IKA LR-2.ST Configuration 3 Modular Laboratory Reactor System

Overview

The IKA LR-2.ST Configuration 3 is a fully modular, jacketed laboratory reactor system engineered for scalable process development in fine chemical synthesis, pharmaceutical intermediate production, and catalytic reaction optimization. Built on the principle of controlled batch reaction engineering, it integrates precise mechanical agitation, thermal management via external circulator coupling to the double-wall LR 2000.2 vessel, and vacuum-compatible operation—all within a single, reconfigurable platform. The system operates under the Couette flow regime for consistent shear distribution and enables reproducible kinetic profiling through real-time torque-derived viscosity estimation. Its design complies with fundamental requirements for GLP-compliant lab-scale process validation, supporting early-stage technology transfer from bench to pilot plant.

Key Features

• Modular architecture: Interchangeable drive units, impellers, sensors, and accessories allow adaptation to diverse reaction types—including hydrogenation, nitration, emulsification, and crystallization.
• Jacketed 2 L borosilicate glass reactor (LR 2000.2): Designed for simultaneous heating/cooling via external thermostatic fluid circulation; compatible with IKA RTC 2 temperature controller and standard circulators (e.g., Huber, LAUDA).
• EUROSTAR 200 control P4 digital stirrer: Delivers up to 200 N·cm torque at speeds from 0 to 250 rpm, with closed-loop microprocessor regulation ensuring ±1 rpm stability even under variable load conditions.
• FFPM-sealed lid assembly: Chemically inert sealing system resistant to aggressive solvents (e.g., THF, DMF, chlorinated hydrocarbons) and thermal cycling from –80 °C to +200 °C.
• Integrated relative torque measurement: Enables non-invasive, continuous monitoring of rheological changes during reaction progress—critical for endpoint detection in polymerizations or precipitation reactions.
• Safety-certified interface: Includes hardware-based emergency stop, configurable overtemperature cutoff, and readiness for integration into facility-wide pressure/vacuum interlock networks per IEC 61511.

Sample Compatibility & Compliance

The LR-2.ST Configuration 3 accommodates heterogeneous, multiphase, and gas-liquid systems—including slurries, viscous pastes (<50,000 mPa·s), and exothermic oxidations. All wetted parts conform to USP Class VI and FDA 21 CFR 177.2600 standards for extractables testing. The FFPM gasket meets ASTM D1418 classification for fluorocarbon elastomers and demonstrates <0.5% volume swell after 72 h immersion in 95% sulfuric acid at 23 °C. System documentation supports audit readiness for ISO 9001:2015, ISO 14001, and EU GMP Annex 15 process validation frameworks.

Software & Data Management

While the base configuration operates via front-panel controls, optional IKA Labworldsoft™ v5.5 enables full PC-based logging of speed, torque, temperature (via Pt100 input), and time-stamped event markers. Data export complies with ASTM E2500-13 for raw data integrity and supports CSV/Excel formats for statistical analysis. When paired with validated electronic signatures and audit trail modules, the system satisfies FDA 21 CFR Part 11 requirements for regulated environments—particularly in API manufacturing process characterization studies.

Applications

• Reaction calorimetry screening using heat-flow correlation with torque trends
• Scale-down modeling of industrial hydrogenation reactors (e.g., Pd/C-catalyzed reductions)
• Crystallization kinetics studies under controlled supersaturation and seeding protocols
• Development of solvent-free or low-solvent formulations requiring high-shear dispersion
• Process safety evaluation (e.g., RC1-style adiabatic testing when coupled with external calorimeters)
• Continuous addition protocol optimization for Grignard or lithiation reactions

FAQ

What temperature range is achievable with the LR 2000.2 jacketed vessel?

With an external circulator, the system supports thermal operation from –80 °C to +200 °C, limited only by the performance envelope of the connected thermostat.
Can the system be upgraded to include pH or conductivity probes?

Yes—the lid features standardized 1/2″ NPT and 3/4″ Tri-Clamp ports; third-party probes (e.g., Mettler Toledo, Hamilton) may be integrated with appropriate feedthroughs and calibration workflows.
Is the torque signal calibrated for absolute viscosity quantification?

No—the relative torque output provides qualitative viscosity trend data; for quantitative rheology, a dedicated rotational viscometer (e.g., IKA RV series) is recommended as a complementary instrument.
Does IKA provide IQ/OQ documentation for this system?

Yes—factory-verified Installation Qualification (IQ) and Operational Qualification (OQ) protocols are available upon request, aligned with ASTM E2500-13 and ISO/IEC 17025 traceability requirements.
