IKA ICC 150 lite Compact Immersion Circulator

Overview

The IKA ICC 150 lite is a compact, high-precision immersion circulator engineered for stable thermal control in laboratory applications requiring accurate heating and circulation of liquids in external baths or jacketed reactors. Based on Peltier-free resistive heating and PID-controlled PT1000 sensor feedback, the device delivers consistent thermal performance across its full operating range—from ambient temperature up to 150 °C—with stability maintained at ±0.05 K (as validated per DIN 12876 at +70 °C). Its modular immersion design enables direct integration into water, silicone oil, or heat-transfer fluid baths, supporting both internal recirculation (within the bath vessel) and external closed-loop circulation (e.g., to jacketed glass reactors or calorimeters). Designed in accordance with DIN 12876 Class III safety standards and marked FL for flammable liquid compatibility, the ICC 150 lite meets stringent European laboratory equipment requirements for continuous-duty operation under GLP-aligned conditions.

Key Features

• Compact footprint (135 × 303 × 180 mm) optimized for benchtop use without compromising thermal output or control fidelity
• Dual PT1000 temperature sensors—one for active PID control, one dedicated to independent safety cutoff—ensuring redundant thermal monitoring
• Heating power output of 2000 W, adjustable via digital interface to match thermal load and minimize overshoot
• Integrated pressure/suction pump delivering up to 15 L/min flow at zero backpressure, with max. pressure head of 0.3 bar and suction capability of 0.1 bar
• Comprehensive alarm system including LED status indicators, audible alerts, and programmable high/low liquid level detection (distinct from ICC 100 lite, which supports low-level only)
• DIN 12876-compliant construction with IP21 ingress protection, dual-stage overtemperature protection, and overvoltage safeguarding
• Front-panel LED display with 0.1 K resolution and ±0.1 K heating accuracy; safety temperature limit independently configurable from 0 to 160 °C

Sample Compatibility & Compliance

The ICC 150 lite is compatible with a broad range of heat-transfer media—including deionized water, glycol-water mixtures, silicone oils (up to 150 °C), and other non-corrosive, non-reactive fluids—provided minimum bath depth (≥150 mm) and chemical compatibility are verified. Its FL marking confirms suitability for use with flammable liquids under defined operational constraints. The unit complies fully with DIN 12876 Class III for immersion circulators, EN 61010-1 (safety of electrical equipment), and EN 60529 (IP21 enclosure rating). It supports audit-ready workflows under GLP and GMP environments through traceable parameter logging and software-integrated event tagging.

Software & Data Management

Control and documentation are enabled via native integration with labworldsoft™ software (Windows-based), accessible through standard USB 2.0 or RS232 serial interfaces. Users can remotely configure setpoints, ramp rates, hold times, and safety limits; monitor real-time temperature, flow status, and alarm events; and export timestamped CSV logs compliant with FDA 21 CFR Part 11 requirements when paired with appropriate user access controls and electronic signature modules. All parameter changes and system events are recorded with date/time stamps, supporting retrospective analysis and regulatory review.

Applications

• Temperature stabilization of analytical instruments (e.g., HPLC column ovens, viscometer baths, UV-Vis cuvette holders)
• Heating and circulation in jacketed reaction vessels for synthetic chemistry, polymerization, or enzymatic assays
• Calibration of thermometers, RTDs, and thermocouples against NIST-traceable references
• Material testing requiring controlled thermal ramping (e.g., thermal expansion, phase transition studies)
• Cell culture incubation support systems where precise bath temperature is critical to peripheral equipment
• QC/QA protocols in pharmaceutical and food laboratories requiring documented thermal consistency per ISO/IEC 17025

FAQ

Does the ICC 150 lite support refrigeration or cooling functionality?
No—it is a heating-only circulator. For combined heating/cooling applications, consider IKA’s RC series or external chiller integration.
What is the minimum required bath volume for stable operation?
While no fixed minimum volume is specified, a bath depth ≥150 mm and sufficient thermal mass (typically ≥2 L for water) are recommended to ensure stability and avoid rapid fluctuations.
Can the ICC 150 lite be used with silicone oil at 150 °C continuously?
Yes—provided the selected oil grade is rated for continuous service at 150 °C and the bath is adequately vented to prevent vapor buildup.
Is labworldsoft™ software included with the instrument?
Yes—the device ships with labworldsoft™ Basic Edition; advanced features (e.g., multi-device synchronization, Part 11 compliance modules) require optional licensing.
How is calibration traceability maintained?
The PT1000 sensors are factory-calibrated per DIN EN 60751; users may perform field verification using certified reference thermometers, and calibration records can be archived via labworldsoft™ export functions.
