Details and Specification

The Hydrothermal Autoclave Reactor use to carry hydrothermal reaction at high pressure and high temperature. Hydrothermal synthesis reactor generally comes in a two variety; the first is Polytetrafluoroethylene (PTFE) or Teflon lined hydrothermal autoclave reactors and the second is PPL lined autoclave. Hydrothermal reactor mainly made up of two parts; outer high-quality stainless steel jacket and inner Teflon liner or Teflon chamber. In the Teflon-lined autoclave, the reaction is carried out at maximum 240-degree Celsius (428 Fahrenheit), while the safe temperature is 200-degree Celsius (392 Fahrenheit). PPL lined reactor use for the reaction operate at higher temperature, where the safe temperature will be 260-degree Celsius (500 Fahrenheit) and the maximum operating temperature is 280-degree Celsius (536 Fahrenheit). This product extensively used in the scientific laboratory, research and development labs, institutional organizations, quality analysis section in industries etc.

Development PPL Lined Hydrothermal Autoclave

Techinstro developed and supply two type of sealing for the tightening of a reactor vessel. The screw type sealing has been given to the reactor with capacity 10ml, 25ml, 50ml, 100ml, 150ml, 200ml, 250ml, 300ml, 400ml, and 500ml, while the flange type sealing will be in a 1000ml, 1500ml, and 2000ml autoclave. We used the double coated Teflon vessel for better performance. The autoclave has been designed to use for external heating where the reactor can be heated in the oven, furnace or self-heating. The ideal heating and cooling temperature rate to get better results will be 5 0C.

The Teflon-lined hydrothermal synthesis autoclave is corrosive resistant. It is also acidic and alkaline resistant hence used for highly alkaline and acidic solutions. The autoclave for hydrothermal synthesis mostly used for crystallization processes and nanoparticles. Since it is operating at a very high temperature and high pressure, hence it is also called as the hydrothermal bomb. Hydrothermal laboratory reactor available with a pressure gauge to maintain appropriate pressure condition required for the chemical reaction. It also comes with features of self-heating with all heating arrangement.

Design PPL Lined Hydrothermal Autoclave

Hydrothermal Autoclave Reactor manufactured by Techinstro are elegantly designed, and are easy to operate; made from high-quality stainless steel structures that guarantee durability, come with gas-tight/air-tight with PTFE inner chamber that reduces corrosion, which is also excellent acid resistance and alkali resistance. Its external heating feature reduces the volume and ensures a favorable reaction in the same reactor operating temperature

The new feature of self-sealing closures is made from durable, reliable cable seal structure, which ensures long-term stability and prevents seeping problem or leakage.

Our aim has been to offer our customers top quality high-pressure Hydrothermal Autoclave Reactor, customized for each application and technically supported by highly competent and skilled staff. Contact us with specifications, and we shall help you to configure a system that will suit your requirement and make one for you!

  • Place the Autoclave and sterilizing material on the table or on the shelf.
  • Twist the screw type threaded primary SS cap (SS Alloy 304) in an anticlockwise direction until it has been opened.
  • There is 2 type of SS gasket/lid in the reactor, 1 is on the bottom side and another is on top of the Teflon vessel chamber.
  • Lift the top SS gasket or lid and take-out milky white colorPTFE/Teflon reaction chamber.
  • Now fill solvent (as per liner’s capacity) in the reaction chamber and sealed it.
  • Make sure that the Teflon cap should be air-tight to avoid pressure leakage.
  • Place Teflon or PTFE liner in a stainless steel chamber.
  • Keep top gasket over the vessel and make sure that the Teflon-lined vessel placed properly inthe Stainless Steel chamber.
  • Then twist primary SS cap in a clockwise direction until it does not turn anymore.
  • The secondary SS cap has been given at the top of the primary cap for extra tightening to avoid pressure leakages.
  • Rotate primarySS cap in the clockwise direction with the help of locking rod for additional tightening.
  • Placed the hydrothermal autoclave in oven or furnace and heat it till reactor’s safe temperature.
  • Increase the temperature of the oven and set heating rate5 0C/minute only.
  • A researcher can heat the hydrothermal autoclave till 200 0C for safe use.
  • After completion of the hydrothermal synthesis reaction, the autoclave’s cooling rate will be 5 0C/minute.
  • Make sure that, after completion of the process clean PTFEor Teflonliner properly for reuse.
