High pressure hydrothermal reactor- LAB TOOL | CYKY

High Pressure Hydrothermal Reactor is an ideal tool for preparing advanced material by the hydrothermal method, especially heat treat sample under high oxygen pressure.

RC-Ni is reactor made of Ni-Base Superalloy, which has excellent creep strength and anti-oxidation. It can reach 1100 °C with a pressure up to 4Mpa under oxygen or inert gas. A solenoid valve is installed on the flange allows auto-pressure relief control. Temp. Control and Pressure Real-time Monitoring controller is separately installed


High Pressure Hydrothermal Reactor Technical parameters:


Warning: For your safety, the high-pressure vessel and furnace must be placed inside an explosive-proof box or case during using under high pressure. Never face on top flange without protection to avoid the accident.

Working Voltage

AC 208~240V, Single Phase, 2 KW,

Pressure Vessel

  • Made of Ni-Based Superalloy, optional at 65&100ml Air cold flange via aluminum heat radiator.
  • Liner inside vessel with various materials is available upon request at extra cost.
  • Attention: Processing Tube is consumable part, you can order replacement or spare one. It is user responsibility to choose suitable liner to grow different material.
  • A small quartz or Alumina boat should be used to load the sample inside the vessel. Please order separately. Never place the sample directly onto the vessel without a crucible. Vessel service-life could be reduced significantly if you do so.

Reactor Capacity & Dimensions

55 mm OD x 20 mm ID x 214 mm height, 65 mL capacity

65mm OD x 25mm ID x 210 mm height, 100 mL capacity

Working Temperature & Control

  • RT – 1100℃ Max.
  • Digital temperature controller with 30 segment programmable
  • Temperature accuracy +/- 1℃
  • Recommend heating rate <=10°C/min


3mm OD K Type with high-temperature tolerance (220℃) connector

Working Pressure

· 36 Mpa (5292 PSI)     Max  at 500°C

· 24 Mpa (3528 PSI)     Max. at 800 °C

· 14 Mpa (2116 PSI)     Max. at 900 °C

· 7 Mpa   (1058 PSI)    Max. at 1000 °C

· 4 Mpa   (588 PSI)     Max. at 1100°C

Pressure Sensor

Precision high-pressure sensor (measurement Range up to 250 bars) installed on the pressure vessel.

Pressure Relief Solenoid Valve

A default 15Mpa max. pressure relief solenoid valve is installed. When the pressure reaches the alarm set point (Max.15Mpa), the pressure inside the vessel will be released via the solenoid valve installed on the flange. For Max. pressure >15 Mpa, please shut off the manual needle valve nearby the solenoid valve.)

PC Control (optional)

A control software is available for controlling and displaying temperature and pressure by PC

  • The PC control module is compatible with Labview software.
  • Pressure & Temp. Real-Time Monitoring.


  • SS316 needle valve with 1/4 pipe connector & Pressure gauge included
  • Two copper gasket of 48mm diameter are included, which is consumables
  • Optional torque wrench is available to avoid overtightening the flange bolts. Please email us to learn the suitable tightening torque for the Hydrothermal Reactor.


One year limited warranty. Consumable parts such as copper gaskets, pressure vessels (if over-pressurized, over-heated or chemical interactions), and heating elements (if overheated) are not covered by the warranty.

Application Notes:

· The recommended temperature heating/cooling rate is 5~10 ºC/min

· DO NOT over tighten the flange screws as this may cause permanent damage to the flange or screws. Please refer to the instruction about proper torque for installing CF flange bolts. We recommend you to use a torque wrench to tighten the screws with the flange

· DO NOT use the pressure relief solenoid valve.to vent the vessel! It could contaminate the valve and impact its service life. Always use the manual pressure relief valve for venting

Warning:   For your safety,  the high-pressure vessel must be placed inside an explosive-proof box or case during using under high pressure.  Never face on top flange without protection to avoid the accident.
