IKA ICC 150 lite pro 9 c Immersion Circulator

Overview

The IKA ICC 150 lite pro 9 c is a compact, high-precision immersion circulator engineered for stable, programmable temperature control in external baths and closed-loop systems. Designed according to DIN 12876 Class III safety standards for laboratory heating equipment, it employs a dual-sensor PID control architecture with independent PT1000 resistance thermometers—one for active temperature regulation and one for independent overtemperature protection. Its integrated pressure/suction pump enables both internal bath circulation and external recirculation applications, supporting precise thermal management of reaction vessels, jacketed reactors, viscometers, and analytical instrumentation requiring consistent thermal input between ambient and 150 °C. The device delivers 2100 W of heating power with a documented temperature stability of ±0.05 K under steady-state conditions—critical for kinetic studies, polymer curing, enzyme assays, and calibration traceability workflows.

Key Features

• Integrated dual-mode pump system supporting simultaneous pressure delivery (up to 0.3 bar) and suction capability (up to 0.1 bar), enabling flexible integration into external circulation loops or internal bath homogenization.
• PID-controlled heating with real-time LED display of both setpoint and measured temperature at 0.1 K resolution; control accuracy maintained within ±0.1 K across the full operating range.
• Dual-redundant PT1000 sensors: primary sensor for process control and secondary sensor for independent safety cutoff, configurable between 0 and 160 °C.
• Comprehensive alarm system featuring both visual (LED indicator) and audible alerts for overtemperature, sensor failure, low fluid level (indirectly inferred via thermal response anomalies), and pump blockage.
• Robust mechanical design compliant with DIN EN 60529 IP21 ingress protection, suitable for standard laboratory environments with controlled humidity (≤80 % RH) and ambient temperatures from 5 to 40 °C.
• Standard digital interfaces include RS232 and USB-B ports, facilitating direct connection to PCs for remote parameter setting, data logging, and integration into automated lab platforms adhering to GLP/GMP documentation requirements.

Sample Compatibility & Compliance

The ICC 150 lite pro 9 c is compatible with stainless steel bath vessels (e.g., IB 9 pro), silicone oil, glycol-water mixtures, and other non-corrosive heat-transfer fluids rated for continuous operation up to 150 °C. It meets DIN 12876 Class III specifications for laboratory heating devices, ensuring mechanical integrity, electrical safety, and thermal hazard mitigation during unattended operation. Its design supports compliance with ISO/IEC 17025 calibration environment requirements when used in conjunction with traceable reference thermometers. While not intrinsically explosion-proof, its construction excludes ignition sources and conforms to general-purpose laboratory electrical safety norms (IEC 61010-1). For regulated environments, audit trails generated via RS232/USB can be archived to satisfy FDA 21 CFR Part 11 electronic record retention expectations where validated software protocols are implemented externally.

Software & Data Management

The circulator operates autonomously without proprietary software but provides ASCII-based serial communication protocols via RS232 and USB-B interfaces. Command sets support reading current temperature, setting target values, adjusting ramp rates, enabling/disabling alarms, and querying status flags. When connected to laboratory information management systems (LIMS) or custom Python/C# applications, users may log timestamped temperature profiles, trigger event-based notifications, and synchronize thermal events with analytical instrument acquisition cycles. All interface operations retain full traceability: no parameters are modifiable without explicit command transmission, and no configuration changes persist across power cycles unless saved to non-volatile memory—a feature supporting ALCOA+ data integrity principles.

Applications

• Thermal conditioning of samples prior to rheological, spectroscopic, or chromatographic analysis.
• Temperature-controlled enzymatic digestion and protein denaturation studies requiring tight thermal reproducibility.
• Calibration of thermocouples, RTDs, and infrared thermometers against NIST-traceable references in liquid baths.
• Supporting ASTM D341 viscosity-temperature correlation measurements using calibrated oil baths.
• Providing stable thermal input to jacketed glass reactors during exothermic synthesis under GLP-compliant workflows.
• Acting as a primary temperature source in multi-instrument thermal networks, including dissolution testers and accelerated stability chambers.

FAQ

What is the minimum recommended bath depth for stable operation?
The unit requires a minimum fluid depth of 150 mm to ensure adequate submersion of the heating element and temperature sensor, preventing dry-run damage and ensuring accurate feedback control.
Can this circulator be used with silicone oil at 150 °C continuously?
Yes—when paired with DIN 12876-compliant stainless steel vessels (e.g., IB 9 pro) and thermally stable silicone oils rated for >150 °C long-term service, continuous operation is permitted per manufacturer specifications.
Does the device support external temperature probe input for cascade control?
No—the ICC 150 lite pro series relies solely on its integrated PT1000 sensors; external probe inputs are not supported in this model variant.
Is firmware update capability available?
Firmware updates are performed exclusively by authorized IKA service centers using diagnostic hardware; end users cannot modify or upgrade firmware independently.
What safety certifications does the unit carry beyond DIN 12876?
It complies with IEC 61010-1 for electrical safety and bears CE marking for conformity with EU Low Voltage and EMC directives; full test reports are available upon request from IKA Technical Documentation.
