Hydrothermal Autoclave 100 Ml

100 ml hydrothermal autoclave, also known as hydrothermal synthesis reactor, high-pressure digestion tank, pressure lysis bomb, etc., is a closed container that can decompose insoluble substances. It uses the high temperature and high pressure environment in the tank to promote the chemical reaction, especially suitable for synthetic reactions and material preparation requiring high temperature and high pressure conditions. Its working principle is that under certain temperature and pressure conditions, the use of high temperature and high pressure aqueous solution as the reaction medium, so that those insoluble or insoluble substances under atmospheric conditions dissolve or react to produce dissolved products. By controlling the temperature difference of the solution, convection is generated to form a supersaturated state, which can precipitate the growth crystal or synthesize the target product.
Material characteristics of the kettle body
Stainless steel material
Corrosion resistance
Stainless steel has excellent corrosion resistance and can resist the erosion of various acids, alkalis, salts and other chemical substances. In the use of hydrothermal autoclave process, the reaction system may involve a variety of corrosive media, stainless steel material can effectively protect the kettle body from corrosion, extend the service life of the equipment.
High temperature and high pressure resistance
Stainless steel has a high melting point and strength, can withstand high temperature and high pressure working environment. Hydrothermal autoclaves usually need to react under high temperature and high pressure conditions, and stainless steel can meet this requirement to ensure the smooth progress of the experiment.
Non-magnetic
Some stainless steel materials (such as 316L) have non-magnetic characteristics, which is particularly important in some specific experiments. For example, in experiments requiring accurate measurement of magnetic fields or magnetic material research, non-magnetic stainless steel can avoid interference with the experiment and ensure the accuracy of the experimental results.
Easy processing and welding
Stainless steel is easy to process into a variety of shapes and sizes, and good welding performance. This makes the manufacturing process of hydrothermal autoclaves easier and enables different sizes and shapes of equipment to be customized as required.
Other optional materials

Titanium alloy
In some special cases, such as the need for higher corrosion resistance and high temperature resistance, titanium alloy can be selected as the body material. Titanium alloys have excellent corrosion resistance and high temperature resistance, but the cost is relatively high.
Hastelloy
Hastelloy is a nickel-based corrosion resistant alloy with good corrosion resistance, high temperature resistance and oxidation resistance. Hastelloy alloy may be a good choice in some extreme conditions, such as high temperature and pressure reactions containing strong corrosive media. But again, the costs are relatively high.

Liner material characteristics
Polytetrafluoroethylene (PTFE)
Excellent corrosion resistance: PTFE has excellent corrosion resistance to almost all chemical substances, and can resist the erosion of strong corrosive media such as strong acid, strong alkali and aqua regia. This makes PTFE inner tank one of the most commonly used inner tank materials in hydrothermal autoclaves.
Good sealing: PTFE has a low coefficient of friction and good self-lubrication, which makes the seal between the inner tank and the tank body tighter. In the hydrothermal autoclave, good sealing is the key to ensure the safety of the experiment and the accuracy of the experimental results.
High temperature resistance: PTFE has a wide temperature range and can usually be used in the range of -196℃ to +250℃. This temperature range covers most experimental requirements for hydrothermal autoclaves.
Non-toxic and physiologically inert: PTFE material is non-toxic, odorless, tasteless, and physiologically inert, and will not react with experimental substances. This makes PTFE liners ideal for handling biological samples or for experiments where contamination needs to be avoided.
Modified polytetrafluoroethylene (e.g. TFM)
Higher temperature resistance: Compared with PTFE, modified polytetrafluoroethylene (such as TFM) has higher temperature resistance. Its use temperature range can usually be extended to -200 ° C to +260 ° C or higher, suitable for higher temperature experimental needs.
Better pressure resistance: Modified PTFE materials generally have better pressure resistance and are able to withstand higher pressures without deformation or rupture. This is especially important for experiments that need to be performed under high pressure conditions.
Good processing performance: Modified polytetrafluoroethylene materials are also easy to process into various shapes and sizes, which is easy to manufacture complex structures.
Para-polystyrene (PPL)
Excellent corrosion resistance: PPL materials also have excellent corrosion resistance and can resist the erosion of a variety of acids, alkalis, salts and other chemicals. In some specific experiments, PPL liners may be a more suitable choice than PTFE.
Good high temperature resistance: PPL materials also have a wide temperature range and can usually be used under high temperature conditions without performance degradation.
Good mechanical properties: PPL materials have good mechanical properties, such as high strength and hardness. This allows the PPL liner to withstand higher pressure and impact loads.
Sealing material characteristics
Seal material

Fluorine rubber
Fluorine rubber is a commonly used sealing ring material, with excellent corrosion resistance, high temperature resistance and oil resistance. In the hydrothermal autoclave, the fluorine rubber sealing ring can effectively prevent the leakage of the medium and ensure the safety and accuracy of the experiment.

Polytetrafluoroethylene (PTFE)
In addition to being an inner liner material, PTFE can also be used to make sealing rings. PTFE sealing ring also has excellent corrosion resistance and high temperature resistance, and low friction coefficient, good self-lubrication, can achieve a tighter seal effect.

Other materials
According to the different experimental requirements and equipment specifications, you can also choose other materials of sealing rings, such as nitrile rubber, silicone and so on. These materials have their own characteristics and can be selected according to the actual situation.
Seal structure characteristics
Circular mortise seal
Circular mortise seal is a commonly used sealing structure, through the precise fit and appropriate tightening force to achieve the sealing effect. The sealing structure has the advantages of simple structure, easy processing and maintenance.
Cone phase contact seal
Cone phase contact seal is another commonly used sealing structure, through the tight fit of the cone to achieve the sealing effect. The sealing structure has the advantages of good sealing performance and can withstand high pressure.
Other sealing structures
According to different equipment specifications and experimental needs, other types of sealing structures can also be selected, such as O-ring seals, metal seals, etc. These sealing structures have their own characteristics and can be selected according to the actual situation.
Other material characteristics
Heating element material

Electric heating wire
Electric heating wire is a commonly used heating element material, with the advantages of fast heating speed and accurate temperature control. In a hydrothermal autoclave, the electric heating wire is usually wrapped around the outside or inside of the kettle body (such as the bottom of the inner tank) for heating.
Other heating elements
In addition to the heating wire, you can also choose other types of heating elements for heating, such as oil bath heating, sand bath heating, etc. These heating elements have their own characteristics and can be selected according to experimental requirements and equipment specifications.

Other auxiliary materials
Thermal insulation materials
In order to keep the temperature inside the tank body stable and reduce energy loss, hydrothermal autoclaves are usually equipped with thermal insulation materials. These thermal insulation materials have good thermal insulation performance and can effectively maintain the temperature inside the kettle body.
Support and fixing materials
In order to ensure the stability and safety of the hydrothermal autoclave during use, it is also necessary to use support and fixing materials to fix and support the equipment. These materials usually have good mechanical properties and corrosion resistance.
