Ai R2 2L Compact Benchtop Glass Reactor
The Ai R2 2L Single Glass Reactor is a compact, reliable, and versatile benchtop reaction system designed for laboratory-scale synthesis, research, formulation, and process development.
Featuring a 2L high-borosilicate glass jacketed vessel, the R2 provides excellent chemical resistance and clear visibility of the reaction process. Its compact footprint makes it particularly suitable for laboratories where bench space is limited, while still providing the essential functions of a full jacketed reactor system.
The reactor features adjustable mechanical stirring, a constant-pressure addition funnel, and an efficient glass condenser, allowing controlled mixing, reagent addition, reflux, and solvent recovery. When connected to a suitable heating/cooling circulator and vacuum pump, the R2 can provide a controlled temperature and vacuum environment for a wide range of small-scale laboratory processes.
Built with durable borosilicate glass, chemical-resistant PTFE components, and a stainless-steel reinforced PTFE agitator, the R2 is designed for dependable day-to-day laboratory operation and easy process observation.

Typical Applications
Ideal for chemical synthesis, pharmaceutical research, material development, formulation, crystallisation, extraction, reflux, solvent recovery, mixing, and general laboratory R&D.
The Ai R2 is particularly suited to universities, research laboratories, start-ups, and industrial R&D facilities looking for a compact and dependable 2L glass reactor for small-scale reaction work.
Your safety is important to us! Please use caution when operating. Users of glass reaction equipment must take all necessary precautions to avoid contact with rotating parts, particularly the entanglement of loose clothing, hair, necklaces, or other jewelry. Under these circumstances, the winding action of the rotating parts can draw the user(s) into the apparatus, resulting in the breakage of glassware, burns, and/or chemical exposure. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
