The IKA LR-2 ST Jacketed Glass Reactor is a precision engineered laboratory reactor system designed for controlled mixing, stirring, and temperature regulated processing of small-scale chemical and formulation batches. Manufactured by IKA Works, the LR-2 ST is widely trusted in chemical synthesis, pharmaceutical R&D, cosmetics formulation, and academic research laboratories.
Engineered for accuracy, repeatability, and flexibility, this system integrates a double walled (jacketed) glass vessel with a high torque IKA Eurostar overhead stirrer, allowing precise control over reaction conditions across a wide viscosity range. Its modular architecture supports scale up studies, method development, and routine laboratory workflows with confidence.
The LR-2 ST is ideal for laboratories that require repeatable results, clean operation, and process transparency without moving to larger pilot scale reactor platforms.
