In fields such as chemical synthesis, pharmaceutical research and development, and material preparation,The 30l double-layer glass reactor has become the core equipment for laboratory and pilot production due to its transparency, precise temperature control, and corrosion resistance.Its unique double-layer structure and efficient working principle provide a stable and reliable environment for various chemical reactions.

　　1、 Structural composition: a precision designed "sandwich" system

The main body of a 30l double-layer glass reactor is composed of three parts: an outer protective structure, a middle jacket layer, and an inner reactor body

1. Inner reactor body: made of high borosilicate glass, directly carrying the reactants. Its transparent nature allows operators to observe the reaction process in real time, making it easy to adjust parameters in a timely manner; The precise calibration of the kettle volume is 30l, with smooth inner walls that are easy to clean and corrosion-resistant.

2. Intermediate jacket layer: It is a key structure that connects the outer and inner layers, forming a closed "heating/cooling chamber". By introducing high-temperature or low-temperature media into the jacket, precise temperature control of the inner reaction system can be achieved (temperature control accuracy ± 1 ℃). The jacket and the kettle body are sealed with flanges to ensure that there is no risk of medium leakage.

3. Outer protective structure: including stainless steel frame and protective cover, providing physical support (impact resistance, anti tipping) for the glass kettle body, while protecting the safety of operators; The top is equipped with a feeding port, a condensation reflux port (connected to a condensation tube for material recovery), a stirring port (equipped with a stirring blade), and a discharge valve at the bottom.

In addition, the device also integrates key components such as mixing system, temperature probe, vacuum interface, etc.

　　2、 Working principle: Collaborative logic of heat transfer and reaction control

The core function of a 30l double-layer glass reactor is to indirectly regulate the temperature of the inner reaction system through the circulation of the medium in the jacket layer

1. Heating mode: When the reaction needs to be heated up, heat transfer oil (or water) is introduced into the jacket layer, and the medium is heated to the target temperature (such as 80 ℃) through an electric heater (or external heat source). The high-temperature medium conducts heat to the inner kettle body through the jacket wall, gradually raising the material temperature to the required reaction conditions.

2. Cooling mode: If the reaction requires cooling, refrigerant is introduced into the jacket, and the low-temperature medium absorbs the heat of the inner kettle body, stabilizing the material temperature in the low-temperature range (such as 0 ℃).

3. Dynamic balance: The temperature probe provides real-time feedback on the inner layer temperature data, and the control system automatically adjusts the medium flow rate or heating/cooling power to ensure temperature fluctuations of ≤± 1 ℃, meeting the temperature sensitive response requirements.

The 30l double-layer glass reaction kettle achieves "thermal isolation+precise temperature control" through a double-layer structure, combined with transparent visibility and flexible interface design, becoming a crucial reaction tool from laboratory small-scale to pilot stage, providing a safe and efficient solution for scientific research and production.
