the stirring blade is not suitable, and the viscosity of the material is too high.
Solution: Replace the high-power motor or mixing paddle. If the viscosity of the material is too high, please consult the manufacturer for a solution.
