Reactor Technology


High-pressure reactor

Reference/Case Study:

The high-pressure reactors of the BR-25 and the BR-40 series are equipped with a valve, rupture disc and manometer as standard. Individual configurations and the use of PTFE inserts are possible at any time. The reactor lid fits to all vessel options. The low weight of the BR-25 and BR-40 reactors is the basis for a flexible use within the laboratory.

Range of Applications


  • Various kinds of synthesis like hydrogenation of C-C triple bonds, synthesis of metal nanoparticles, solvothermal synthesis and drug synthesis

Product Description

The high-pressure reactors BR-25 and BR-40 show off their strengths at minimum quantities approaches within organic matters or when working with fine chemicals. According to the customers’ needs, the reactors are made of stainless steel 316 Ti (1.4571) or hastelloy C-22 (2.4602). There are four vessel options available: the two standard vessels for BR-25 and BR-40, as well as the vessels for the use of PTFE inserts.

The high-pressure reactors BR-25 and BR-40 have several armatures:

  • Rupture disc, dip tube and valve are standard equipment
  • Pressure measurement is operated analog and/or digital
  • Two of the six ports are free for individual use. The connection type is a 1/8” tube connection. The number of free ports can be enlarged by the use of T-connections.

Stirring is possible for the BR-25 and BR-40 reactors by using magnetic stirring rods. In combination with the easy to use heating system, that does not need any programming, a user-friendly handling can be guaranteed. The compact size and the rather low weight of the reactors allow an easy transport, so that the reactors can be used in any place within the laboratory.

BR-25 and BR-40 have a wide range of applications. Often, they are used e.g. for different types of synthesis, like hydrogenation of C-C triple bonds or synthesis of metal nanoparticles.
