The standard fixed bed reactor is a thick-walled glass column within a glass manifold. The reactor can be packed by the user providing flexibility. Fixed bed reactors may be used for workups, scavengers, solid-supported catalysts or solid-supported reagents. The temperature of the outside of the reactor wall is controlled. The glass components allow excellent visibility of the reactor contents.
Application examples
- Heterogeneous reagents – e.g. bases or drying media.
- Heterogeneous catalysis – Supported metal catalysts (Pd, Pt, Ni, Zn).
- Enzymatic catalysis – Immobilised enzymes
- Scavenger resins
- Solid-supported chemistry – Use of functionalised resins
- Inline purification – Polishing reactions
Tubular reactor features
- Ambient to 150 °C temperature range
- Optional 6.6 mm, 10 mm and 15 mm internal diameters
- Materials of construction PTFE, borosilicate glass FFKM seals
- Reactor volumes 3.5 ml to 18 ml
- Residence times 30 s to 350 minutes
- Pressure up to 20 bar at 150 °C dependant on reactor diameter
Key advantages
Vapourtec fixed bed reactors provide flexible, user-packed glass columns for heterogeneous reagents, catalysts, enzymes, and scavenger resins. They enable clean, continuous transformations, inline purification, and safe flow hydrogenation. Precise temperature control and excellent visibility ensure reliable performance.
Fixed bed reactors may be used for workups, scavengers, solid-supported catalysts, solid-supported reagents, or even to dispense reagents.
Max pressure depends on the bore of the column and, for larger sizes, temperature.
Note that the thermocouple is different from that on the tube reactor manifolds, and they are not interchangeable.
Fixed bed reactor diameters of 6.6 mm, 10 mm, and 15 mm diameters are supported and fittings and adapters are available with fixed and adjustable ends.
