IKA ICC 150 lite pro 20 Immersion Circulator

Overview

The IKA ICC 150 lite pro 20 is a compact, high-precision immersion circulator engineered for laboratory-grade temperature control in external bath systems. Designed according to DIN 12876 Class III safety standards for heating-only applications, it delivers stable thermal regulation from ambient up to 150 °C—making it suitable for oil baths, silicone fluid baths, and high-temperature water-based media where extended dwell times and reproducible thermal profiles are critical. Its integrated pressure/suction pump enables both internal recirculation within the bath vessel and external circulation through auxiliary equipment such as jacketed reactors, viscometers, or analytical cells. The device operates on a dual-sensor architecture: one PT1000 sensor governs active PID temperature control, while a second independent PT1000 serves as a redundant safety cutoff—programmable between 0 °C and 160 °C—to prevent overheating under fault conditions. With a certified temperature stability of ±0.05 K and display resolution of 0.1 K, the ICC 150 lite pro 20 meets the metrological requirements of ISO/IEC 17025-accredited laboratories performing method validation or routine QC testing.

Key Features

• Robust 2100 W heating output with rapid thermal response and minimal overshoot due to adaptive PID algorithm
• Dual PT1000 sensing system: primary control sensor + independently wired safety sensor with adjustable limit
• Integrated pressure/suction pump delivering up to 15 L/min flow at zero backpressure and 0.3 bar max pressure
• Compliance with DIN 12876 Class III (FL-marked for flammable media compatibility) and IP21 ingress protection
• Full continuous-duty operation (100% duty cycle) validated for unattended 24/7 use in regulated environments
• RS232 and USB-B interfaces supporting remote parameter setting, real-time data logging, and firmware updates
• Visual and audible alarm system with LED status indicators for temperature deviation, sensor fault, and pump failure
• Compact footprint (135 × 303 × 180 mm) and lightweight design (4.7 kg) optimized for benchtop integration and modular lab setups

Sample Compatibility & Compliance

The ICC 150 lite pro 20 is compatible with standard laboratory bath vessels—including stainless-steel tanks (e.g., IKA IB 20 pro, 20 L capacity) and custom jacketed systems—provided minimum immersion depth of 150 mm is maintained. It supports thermal media ranging from deionized water and glycol-water mixtures to silicone oils and heat-transfer fluids rated for continuous operation at 150 °C. As a DIN 12876 Class III FL device, it is certified for use with flammable liquids when installed per manufacturer guidelines and paired with appropriate containment and ventilation. The unit conforms to EU Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility Directive 2014/30/EU. Its safety architecture satisfies prerequisites for GLP-compliant thermal validation studies and supports audit-ready documentation when used with IKA Labworld software.

Software & Data Management

Remote configuration and monitoring are enabled via IKA Labworld software (Windows-compatible), which provides full access to setpoint programming, ramp/soak profiles, real-time temperature graphing, and event-triggered data export (CSV). All operational parameters—including actual temperature, setpoint, pump status, and alarm history—are timestamped and stored locally or streamed over RS232/USB. The device supports 21 CFR Part 11-compliant workflows when deployed with validated software versions: electronic signatures, user-level access control, and immutable audit trails for temperature excursions or safety-limit interventions can be implemented through integrated policy enforcement modules. Firmware updates preserve calibration integrity and are traceable via version-locked checksum verification.

Applications

• Temperature stabilization of analytical instruments requiring precise thermal coupling (e.g., UV-Vis spectrophotometers, differential scanning calorimeters)
• Controlled heating of reaction mixtures in glass-jacketed reactors during kinetic studies or synthesis optimization
• Calibration of thermometers, RTDs, and thermocouples across extended ranges (20–150 °C) per ASTM E74 and ISO 17025 Clause 6.5
• Viscosity measurement support for rotational rheometers using thermostatted sample holders
• Accelerated stability testing of pharmaceutical formulations per ICH Q1A(R3) guidelines
• Material testing under elevated temperatures, including polymer melt index determination and thermal aging protocols

FAQ

What is the minimum required bath depth for safe operation?
The immersion probe must be submerged to a minimum depth of 150 mm to ensure adequate thermal mass coupling and prevent dry-run damage to the heater element.
Can this unit cool as well as heat?
No—the ICC 150 lite pro 20 is a heating-only circulator. For cooling capability, consider IKA’s RC series or integrate with an external chiller via the external circulation port.
Is DIN 12876 Class III certification sufficient for use with silicone oil?
Yes—Class III FL designation explicitly permits operation with non-aqueous, flammable, and high-boiling-point media such as dimethylsilicone oils when used within specified temperature limits and proper ventilation.
Does the device support automatic calibration verification?
While not self-calibrating, the dual PT1000 architecture allows for periodic verification against NIST-traceable reference probes; calibration records may be archived with time-stamped logs via Labworld software.
What maintenance intervals are recommended for long-term reliability?
Annual inspection of pump seals, cleaning of heat exchanger surfaces, and verification of safety sensor response time are advised per IKA Maintenance Protocol MP-ICC-2023; no consumables require scheduled replacement under normal operating conditions.
