CAT Reactors: 7, 18 or 24 Vial, Manual Catalysis Screening Reactor

CAT 7, 18 or 24 Vial, Manual Catalysis Screening Reactor

The CAT 7, 18, and 24 are manual catalyst screening reactors, supporting 7, 18, and 24 vials, respectively.  Each unit is a single vessel into which sample vials are placed, with the CAT 7 supporting 10 ml vials, the CAT 18, 2 ml vials, and the CAT 24 holding 4 ml vials.  The sample vials within the CAT reactor blocks are stirred and heated on a hot plate under manual operation.  They are held at the same pressure and temperature, enabling replicates to be performed within the same experiment, thereby accelerating development time.

Features and Options:

Vessel Types and Volumes


  • CAT 7: Designed to be used with 7 standard 10 ml vials

H.E.L Group

  • CAT 18: Designed to be used with 18 standard 2 ml vials

H.E.L Group

  • CAT 24: This allows the use of 24 open-top vials to be used at high pressure and temperature. The typical test volume is around 1 ml

H.E.L Group


  • All samples within each vessel are maintained at the same temperature and pressure, up to 100 bar / 250 °C.
  • Reactor block temperature can be monitored directly via a thermocouple probe.

Manual High-Pressure Reactor

  • Valves and pressure gauge provided to manually purge (for example, inert) and further pressurize with reacting gas (for example, hydrogenation), up to 100 bar.

 Stirring Available

  • Magnetic stirring in each reaction vial

Sample Integrity

  • To prevent carryover, the vials can be fitted with septa.
  • For larger vessels used in the CAT 7 and 24, the lids are fitted with cold fingers, which are chilled by an external coolant (eg tap water), to mitigate the crossover of vapors between reaction vessels.
