MCR-3 Microwave Chemical Reactor, 0 — 750W, Gongyi Yuhua Instrument Co., Ltd (CAT#: STEM-GME-0136-YJL)

MCR-3 Microwave Chemical Reactor, 0 — 750W, model MCR-3 is manufactured by Gongyi Yuhua Instrument Co., Ltd. In recent years, the development of microwave chemistry technology is in the ascendant, and the scientific community has paid great attention to the application of microwave energy in the field of extraction and synthesis. Due to the particularity of the heating effect, non-heating effect and induced catalytic effect of microwave, it has brought a great impact on the field of chemistry, especially the field of organic synthesis. Microwaves are used in organic synthesis reactions, and the reaction speed is 10-thousand times faster than conventional methods. And it can synthesize substances that are difficult to synthesize by conventional methods. So far, the studies that have been studied and achieved are: Diels-Alder cycloaddition reaction, rearrangement reaction, esterification reaction, Pekin reaction, alkylation, oxidation, substitution, condensation, addition and polymerization, etc. As a professional manufacturer of laboratory instruments, we have launched the MCR-3 microwave chemical reactor suitable for atmospheric synthesis and extraction according to the requirements of the majority of users.

(1) Non-pulsed microwave continuous heating
The research shows that the pulsed microwave will generate high-threshold electromagnetic pulses at the moment of "on" and "off", and the phenomenon of temperature overshoot or large oscillation will occur, and it is also easy to destroy the morphology of organic molecules, thus affecting the consistency of experimental results. The characteristics of non-pulse microwave continuous heating are: frequency conversion microwave power adjustment, microwave output is continuous output, no pulse stimulation.
(2) Microwave power frequency conversion control
Using dual CPU technology, auxiliary monitoring and control. The self-adaptive PID adjustment technology can overcome the occurrence of overshoot under the conditions of changes in ambient temperature, polarity of reacting substances, changes in heat capacity, and changes in mathematical models. Make the microwave adjust the microwave transmission power with the feedback of the temperature, so as to accurately reach the temperature setting value. Automatically adjust the power size and the intensity of the reaction to achieve the ideal control effect.
(3) Platinum resistance temperature control system
The shielded platinum resistance is directly inserted into the reactor to measure the internal temperature of the reaction, and the data is accurate. Reliable shielding effectively eliminates any electromagnetic interference and self-heating effects.
(4) Ten-level adjustment of microwave power
As we know microwave heating is fast and the reaction is violent. We divide the power into ten grades within the effective microwave power range, and the microwave power can be automatically controlled by frequency conversion within the power range limited by each grade, thereby limiting the intensity of the reaction and the speed of the reaction.
(5) Five-step temperature program
Through the control of the microcomputer, the temperature rise process of the reaction can be divided into five stages, and the user can edit various reaction parameters: reaction temperature, reaction time, and maximum power. And the microwave can also modify the reaction conditions without stopping during work.
(6) Large LCD screen
The effective pixels are 240×128, and the screen size is up to 120×80mm. The LCD screen displays synchronously: real-time working period, set power, set temperature, set time. Real-time power, real-time temperature, real-time time. By turning the page, the temperature curve can be displayed.
(7) At the same time, it is equipped with an inert gas inlet and a built-in magnetic stirrer. The stirring speed is infinitely adjustable.
