IKA ICC 150 lite pro 12 Immersion Circulator

Overview

The IKA ICC 150 lite pro 12 is a compact, high-precision immersion circulator engineered for stable, reproducible temperature control in laboratory-scale liquid baths and external jacketed reactors. Designed according to DIN 12876 Class III safety standards—and FL-marked for use with flammable media—the device employs dual PT1000 resistance temperature detectors (one for process control, one for independent safety cutoff) and a digital PID algorithm to maintain thermal stability within ±0.05 K across its full operating range (ambient to 150 °C). Its integrated pressure/suction pump enables both internal bath circulation and closed-loop external circulation (e.g., to jacketed flasks or reactor vessels), supporting applications requiring precise heat transfer without external pump integration. The unit operates continuously at full load (2100 W heating power) and features a robust stainless-steel housing, IP21 ingress protection, and compliance with EU Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU).

Key Features

• High-stability temperature control: ±0.05 K stability (DIN 12876 verified) with 0.1 K display resolution and ±0.1 K heating accuracy
• Dual-sensor architecture: Primary PT1000 for PID regulation + redundant PT1000 safety sensor with user-adjustable cutoff (0–160 °C)
• Integrated dual-mode pump: Delivers up to 15 L/min flow at 0 bar backpressure; sustains 0.3 bar pressure and 0.1 bar suction—enabling reliable external circulation
• FL-certified design: Complies with DIN 12876 Class III requirements for flammable liquid handling, including thermal cut-off redundancy and flame-resistant housing
• Digital connectivity: Standard RS232 and USB-B interfaces support instrument integration into lab networks, automated workflows, and regulatory-compliant data logging
• Continuous-duty certified: Rated for 100% duty cycle under nominal load; validated for unattended operation in GLP/GMP environments
• Compact footprint: 135 × 303 × 180 mm (W×H×D); 4.7 kg mass—optimized for benchtop deployment alongside IB 12 pro stainless-steel baths or third-party vessels

Sample Compatibility & Compliance

The ICC 150 lite pro 12 is compatible with water, silicone oils, glycol/water mixtures, and other thermally stable heat-transfer fluids suitable for operation up to 150 °C. It supports bath depths ≥150 mm and is routinely deployed with IKA’s IB 12 pro stainless-steel bath (M-size) or custom jacketed glassware. Regulatory alignment includes DIN 12876 Class III (safety classification for thermostats used with flammable liquids), CE marking per Machinery Directive 2006/42/EC, and electromagnetic compatibility per EN 61326-1. For regulated environments, the device supports audit-trail-capable software via RS232/USB, enabling compliance with FDA 21 CFR Part 11 when paired with validated acquisition platforms.

Software & Data Management

While the ICC 150 lite pro 12 operates autonomously via front-panel controls, its RS232 and USB-B ports allow bidirectional communication with PC-based control suites (e.g., IKA Labworld software or third-party SCADA systems). Users can remotely configure setpoints, monitor real-time temperature curves, log sensor outputs (working + safety), and trigger alarms programmatically. All parameter changes are timestamped and stored in non-volatile memory—supporting traceability requirements under ISO/IEC 17025 and GxP frameworks. Firmware updates are delivered via USB, ensuring long-term compatibility with evolving laboratory informatics infrastructure.

Applications

• Calibration of temperature-sensitive analytical instruments (e.g., viscometers, densimeters, refractometers)
• Thermal conditioning of samples prior to HPLC, GC, or spectroscopic analysis
• Controlled heating in synthetic chemistry—especially Grignard reactions, esterifications, and polymerizations requiring precise bath-level thermal uniformity
• Stability testing per ICH Q1A(R2) guidelines using jacketed vessels
• Material testing per ASTM D2196 (viscosity of non-Newtonian fluids) and ISO 2555 (solution viscosity)
• Enzyme kinetics assays requiring sustained 37–95 °C incubation with minimal thermal drift

FAQ

Can the ICC 150 lite pro 12 be used with oil baths above 100 °C?
Yes—it is FL-certified and rated for continuous operation up to 150 °C with silicone or mineral oils meeting DIN 51502 specifications.
Does it support external cooling via chiller integration?
No—the ICC 150 lite pro 12 is a heating-only circulator. For combined heating/cooling, consider the IKA RC basic or RV series with external chiller coupling.
Is the USB interface compatible with modern Windows/macOS systems?
Yes—USB-B connection uses standard CDC ACM class drivers; no proprietary software installation required for basic serial communication.
What is the minimum bath depth required for stable operation?
A minimum liquid depth of 150 mm is required to ensure full submersion of the heating element and pump inlet, preventing dry-run damage and ensuring thermal homogeneity.
How is traceability ensured during GMP audits?
Through timestamped parameter logs, dual-sensor validation records, and configurable alarm events—all accessible via RS232/USB and exportable in CSV format for audit documentation.
