A jacketed glass reactor is a device used for chemical reactions. It is made of high borosilicate glass and has a jacket structure on the outside, which is used to heat or cool the reactants in the reactor through a heat exchange medium (such as water, oil or steam). It has excellent chemical stability, high temperature resistance and transparency, making it widely used in laboratories and small-scale production. The design of the jacketed glass reactor allows users to accurately control the reaction temperature, observe the reaction process, and evenly mix the reactants through a stirrer to improve the reaction efficiency and effect.

Basic structure

The jacketed glass reactor is mainly composed of the following parts:

1. The reactor body: made of high borosilicate glass, which is resistant to high temperature, corrosion and chemical stability. The transparent design makes it easy to observe the internal reaction.
2. The jacket: heating or cooling through the heat exchange medium (such as water, oil) in the jacket to achieve precise temperature control
3. Agitator: installed in the reactor body, used to mix the reactants, common types include paddle type, frame type, spiral type, etc.
4. Temperature control system: including temperature sensors and controllers, used to monitor and adjust the temperature in the reactor.
5. Inlet and outlet: used to add reactants and discharge products, usually designed with multiple calibers and positions for different operation requirements.
6. Condenser: installed on the upper part of the reactor, used to condense the evaporated solvent and gas to avoid loss and pollution.
7. Sealing device: ensure the sealing inside the reactor to prevent leakage of reactants and external pollution.

            In summary, jacketed glass reactors have been widely used in scientific research, teaching and small-scale production due to their excellent material properties, precise temperature control, good stirring effect and safety. In addition to the above advantages, compared with reactors made of other materials (such as stainless steel and titanium), glass reactors are less expensive and are particularly suitable for use in laboratories and small-scale production. The chemical corrosion resistance and high temperature resistance of high borosilicate glass give it a long service life, reducing the frequency and cost of replacement, making it a very good laboratory equipment.
