Reactors for high pressure

Instruflow manufactures a wide range of high pressure reactors and autoclaves for a variety of applications. These stirred reactor systems have a profound significance in research and development applications where high temperature and high pressure is a prerequisite for effecting or enhancing a reaction process.

Salient features of these pressure reactors are as follows:

  1. • 50 ml to 100 liters volume reactors
  2. • Pressures upto 350 bar & temperatures upto 500째C
  3. • Available in different Material of Constructions (MOC) like SS-316, SS-316L, Hastelloy B/C, Monel, Nickel, Inconel, Titanium, Tantalum lined, Zirconium
  4. • High torque zero leakage magnetic drive coupling
  5. • IECEx / CE / ASME U stamp certified systems on request
  6. • Fully automated PC controlled high pressure system / pilot plant to continuously monitor, control & record various parameters like temperature, pressure, motor speed, gas / liquid flow, level, torque etc.


These reactor systems are used for the following purposes:

  1. • Used for high-pressure high-temperature chemical reactions like alkylation, amination, acetylation, acylation, bromination, carboxylation, catalytic reduction, chlorination, dehydrogenation, esterification, ethoxylation, halogenation, hydrogenation, methylation, nitration, oxidation, ozonization, polymerization, sulphonation etc.
  2. • To invent new molecules / chemicals & study reaction parameters
  3. • To produce chemicals in small quantity
  4. • For organic synthesis
  5. • For quality control & process improvements
  6. • For high throughput catalyst screening
  7. • For reaction calorimetry to study heat of reaction
  8. • For static, dynamic, loop & electrochemical HPHT corrosion testing
  9. • Gas hydrate formation study
  10. • In R&D centers, pilot plants & manufacturing facilities of fine & speciality chemicals, bulk drug (API) pharmaceuticals, dyes, intermediates, paints, oils, agrochemical, petrochemicals, oil & gas etc. Industries & in chemical engineering colleges / research institutes / defence organisations where high pressure reactions / testing is carried out.
