Ai R5 5L Compact Single Jacketed Glass Reactor
The Ai R5 5L Single Jacketed Glass Reactor is a compact, reliable, and versatile reaction system designed for laboratory-scale synthesis, research, formulation, and process development.
With a 5L high-borosilicate glass reaction vessel, the R5 provides greater processing capacity while maintaining a relatively compact footprint, making it an excellent choice for laboratories that require more capacity than a small benchtop reactor without moving to a substantially larger reactor system.
The jacketed vessel can be connected to an external heating and cooling circulator to provide controlled reaction temperatures across a wide operating range. Adjustable mechanical stirring, a constant-pressure feeding funnel, and a large-surface-area condenser support controlled mixing, reagent addition, reflux, condensation, and solvent recovery.
Built with durable high-borosilicate glass, solvent-resistant PTFE sealing components, and a stainless-steel reinforced PTFE agitator, the R5 is designed for dependable day-to-day laboratory operation. Digital speed and material temperature displays provide convenient process monitoring, while the robust supporting frame provides excellent stability during operation.

Features
- Compact 5L reactor system – combines useful laboratory-scale processing capacity with a relatively small footprint.
- Reliable laboratory performance – designed for routine synthesis, R&D, formulation, and small-batch processing.

- Digital speed and temperature display – allows convenient real-time monitoring of stirring speed and material temperature.
- Thermal insulation jacket included – helps reduce heat loss or heat gain, improves temperature stability, and reduces condensation or frosting during low-temperature operation.
- Heavy-duty support structure – provides a stable and durable platform for regular laboratory use.
- CE compliant – UL and CSA compliance available as optional configurations.
- AU-based service and support – backed by a one-year warranty with local parts, technical assistance, and after-sales support.
Typical Applications
The Ai R5 is well suited for chemical synthesis, pharmaceutical research, material development, formulation, crystallisation, extraction, reflux, solvent recovery, mixing, and general laboratory process development.
Its combination of 5L capacity, compact footprint, reliable stirring, temperature control capability, and vacuum compatibility makes the R5 particularly suitable for universities, research laboratories, start-ups, pilot laboratories, and industrial R&D facilities requiring a dependable small-scale glass reactor.
