Pressure Reactor 15 bar
A reactor for low-pressure reactions (e.g. hydrogenation, carbonylation & hydrolysis).
The Pressure Reactor 15 bar is mainly designed for joint use with the xelsius Reactor Workstation,
for standalone-use there is an aluminum-block-stand, to be used with a magnetically stirred hotplate.
For solvothermal synthesis up to 200 bar there is a high-pressure version available, contact us for details.

OVERVIEW
The Pressure Reactor 15 bar is made for low-pressurized reactions, like hydrogenation of alkenes and alkynes.
This hermetically sealed reactor is characterized by a screw-in closure and magnetically coupled stirring. It offers a batch size of ~ 10 mL, which is suitable for reaction evaluation and process optimization.
For varying reaction conditions and tasks there are PTFE or Duran® glass reactor inlays,
wetted materials are PTFE, PEEK and FFKM providing high chemical resistance.
The integrated 3-way valve offers operational flexibility enabling seamless switching between multiple media sources or destinations, simplifying reagent dosing, product discharge, or inert gas purging – without the need to reconfigure tubing.
The multi-functional 2-port cap provides the gas-tight integration of tubes (1/8” & 1/16” feedthroughs) for flushing and sampling as well temperature sensors for monitoring and control.
The thin-walled pressure reactor design enables fast heat transfer between the reactor contents and the external heating source, also supporting better thermal homogeneity, ensuring uniform conditions throughout the vessel.
Gas-involved reactions under pressure (e.g., hydrogenation, carbonylation) benefit from a minimized dead volume of the reactor. A smaller gas headspace helps to maintain consistent partial pressures, thereby improving reaction kinetics, yield, and reproducibility. It also reduces the risk of gas-phase side reactions and lowers the total volume of hazardous gases, enhancing safety.
As standard the reaction pressure is indicated by an analog manometer.
Optionally a digital manometer – connected to the xelsius reactor work station and control software – enables monitoring of the reaction pressure during synthesis.
In case pressure exceeds 15 bar during synthesis a pressure relief valve opens automatically.
The pressure reactor is build according to the “Simple Pressure Vessel Directive 2014/29/EU”.
