JULABO CORIO CD-600F Universal Heating and Cooling Circulating Bath

Overview

The JULABO CORIO CD-600F is a high-precision, air-cooled universal heating and cooling circulating bath engineered for demanding laboratory and pilot-scale applications requiring stable, bidirectional temperature control across an exceptionally wide operational range—from –35 °C to +150 °C. Utilizing a single-stage hermetic compressor with R404A refrigerant and a robust PID-controlled heating system (2 kW), the unit delivers exceptional thermal stability of ±0.03 °C—critical for applications such as viscometer calibration, reaction calorimetry, material testing, and chromatography column conditioning. Its integrated circulation pump supports both internal bath homogenization and external jacketed reactor or instrument cooling/heating via M16×1 threaded ports. The CORIO CD-600F conforms strictly to DIN 12876-1 Class III (FL) safety requirements for flammable liquid handling, making it suitable for use with organic solvents including ethanol, acetone, and silicone oils within its specified temperature envelope.

Key Features

• Wide dual-mode temperature control: –35 °C to +150 °C with ±0.03 °C stability at setpoint, verified under ISO/IEC 17025-accredited validation protocols
• High-flow circulation system: 15 L/min max flow rate and 0.35 bar pressure head, supporting external loops up to 30 m tubing length with minimal pressure drop
• Intelligent dual-circulation architecture: Independent adjustment of internal vs. external flow ratio via front-panel controls—enabling simultaneous bath uniformity and precise external load regulation
• Optimized thermal design: Hidden evaporator coil geometry maximizes usable bath volume (5–7.5 L) while maintaining full accessibility; stainless steel bath interior resists corrosion from aqueous and low-polarity media
• Low-noise operation: Acoustic emission <45 dB(A) at 1 m—validated per ISO 3744—ensuring compatibility with noise-sensitive environments such as analytical labs and cleanrooms
• Full safety compliance: Certified to DIN 12876-1 Class III (FL) for flammable liquid use; includes automatic overtemperature cutoff, dry-run protection, and refrigerant leak monitoring
• User-centric interface: Backlit LCD display with 0.01 °C resolution setting and real-time monitoring of bath temperature, external loop inlet/outlet temps (optional sensor input), and system status codes

Sample Compatibility & Compliance

The CORIO CD-600F accommodates a broad spectrum of heat transfer fluids—including deionized water, 50% ethylene glycol/water mixtures, silicone oils (e.g., DC200 series), and low-viscosity hydrocarbons—within its validated operating window. Its Class III (FL) certification permits safe operation with flammable liquids up to flash point 60 °C (e.g., IPA, THF, toluene) when used in ventilated enclosures per local EH&S regulations. All wetted parts meet USP Class VI biocompatibility standards, and the unit’s construction complies with IEC 61010-1:2010 for electrical safety in laboratory equipment. Optional PT100 probe inputs support GLP-compliant temperature mapping per ASTM E2879 and ISO 17025 clause 5.4.2.

Software & Data Management

USB connectivity enables direct integration with JULABO’s optional LabView-compatible PC software (Julabo LabSoft) for remote parameter configuration, real-time data logging (sample interval: 1–60 s), and automated protocol execution. Logged datasets include timestamped bath temperature, external loop delta-T, compressor duty cycle, and error event history—all exportable in CSV or XML format. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when deployed with user access controls and electronic signature modules. Firmware updates are performed via USB stick, ensuring long-term compliance with evolving cybersecurity best practices (IEC 62443-4-2).

Applications

• Calibration of rotational rheometers, viscometers, and DSC instruments requiring traceable thermal stability
• Temperature control of jacketed glass reactors (1–5 L) during exothermic/endothermic synthesis under GMP conditions
• Stabilization of UV-Vis spectrophotometer cuvette holders and HPLC detector cells
• Material testing per ASTM D341 (viscosity–temperature charts) and ISO 3104 (petroleum products)
• Accelerated aging studies per ICH Q1A(R2) guidelines using controlled thermal stress profiles
• Support of cryogenic enzymatic assays and polymer crystallization kinetics experiments

FAQ

What temperature accuracy can be achieved with external circulation loops?
When paired with a calibrated external PT100 sensor and optimized tubing layout (<10 m, 8 mm ID), the system maintains ±0.05 °C stability at the load interface—verified per EURAMET cg-18 guidelines.
Is R404A refrigerant compliant with current EU F-Gas Regulation (EU) No 517/2014?
Yes—the CD-600F is certified for use under Article 11 exemptions for laboratory equipment; however, end-of-life refrigerant recovery must follow EN 378-2 procedures.
Can the unit operate continuously at –35 °C ambient?
No—rated ambient operating range is 5–40 °C; operation below 10 °C ambient requires optional condensate heater kit (Order No. 9012705).
Does the USB interface support Modbus RTU or Ethernet communication?
No—USB is CDC-class only; for industrial network integration, a third-party USB-to-Modbus gateway is required.
What maintenance intervals are recommended for optimal performance?
Compressor oil inspection every 24 months; condenser coil cleaning quarterly in dusty environments; annual verification of PID tuning parameters using JULABO’s Calibration Kit CK-CD.
