3. Mixing device: The mixing device consists of a mixing motor and a stirring paddle, used to stir reactants and accelerate reaction speed. The speed of the mixing motor can be adjusted by the governor to meet the needs of different experiments. Stirring paddles are usually made of stainless steel or polytetrafluoroethylene materials, which can effectively prevent reactants from adhering to the blades. The stirring device is one of the important components of the reaction equipment, mainly used for stirring reactants and accelerating reaction speed.
3.1 Mixing motor
The stirring motor is the core component of the stirring device, which drives the stirring paddle through a gearbox for stirring. A 5-liter glass reactor usually uses an AC or DC motor, and the appropriate power and speed range are selected based on experimental requirements. AC motors are suitable for long-term continuous operation, while DC motors are suitable for frequent start stop work situations. The speed of the motor can be adjusted by the governor to meet the needs of different experiments.

The stirring paddle is a component that comes into direct contact with the reactant and stirs the reactant through rotation. A 5-liter glass reaction kettle generally uses a frame type stirring paddle or an anchor type stirring paddle, and appropriate shapes and sizes are selected according to experimental requirements. The box type stirring paddle is suitable for liquids with high viscosity or reactants that require large-scale stirring, while the anchor type stirring paddle is suitable for reactants that require strong stirring and high shear force. The material of the stirring paddle is usually stainless steel or polytetrafluoroethylene, which can resist chemical corrosion and wear.
3.3 Sealing device
The sealing device is an important component of the mixing device, and its function is to prevent the leakage of reactants during the mixing process. The 5l glass reaction kettle generally adopts mechanical or magnetic seals, and suitable types and specifications are selected according to experimental requirements. Mechanical seals are suitable for high temperature, high pressure, and high viscosity reaction environments, while magnetic seals are suitable for low viscosity, easy crystallization, and highly corrosive reaction environments. The materials used for sealing devices are usually wear-resistant and corrosion-resistant materials, such as graphite, ceramics, etc.
3.4 Control System
The control system is an important component of the mixing device, which can achieve control operations such as starting, stopping, and speed regulation of the motor. The 5-liter glass reaction kettle generally adopts a PLC or microcontroller control system, and suitable control methods and functions are selected according to experimental requirements. The control system can achieve automated control and data collection, as well as linkage control with other equipment to achieve the automation of the entire experimental process.

The heating ring is usually wrapped around the outside of the glass body, while the heating plate is placed at the bottom of the glass body. By adjusting the power of the heating coil and the temperature of the heating plate, the reaction temperature and reaction speed can be controlled.
5. Cooling device: The cooling device usually consists of a refrigerator and a cooling plate, used for cooling and temperature control. Refrigerators are usually embedded below the heating plate and reduce the reaction temperature through refrigerant circulation. The cooling plate is placed on top of the glass body to accelerate heat exchange and evenly cool down.
6. Pressure gauge: A pressure gauge is a device used to monitor the pressure inside the reactor in real-time. It is usually installed above the glass body and can display real-time pressure changes inside the reaction kettle. Pressure gauges have the characteristics of high accuracy and stability, which can detect abnormal situations in a timely manner and take corresponding measures.
6.1 Function of pressure gauge
The pressure gauge plays a very important role in a 5-liter glass reactor. It can display the pressure changes in the reactor in real-time, allowing the experimental personnel to understand the progress of the reaction. The function of a pressure gauge mainly includes the following aspects:
(1) Monitoring reaction pressure: During the chemical reaction process, the pressure inside the reactor will change. The monitoring function of the pressure gauge enables experimental personnel to timely understand this change and control the reaction process.
(2) Determine the endpoint of the reaction: By observing the changes in the pressure gauge, the experimenter can roughly determine whether the reaction has reached the endpoint. For example, in certain polymerization reactions, the pressure inside the reactor will gradually increase as the reaction progresses. When the pressure reaches a certain value, it indicates that the reaction has been completed.
(3) Prevention of safety accidents: The pressure gauge can provide alarm prompts for abnormal pressure changes, thereby effectively preventing the occurrence of safety accidents. For example, when the pressure inside the reactor suddenly increases, the pressure gauge will sound an alarm, reminding the experimental personnel to take corresponding measures to avoid accidents.
6.2 Composition of pressure gauge
The pressure gauge of a 5-liter glass reactor mainly consists of the following parts:
(1) Dial: The core component of a pressure gauge, used to display the pressure value. The dial is usually marked with pressure units and scale lines, making it convenient for experimental personnel to read the pressure value.
(2) Sensor: used to sense the pressure changes inside the reaction kettle and convert them into electrical signals for transmission to the dial. The accuracy and stability of sensors directly affect the measurement accuracy of pressure gauges.
(3) Connecting pipe: used to connect the pipeline between the pressure gauge and the main body of the reactor, thereby achieving real-time monitoring of the pressure inside the reactor. The connecting pipe should have sealing and pressure resistance to ensure the accuracy of the measurement results.
(4) Protective cover: used to protect the pressure gauge from external interference and damage. The protective cover is usually made of transparent material, making it convenient for experimental personnel to observe the pressure value on the dial.
6.3 Working principle of pressure gauge
The working principle of the pressure gauge for a 5-liter glass reactor is based on the elastic deformation of the elastic element to achieve pressure measurement. When the pressure inside the reactor acts on the elastic components of the sensor, the elastic components will deform, which in turn drives changes in the electrical signal inside the sensor. This electrical signal is processed and transmitted to the dial, ultimately displaying the pressure value inside the reactor.
6.4 Precautions for use and maintenance
In order to ensure the normal operation and extended service life of the pressure gauge of the 5-liter glass reactor, it is necessary to pay attention to the following items and carry out regular maintenance:
(1) Regular calibration: Pressure gauges should be calibrated regularly during use to ensure the accuracy of measurement results. During the calibration process, a high-precision standard pressure gauge should be used as a reference and errors should be corrected.
(2) Shockproof and anti drop: During use, the pressure gauge should be avoided from vibration and falling to avoid affecting its normal operation and service life.
(3) Keep clean: The dial and sensor parts of the pressure gauge should be kept clean to avoid the influence of oil and dust. During use, the dial and sensor surface should be regularly wiped with a clean soft cloth.
(4) Check the connecting pipe: Regularly check whether the connecting pipe is securely connected and whether there is any air leakage. If any looseness or damage is found in the connecting pipe, it should be dealt with promptly.
(5) Replace sensor: If a sensor is found to be faulty or damaged, it should be replaced in a timely manner. When replacing a sensor, attention should be paid to selecting a sensor with the same model as the original sensor to ensure the accuracy of the measurement results.
