Julabo MAGIO Series Expert Heating Circulating Bath

Overview

The Julabo MAGIO Series Expert Heating Circulating Bath is a high-precision, laboratory-grade temperature control system engineered for demanding external circulation applications requiring thermal stability, reproducibility, and long-term operational reliability. Designed and manufactured in Germany, the MAGIO series employs advanced PID-controlled resistive heating combined with a robust, continuously adjustable centrifugal circulation pump to deliver stable thermal energy across a wide operating range—from ambient +5 °C up to 300 °C. Its core architecture adheres to DIN 12876-1 Class III (FL) safety standards for flammable liquid environments, making it suitable for use with heat transfer oils, silicone fluids, and other non-aqueous media commonly employed in reaction calorimetry, material testing, and external jacketed reactor control. Unlike basic immersion baths, the MAGIO is purpose-built for closed-loop external temperature regulation—enabling precise thermal management of chromatography columns, spectroscopic cells, distillation apparatus, and custom-engineered process units.

Key Features

• High-stability temperature control with ±0.01 °C stability at setpoint—validated under steady-state conditions per ISO/IEC 17025 traceable calibration protocols.
• Adjustable circulation pump delivering 16–31 L/min flow rate and up to 0.92 bar outlet pressure, ensuring consistent thermal transfer even through extended tubing or high-backpressure systems.
• 7-inch high-resolution TFT display with intuitive swipe-based interface, real-time temperature curve visualization, and configurable user profiles—including optional bilingual (English/Chinese) firmware for regional deployment.
• Full stainless-steel wetted path (AISI 316L contact surfaces) ensures chemical compatibility with common organic solvents, glycols, and synthetic heat transfer fluids.
• Dual external sensor support: integrated PT100 input enables direct feedback from the target process zone—critical for applications where bath fluid temperature alone does not reflect actual sample thermal state.
• Modular communication architecture supporting USB-A (data export), USB-B (firmware update), RS232 (legacy integration), Ethernet (TCP/IP remote monitoring), and optional industrial protocols including Modbus RTU/TCP and Profibus DP for PLC-based lab automation.

Sample Compatibility & Compliance

The MAGIO series accommodates a broad spectrum of heat transfer media—including water, aqueous glycol mixtures, silicone oils (e.g., DC200 series), and mineral-based thermal fluids—with viscosity tolerance up to 1000 cSt at operating temperature. All models comply with DIN 12876-1 Class III (FL) requirements for flammable liquid handling, including explosion-proof housing design, overtemperature cut-off, dry-run protection, and certified electrical isolation. The system supports GLP/GMP-aligned operation through audit-trail-capable firmware (when paired with Julabo’s LabSoft software), meeting foundational expectations for data integrity under FDA 21 CFR Part 11 when configured with electronic signature and access control modules.

Software & Data Management

Julabo LabSoft software (Windows-based, optional license) provides full remote control, real-time graphing, automated protocol execution, and CSV/PDF report generation. Data logging intervals are configurable from 1 second to 60 minutes; all measurements include timestamp, setpoint, actual bath temperature, external sensor reading, and pump status. Firmware updates are delivered via signed USB-B packages to ensure cryptographic integrity. For enterprise integration, the built-in Ethernet interface supports HTTP API and OPC UA server functionality—enabling seamless connection to LIMS, SCADA, or MES platforms without middleware.

Applications

• External temperature control of jacketed reactors, rotary evaporators, and synthesis blocks in R&D and pilot-scale chemistry labs.
• Calibration of thermocouples, RTDs, and infrared sensors against NIST-traceable reference standards.
• Thermal conditioning of optical components, semiconductor test fixtures, and rheological measurement cells.
• Accelerated aging studies per ASTM D5721 and ISO 11346, where precise, sustained high-temperature exposure is required.
• Support of ISO/IEC 17025-accredited testing procedures requiring documented thermal uncertainty budgets and environmental monitoring logs.

FAQ

Does the MAGIO support refrigeration or only heating?
The MAGIO series is a heating-only circulating bath. For combined heating/cooling functionality, Julabo recommends the F26 or PRESTO series, which integrate compressor-based cooling modules.
Can the external PT100 sensor be used as the primary control input?
Yes—the controller supports dual-sensor mode: internal bath sensor for safety limiting and external PT100 for primary process feedback, enabling cascade-like control behavior.
Is the bath fluid volume adjustable within the tank?
No. Each MAGIO model has a fixed internal reservoir volume (e.g., MS-BC26 = 26 L nominal). However, the minimum fill level is defined by immersion depth requirements (150–200 mm), allowing partial filling for low-volume applications with appropriate pump priming precautions.
What certifications accompany standard delivery?
All units ship with CE marking, RoHS compliance documentation, DIN 12876-1 Class III (FL) conformity statement, and factory calibration certificate (traceable to DKD/DAkkS-accredited standards). Optional UKAS or ISO/IEC 17025 calibration certificates are available upon request.
How is maintenance performed on the circulation pump?
The pump assembly is sealed and maintenance-free under normal operating conditions. Julabo recommends annual inspection of inlet filtration and verification of impeller clearance using supplied service tools—no disassembly of the motor housing is required.
