Description
Technical Parameters
A Hydrothermal Autoclave 100 ml is an experimental equipment commonly used in chemical synthesis laboratories.Mainly composed of kettle body,heater,temperature controller,pressure controller,muffler,safety valve,temperature probe,etc.The kettle body is usually made of stainless steel and adopts a spherical design,which can withstand heavy pressure under high pressure.The heater is used to heat the solution inside the kettle,and the temperature controller and probe are used to monitor and adjust the temperature of the solution.The pressure controller is used to control the pressure inside the kettle and automatically release the safety valve when the pressure is too high to ensure the safety of the experiment.It is an efficient,safe,environmentally friendly,high-precision,and diverse experimental equipment commonly used in chemical synthesis laboratories.Its working principle is based on the changes in physical and chemical properties of solutions under high pressure and high temperature conditions,and precise temperature and pressure control is achieved using digital temperature control systems and pressure control systems.
Product Introduction
Hydrothermal autoclave is a high-temperature and high-pressure equipment used for materials science,chemical and biological research,as well as industrial production.The hydrothermal high-pressure kettle mainly consists of the kettle body,sealing device,heating device,pressure control system, etc.The kettle body usually has good resistance to high temperature and pressure.The sealing device includes a detachable PTFE lining to prevent damage to the components inside the sample and kettle body.Heating devices usually use electric heating wires or plates,which can heat the sample and water to a high-temperature and high-pressure state.The pressure control system includes a pressure gauge and a safety valve for monitoring and controlling the pressure inside the kettle.
When using a Hydrothermal Autoclave 100 Ml,the experimental sample needs to be carefully prepared and placed in a carefully designed PTFE lining inside the reactor along with an appropriate amount of water.Polytetrafluoroethylene material,with its excellent high temperature resistance and corrosion resistance,ensures the purity and safety of the sample and reaction medium during the experimental process,avoiding the influence of external pollution or lining materials on the experimental results.
Subsequently,carefully close the kettle lid and use a sealing device to ensure the airtightness of the environment inside the kettle,which is a key step in achieving high temperature and high pressure conditions.Once the sealing is completed,start the heating device and gradually heat the sample and water inside the kettle to the preset high temperature and high pressure state through the precisely controlled heating system.This process not only requires fast heating speed,but also precise temperature control to ensure consistency and reproducibility of experimental conditions.
In extreme environments of high temperature and pressure,the interaction between the sample and water is greatly accelerated,promoting the occurrence of various physical and chemical changes.These changes include but are not limited to:synthesis reactions of compounds,cracking or reforming of organic compounds,and phase transition or restructuring of inorganic materials.These processes have profound significance for understanding the evolution laws of matter in nature,developing new materials,and optimizing industrial production processes.
In order to comprehensively characterize and analyze these changes,researchers will use various technical means,such as optical microscopes to observe the morphological changes of samples and water,and precision instruments such as spectrometers and chromatographs to detect changes in their physical and chemical properties.Through these means,rich experimental data can be obtained,providing a solid foundation for subsequent mechanism exploration and theoretical model establishment.
The 100ml hydrothermal autoclave,as an advanced experimental equipment for simulating the geological environment inside the Earth,deeply embodies the basic principles of earth science in its working principle.It is not only an experimental tool,but also a bridge connecting laboratory research with natural phenomena.By simulating the high temperature and pressure conditions inside the Earth,hydrothermal high-pressure reactors provide a unique research platform for researchers in multiple fields such as materials science,chemistry,biology,and even geology,promoting in-depth exploration of basic scientific problems and facilitating the integration and innovation of interdisciplinary knowledge.

The working principle of a 100 milliliter hydrothermal autoclave is based on changes in physical and chemical properties under high pressure and high temperature conditions.During the experiment,the sample to be reacted is loaded into the kettle and an appropriate amount of solvent is added.Then, the heater starts working,heating the solution inside the kettle to the set temperature.Usually,the working temperature of the high-pressure kettle can reach over 200 degrees Celsius.At the same time,the pressure controller starts working and controls the pressure inside the kettle by adjusting the pressure valve,usually reaching a maximum of 20Mpa.
Under high temperatures and pressures,the physical and chemical properties of solutions undergo significant changes.The most significant one is that under high temperature and pressure conditions,the polarity and dielectric constant of the solvent change,which accelerates the reaction speed and improves the reaction efficiency.In addition,high temperature and high pressure conditions can also lead to a decrease in the gas diffusion rate in the solvent,which can accelerate the experimental reaction process and improve the accuracy of experimental results.
