Products Introduction
There are many types of high pressure stirred lab autoclaves, and the common types include the following four types.
► Magnetic stirring high-pressure reactor
It is a high-pressure reaction equipment that uses a magnetic stirring device. Its unique design principles and structural characteristics make it widely used in laboratory high-pressure reactions.
Design principles and structural characteristics:
The design principle of magnetic stirring high-pressure vessel is based on magnetic coupling transmission technology. It rotates the stirrer inside the container (usually made of magnetic materials such as neodymium iron boron) under the action of a magnetic field by placing a magnetic field and a movable magnet outside the container. This design avoids the physical interference of the stirring shaft in traditional mechanical stirring devices on the reaction system, such as friction, wear, and leakage. At the same time, due to the absence of a stirring shaft penetrating the container, magnetic stirring high-pressure reactors are more likely to achieve high-pressure sealing, thereby ensuring the safety and stability of the reaction system.
Application scenarios:
It are widely used in reaction systems that require high sealing and no physical interference. For example, in high-pressure catalytic reactions, a magnetic stirring autoclave can provide a stable reaction environment and efficient stirring effect, thereby improving the activity and selectivity of the catalyst. In organic synthesis, It can be used to synthesize complex organic molecules such as polymer compounds and drug intermediates. In addition, it have broad application prospects in fields such as materials science and environmental engineering.
► Suspended mixing kettle
A suspended stirred tank is a high-pressure reaction equipment that uses an adjustable suspension system to suspend the agitator inside the container. Its unique design enables it to adapt to the stirring requirements of different reaction systems.
Design principles and structural characteristics:
The design principle of a suspended stirred tank is based on the combination of suspension technology and stirring technology. It suspends the mixer inside the container through an adjustable suspension system (such as springs, air cushions, etc.) and allows it to move freely inside the container. This design allows the stirrer to adjust the stirring speed and method according to the reaction needs, achieving high-speed or low-speed stirring. At the same time, the suspended stirred tank also has good sealing performance and pressure bearing capacity, which can meet the needs of high-pressure reactions.
Application scenarios:
Suspended stirred tanks are suitable for reaction systems that require flexible adjustment of stirring speed and method. For example, in the mixing of viscous materials, a suspended stirred tank can adapt to materials of different viscosities by adjusting the stirring speed and method of the agitator, thereby achieving efficient mixing and dispersion. In solid-liquid reactions, suspended stirred tanks can effectively disperse solid particles in the liquid, improving reaction efficiency and product quality. In addition, suspended stirred tanks are widely used in various reactions that require mixing, dispersion, dissolution, and other processes in industries such as chemical, pharmaceutical, and food.
► Spiral Stirring Reactor
It is a high-pressure reaction equipment that uses a spiral shaped stirrer for mixing. Its unique design makes it particularly suitable for mixing and dispersing viscous materials.
Design principles and structural characteristics:

Product Features
The laboratory stirred autoclave realizes the uniform mixing of materials in the following ways:
◆ Fluidity of mixed materials: Determining the fluidity of reaction materials is the key to achieve uniform mixing. If the materials have enough fluidity, the mixer can mix them together better. If the material is sticky or sticky, its fluidity can be changed by controlling the temperature, adding solvents or softeners, etc., so as to achieve better mixing.
◆ Control of stirring parameters: The stirring parameters of a stirred autoclave, such as stirring speed, stirring time and stirring mode, are very important for achieving uniform mixing of materials. Proper mixing speed and time can ensure sufficient mixing effect and prevent materials from caking or deterioration due to excessive mixing. Different materials and reaction types may require different stirring conditions, so they need to be optimized according to specific conditions.
◆ Reverse stirring or inversion: In some cases, especially in the case of liquid-solid reaction or gas reaction, reverse stirring or inversion operation can be considered to improve the mixing effect. This operation mode can change the flow mode of materials and promote the uniform mixing of reaction materials.
◆ Adding additives or dispersants: For some materials that are difficult to mix, additives or dispersants can be added to promote the mixing process. Additives or dispersants can improve the fluidity of materials, reduce the viscosity and reduce the agglomeration between particles, so as to achieve better mixing effect.
Applications

◆ High pressure stirred lab autoclaves: It can be used to produce vitamins, and the specific production process may be different for different vitamins.
◆ Preparation of synthetic precursors: According to the types of vitamins to be synthesized, prepare corresponding precursor substances, such as amino acids, sugars, fats, etc.
◆ Synthesis reaction: The precursor is added into the laboratory stirred autoclave, the catalyst and other necessary reagents are added, the lid of the autoclave is closed and heated to a high pressure state. Under high pressure, catalysts and other reagents promote the chemical reaction of precursor substances to produce crude vitamins.
Knowledge
The common types of pressure sensors in high pressure stirred lab autoclaves are as follows:
Strain Gauge Sensor
This is one of the most common types of pressure sensors. It uses a strain gauge made of metal or semiconductor material to measure the strain caused by stress. When pressure is applied to the strain gauge, its resistance value will change, so the pressure value can be determined by measuring the change of resistance value.
Capacitive Sensor
This sensor uses the principle of capacitance to measure pressure. It contains two electrodes, and when pressure is applied to the distance between the electrodes, the capacitance value will change. By measuring the change of capacitance, the pressure value can be calculated.
Magnetic Sensor
A magnetic sensor measures pressure by the change of magnetic field. It consists of a spring and a permanent magnet. When pressure is applied to the spring, it will change the magnetic field distribution between the permanent magnet and the sensor, so that the pressure value can be determined by measuring the magnetic field change.
Piezoelectrical sensor
Piezoelectric Sensor use piezoelectric materials, such as crystals or ceramics, to measure pressure. When pressure is applied to piezoelectric materials, it will cause them to generate charge or voltage signals. The pressure value can be determined by measuring the change of charge or voltage signal.
