oneHydrothermal synthesis reactorIntroduction to High Pressure Digestion Tank:

Hydrothermal synthesis reaction kettle, also known as polymerization reaction kettle, includes high-pressure digestion tank, high-pressure tank, reaction kettle, pressure dissolution bomb, digestion tank, hydrothermal synthesis kettle, and experimental reaction kettle.

A hydrothermal synthesis reactor is a closed container capable of decomposing insoluble substances. Can be used for sample pretreatment in atomic absorption spectroscopy and plasma emission analysis; It can also be used for low-dose synthetic reactions; The purpose of rapidly dissolving insoluble substances can also be achieved by using a sealed environment with strong acid or alkali inside the tank and high temperature and high pressure. Sample pretreatment is performed in chemical analysis methods such as gas phase, liquid phase, plasma chromatography-mass spectrometry, atomic absorption, and atomic fluorescence. It is a powerful assistant for the determination of trace elements and the digestion of samples during trace element analysis. It can be applied in the determination of heavy metals such as lead, copper, cadmium, zinc, calcium, manganese, iron, mercury, etc. It can also be used as a high-temperature, high-pressure, corrosion-resistant, high-purity reaction vessel, as well as in organic synthesis, hydrothermal synthesis, crystal growth, or sample digestion and extraction. Dissolve heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, organic matter, etc. before sample preparation. Therefore, it is widely used in research and production in departments such as petrochemicals, biomedicine, materials science, geochemistry, environmental science, food science, and commodity inspection.

Characteristics of the Two Water Thermal Synthesis Reactor (High Pressure Digestion Tank):

1. Good corrosion resistance, no harmful substances overflow, reduced pollution, and safe use.

2. After heating and boosting, it can quickly and non destructively dissolve samples that are difficult to dissolve under conventional conditions and samples containing volatile elements.

3. Beautiful appearance, reasonable structure, simple operation, shortened analysis time, and reliable data.

4. There is a polytetrafluoroethylene lining inside, which provides care and is resistant to acid, alkali, and other substances.

5. Can replace platinum crucibles to solve the problem of sample dissolution for trace element analysis in high-purity alumina. The high-pressure digestion tank used in the oven, also known as the dissolution apparatus, pressure dissolution bomb, hydrothermal synthesis reactor, digestion tank, or polytetrafluoroethylene high-pressure tank, is a device that utilizes a strong acid or strong alkali and a high-temperature, high-pressure, and sealed environment inside the tank to achieve rapid digestion of insoluble substances. It is a powerful assistant for the determination of trace elements and the digestion of samples during trace element analysis. Sample pretreatment for digestion of heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, organic matter, etc.

Operation method of the three water thermal synthesis reactor (high-pressure digestion tank):

Pour the reactants into a PTFE liner or PPL liner and ensure that the feeding coefficient is less than 0.8.

Ensure that the position of the gasket under the kettle body is correct (with the protrusion facing downwards), then place the PTFE liner or PPL liner and upper gasket, tighten the kettle cover first, and then use screws to tighten the kettle cover until it is tight.

Place the hydrothermal synthesis reactor in the heater and heat it up to the desired reaction temperature at the specified heating rate. (Below the specified safe operating temperature).

After confirming that the temperature inside the abdomen is lower than the boiling point of the reactant solvent, the kettle lid can be opened for subsequent operations. When the reaction is completed and cooled down, it is also necessary to strictly follow the prescribed cooling rate for safety and the service life of the reaction kettle.

After confirming that the temperature inside the abdomen is lower than the boiling point of the reactant solvent, first use a screw to unscrew the kettle cover, and then open the kettle cover.

The hydrothermal synthesis reactor should be cleaned promptly after each use to prevent rusting. Special attention should be paid to cleaning the sealing parts of the kettle body and kettle cover line, and strict precautions should be taken to prevent them from being damaged or bumped.
