IKA LR-2 ST Jacketed Stainless Steel Reactor

500–2000 mL | High-Torque | Temperature-Controlled | Pilot-Ready

The IKA LR-2 ST Jacketed Stainless Steel Reactor is a rugged, precision laboratory reactor system designed for scientists and engineers who need more durability, better heat transfer, and safer operation than traditional glass reactors can provide.

Built by IKA Works, this stainless-steel configuration of the LR-2 ST is ideal for aggressive chemistries, high-viscosity formulations, elevated temperatures, and pressure or vacuum applications, all while maintaining precise control and reproducibility.

If your processes are pushing the limits of glass, the IKA LR-2 ST Stainless Steel Reactor is the upgrade your lab needs.

Why Labs Choose the Stainless Steel LR-2 ST 

✔ Stronger & safer than glass for pressure, vacuum, and harsh chemicals
✔ Superior heat transfer for faster, more uniform temperature control
✔ High-torque mixing for gels, polymers, resins, and viscous products
✔ Compact pilot-scale capacity without moving to large reactors
✔ Trusted IKA engineering used worldwide in regulated labs

This reactor is built for labs that can’t afford downtime, breakage, or inconsistent results.
