IKA 5L Dual-Jacketed Glass Reactor System

Overview

The IKA 5L Dual-Jacketed Glass Reactor System is a precision-engineered benchtop reactor platform designed for controlled small-scale chemical synthesis, kinetic studies, crystallization, hydrogenation, and multi-step reaction workflows under variable thermal and pressure conditions. Its core architecture integrates a borosilicate glass 3.3 vessel with a dual-jacket configuration: an inner circulation jacket for active temperature control (via external chiller/heater), and an outer vacuum-insulated jacket that minimizes parasitic heat exchange with ambient air. This design enables stable operation across an extended thermal range—from cryogenic −90 °C to high-temperature +230 °C—while maintaining <60 °C thermal shock tolerance between internal and external surfaces. The system adheres to fundamental principles of process intensification: enhanced heat transfer efficiency, reduced thermal inertia, and improved reproducibility in exothermic or endothermic reactions. All wetted components—including sealing elements, stirrer shaft seals, and discharge valves—are constructed from chemically inert, high-purity materials (PTFE, FFKM, FKM) certified for compatibility with aggressive reagents, halogenated solvents, and strong acids/bases.

Key Features

• Dual-jacket thermal management: Inner jacket supports precise ±0.2 °C temperature regulation via external fluid circulation; outer vacuum jacket reduces radial heat loss by >70% compared to single-jacket systems—critical for low-temperature reactions and energy-efficient heating.
• Modular lid assembly with six standardized ground-glass ports (SQG 29/42 and TS 24/40) enabling simultaneous integration of temperature probes, pH electrodes, reflux condensers, addition funnels, gas inlets, and sampling valves without cross-contamination.
• High-integrity mechanical seal: Magnet-coupled drive with FFKM dynamic seals rated for continuous operation up to 800 rpm, ensuring leak-tight performance under vacuum (down to 0.5 mbar) and positive pressure.
• Zero-dead-volume bottom discharge valve with PTFE-lined body and FFKM seat—designed for complete, residue-free material evacuation and compatible with slurries and viscous media.
• Optimized impeller geometry support: Interchangeable anchor, paddle, turbine, and helical ribbed impellers mount via ISO-KF 25 flange interface; all blades are PTFE-coated or fully PTFE-molded to prevent metal leaching.
• Tool-free assembly/disassembly: Quick-release clamps, pre-aligned port gaskets, and integrated leveling feet simplify setup, cleaning, and maintenance—reducing downtime between campaigns.

Sample Compatibility & Compliance

The reactor accommodates liquid, slurry, suspension, and semi-solid reaction mixtures with viscosities up to 50,000 mPa·s. Its borosilicate glass 3.3 construction meets DIN ISO 3585 specifications for hydrolytic resistance (Class HGB 1), while PTFE/FFKM elastomers comply with USP Class VI and FDA 21 CFR 177.1550 for food-contact and pharmaceutical use. The system supports IQ/OQ documentation packages aligned with ASTM E2500–22 and EU Annex 15 guidelines. Vacuum integrity is validated per ISO 2859-1 sampling plans, and temperature uniformity across the vessel volume is verified using calibrated PT100 sensors traceable to NIST standards. Full audit trail capability is available when integrated with IKA Labworld software (optional).

Software & Data Management

When paired with IKA Labworld Control software (v4.2+), the reactor enables synchronized logging of stirring speed, jacket temperature, internal probe temperature, pressure, and torque—sampled at 1 Hz resolution. Data export complies with ASTM E2500-defined metadata structures, including timestamped operator ID, method version, and instrument calibration status. Electronic signatures, role-based access control, and 21 CFR Part 11-compliant audit trails are supported through optional GxP license modules. Raw data files (.csv, .xlsx, .iwd) retain full traceability to sensor serial numbers and calibration certificates.

Applications

• Process development for API synthesis under controlled cooling ramp profiles (e.g., lithiation at −78 °C followed by gradual warming).
• Screening of heterogeneous catalysis (e.g., Pd/C hydrogenations) with real-time torque monitoring to detect catalyst deactivation.
• Crystallization optimization via supersaturation control, where precise jacket temperature gradients govern nucleation kinetics.
• Emulsion polymerization requiring strict oxygen exclusion and shear-sensitive monomer addition sequences.
• Green chemistry workflows using supercritical CO₂ or low-GWP refrigerants as reaction media—enabled by vacuum-rated construction and low-thermal-mass design.

FAQ

Can this reactor be used for reactions under inert atmosphere?
Yes—the sealed lid configuration with multiple gas-tight ports supports continuous nitrogen or argon purging, and vacuum-backfill cycles compliant with Schlenk-line protocols.
Is the vacuum jacket serviceable or refillable?
The outer vacuum jacket is permanently evacuated and sealed during manufacturing; no user maintenance is required. Vacuum integrity is guaranteed for ≥5 years under normal lab handling.
What temperature sensors are included by default?
One Pt100 probe (Class A, 3-wire) is supplied for internal reaction mass monitoring; optional second probe for jacket inlet/outlet tracking is available.
Does the system support automated dosing integration?
Yes—standard RS485 and analog 0–10 V interfaces allow seamless connection to third-party syringe pumps or mass flow controllers via IKA Labworld’s open API.
How is cleaning validation performed?
The smooth, crevice-free interior surface, absence of weld seams, and full disassembly capability enable swab testing and rinse recovery studies per ICH Q5C and USP .
