China glass chemical vacuum reactor|ZZKD Instrument
With the continuous development of the economy, the glass chemical reactor has been widely used in laboratory equipment testing, such as fine chemicals, chemical and biopharmaceutical new materials, because of its constant rotation speed, no brush, no spark, safety and stability. Trial and production. Although its application is very extensive, many users do not really understand the operational process considerations and common faults. In the event of a breakdown, a dedicated technician will be required to refurbish. Do you want to solve the faults that occur during use? Do you want to be a professional technician?
