How Does A Glass Reactor Work

Glass reactor is a kind of chemical reaction container commonly used in laboratory. It is usually made of glass, and its interior is smooth and easy to clean, without any pollution to the reaction products. Glass lab reactors are often used in experiments such as solution mixing, chemical reaction, distillation and extraction.

The working principle of glass reactor mainly depends on the external heating system and stirring system.

• Heating System: The glass reaction kettle is usually equipped with a heater or a heating water bath, through which the temperature of the liquid in the kettle is raised to accelerate the reaction rate. In the heating process, it is necessary to control the heating speed and temperature to avoid too high or too low temperature, which will affect the reaction effect.
• Stirring System: The stirring system of glass kettle is usually composed of motor, rotor, stirring blades and other parts, and the motor drives the stirring device to start stirring. The purpose of stirring is to fully mix the reactants and promote the reaction.

The Types of Glass Reactors

1. Standard Reactor: The standard reactor is the most common type, which usually consists of glass container, heating system and stirring system. It is characterized by simple structure and convenient operation, and is suitable for solution mixing, reaction, distillation and other operations in various chemical laboratories.

2. Glass Reaction Kettle with Condenser: The glass reaction kettle with condenser is added with a condenser part on the basis of the standard type, which is used to collect the gas or volatiles generated in the reaction process and condense them into liquid. This type of reactor is suitable for experiments that need to collect and separate gases or volatiles, such as synthesis of organic matter, extraction and so on.

3. Glass kettle with Separating Funnel: This reactor is added to the standard one to separate two immiscible liquids. This reactor is suitable for experiments requiring liquid-liquid extraction or separation, such as extraction and phase transfer catalysis.

4. Reactor with Filtering Device: The glass reaction kettle with filtering device is provided with a filtering device on the kettle cover for filtering solid particles or precipitates in reactants. This type of reactor is suitable for experiments that need solid-liquid separation, such as crystal growth and solid catalytic reaction.

5. Reaction with Pressure System: It adds a pressure system on the basis of the standard one, which can control the pressure inside the reaction kettle within a certain range. This kind of reactor is suitable for experiments that need high-temperature and high-pressure reactions, such as hydrogenation reaction and high-pressure synthesis.

6. With Lifting and Rotating Kettle Body: This type of glass reaction kettle can be lifted or lowered by lifting device to meet different height requirements. The lifting function makes it convenient for operators to feed, sample or clean the reaction kettle, and it is also convenient to adjust the height matching between the reaction kettle and other equipment. The rotatable characteristics of the kettle body enable the reaction kettle to rotate during operation, which increases the mixing degree of reactants and the reaction effect to a certain extent. The rotating function is suitable for experiments that need to be fully stirred, such as solution mixing and chemical reaction. This glass reactor is widely used in laboratories and production processes in the fields of chemistry, pharmacy, food and chemical industry. For example, it is used in organic synthesis reaction, catalytic reaction, catalyst preparation, extraction, distillation, crystallization and so on. This type of reaction kettle can be equipped with different types and capacities according to different experimental requirements, and the lifting and rotation can be adjusted according to experimental parameters.

How to Use

• Preparation: Check the state of the reaction kettle to ensure that the kettle body is intact and there is no air leakage. Prepare the required experimental articles and reagents, and measure and weigh them according to the experimental requirements.
• Installation of reaction kettle: Place the reaction kettle on a stable bracket or heating device to ensure firm installation. Connect external equipment such as power supply, cooler and agitator as required.
• Adding reagents: Open the reaction kettle and slowly and evenly pour the pre-weighed reagents into the kettle. Pay attention to avoid violent reaction or spillage.
• Heating or cooling: According to the experimental requirements, adjust the heating device or cooling device to control the temperature in the reaction kettle. When heating, the temperature should be gradually increased to avoid adverse reactions caused by drastic temperature changes.
• Stirring reaction: Start the stirrer and carry out the mixing reaction at an appropriate speed and time. Ensure that the stirrer can evenly stir the reactants and promote the reaction.
• Pay attention to safety: During the whole experiment, pay attention to safe operation. Wear experimental gloves, goggles and other personal protective equipment to avoid contact with toxic or corrosive substances. Pay attention to safety issues such as fire prevention and explosion prevention.
• End of experiment: After the experiment is completed, turn off the heating or cooling device and stop the operation of the agitator. According to the experimental requirements, the reaction products were taken out of the glass reactor for further treatment and analysis.
• Cleaning and maintenance: After the experiment, thoroughly clean and maintain the reactor to keep it in good condition and prolong its service life.
