Teflon lined stainless autoclave is mainly composed of reaction vessel, agitator and transmission system, cooling device, safety device, heating furnace and so on. Among them, the tank body and cover are made of stainless steel processing, and the tank body wall is lined with polytetrafluoroethylene material to enhance its corrosion resistance and high temperature resistance. The agitator is usually driven by a servo motor through a coupling, which can realize stepless speed regulation to meet the needs of different reaction processes. The heating method is generally dry electric heating, but also can be made according to user requirements of electric heating heat conduction oil heating or jacket heating.

What reaction conditions require it?
Ptfe lined stainless steel autoclaves show their unique advantages under a variety of reaction conditions, especially in high temperatures, highly corrosive media, high pressure, the need to stir and the reaction environment has special requirements of the reaction, the following is a detailed description of these typical reaction conditions:
Polytetrafluoroethylene lining can withstand high temperature environments, ensuring that the autoclave can still operate normally under high temperature conditions.
In some chemical reactions, higher temperatures are needed to promote the reaction, such as synthesis reaction, pyrolysis reaction, etc. At this time, the high temperature resistance of PTFE lined stainless steel autoclave is particularly important.
Teflon is extremely resistant to corrosion and can resist the attack of most chemicals.
When the reaction medium is strong acid, strong alkali or other corrosive substances, the use of polytetrafluoroethylene lined autoclave can effectively protect the equipment from corrosion, while ensuring the safety and stability of the reaction.
The stainless steel housing provides sufficient strength and pressure tolerance for the autoclave.
In some high-pressure chemical reactions, a higher pressure is required to promote the reaction or to control the direction of the reaction. At this time, the high pressure bearing capacity of the PTFE lined stainless steel autoclave is particularly critical.
Teflon-lined stainless steel autoclaves are usually equipped with stirring devices to ensure that the reactants can be fully mixed and reacted during the reaction.
For reactions that require stirring, the use of such equipment ensures a uniform mixture of reactants, thereby improving reaction efficiency and product quality.
Some chemical reactions have special requirements for the reaction environment, such as the need for inert gas protection, the need to avoid metal ion pollution.
Teflon-lined stainless steel autoclaves can meet these special requirements, providing a stable and pure reaction environment for the reaction.

Purchase Guide
If you want to buy a good teflon lined stainless steel autoclave, there are some key factors that you must consider:
Application scenarios and requirements
Specify which specific chemical reactions or processes the autoclave will be used for.
Consider the properties of the reactants, such as corrosion, temperature range, pressure requirements, etc., to ensure that the selected autoclave liner and shell material can meet the requirements.
Material selection
Lining material: Polytetrafluoroethylene (PTFE) is a commonly used lining material, with excellent corrosion resistance and high temperature resistance. Make sure the autoclave is lined with a high quality PTFE material.
Shell material: Stainless steel is the commonly used material of autoclave shell, which has good structural strength and corrosion resistance. According to the specific needs, you can choose different types of stainless steel, such as 316L stainless steel.
Technical parameters
Working pressure and temperature: According to the reaction requirements, select the appropriate working pressure and temperature range. Ensure that the working pressure and temperature of the selected autoclave can meet the actual needs, and leave a certain safety margin.
Volume: Select the appropriate volume size according to the reaction scale. Too large a volume may result in uneven heating, while too small a volume may not meet the reaction needs.
Rate of heating and cooling: Consider the rate of heating and cooling required during the reaction to ensure that the autoclave selected can meet these requirements.
Sealing performance
Ensure that the autoclave is well sealed to prevent material leakage or outside air entry during the reaction.
Check the quality and installation of seals to ensure their long-term stable operation.
Safety performance
Consider the safety performance of the autoclave, such as the configuration of safety devices such as bursting film, pressure gauge and temperature sensor.
Ensure that the selected autoclave complies with the relevant safety standards and regulations to ensure safety during operation.
Brand and after-sales service
Choose well-known brands of autoclaves to ensure product quality and after-sales service are guaranteed.
Understand the supplier's after-sales service policy, such as warranty period, repair service, etc., in order to be able to solve problems in the process of use.
Price and cost performance
Under the premise of meeting all the above requirements, consider the price and cost performance of the autoclave.
Compare the prices and services of different suppliers and choose the most cost-effective products.
