Overview
The JULABO MS-1000F is a high-precision, dual-function heating and cooling circulating bath engineered for demanding laboratory and pilot-scale applications requiring exceptional thermal stability, wide operational range, and robust external temperature control. Utilizing JULABO’s proprietary Intelligent Control Circuit (ICC) technology, the MS-1000F delivers real-time adaptive PID regulation with dynamic compensation for load changes, ambient fluctuations, and heat exchange dynamics—ensuring ±0.01 °C temperature stability across its full operating span from –50 °C to +200 °C. Unlike single-mode thermostats, the MS-1000F integrates a high-efficiency cascade refrigeration system with a high-power resistive heating circuit, enabling seamless transition between sub-zero cooling and high-temperature operation without manual intervention or system reconfiguration. Its stainless steel fluid-contact components—including the reservoir, pump head, and internal cooling coil—are passivated and electropolished to resist corrosion from water, silicone oils, glycol-water mixtures, and other common heat transfer media, including flammable liquids certified under DIN 12876-1 Class S3.
Key Features
- Intelligent Control Circuit (ICC): Adaptive algorithm continuously optimizes refrigeration compressor duty cycle and heater power output based on real-time thermal load, minimizing overshoot and stabilizing setpoints within seconds.
- Dual-pump architecture: Independent pressure and suction pumps enable precise flow control across variable backpressure conditions; flow rate adjustable from 16 to 31 L/min with pressure output ranging from 0.24 to 0.92 bar and suction capability up to 0.4 bar.
- Large-format TFT color touchscreen (7″): Supports multi-language UI (English, German, French, Spanish, Chinese), customizable home screens (data-only, data+curve, trend-only), and intuitive navigation with context-sensitive help overlays.
- Comprehensive connectivity suite: Standard USB host/device, RS232, and Ethernet ports support remote monitoring, firmware updates, and integration into centralized lab management systems; analog I/O (0–10 V / 4–20 mA) available as optional module for PLC interfacing.
- Optimized mechanical design: Integrated cooling coil located beneath the controller housing maximizes usable bath volume (21–30 L); front-mounted drain valve enables rapid, spill-free fluid exchange; compact footprint (42 × 49 × 70 cm) allows side-by-side installation without ventilation clearance.
- Programmable thermal profiles: Up to eight independent programs, each supporting up to 60 time-temperature steps with ramp rate definition (°C/min), hold duration, and event-triggered outputs (e.g., relay activation upon reaching target).
Sample Compatibility & Compliance
The MS-1000F is validated for use with a broad spectrum of heat transfer fluids—including deionized water, 50/50 ethylene glycol/water, silicone oils (e.g., DC200 series), and mineral oils—provided viscosity remains within pump specifications (< 100 cSt at operating temperature). Its DIN 12876-1 Class S3 certification permits safe operation with flammable liquids (flash point ≥ 60 °C), making it suitable for applications involving organic solvents in reaction calorimetry or synthesis modules. All electrical components meet CE, UL 61010-1, and EMC Directive 2014/30/EU requirements. For regulated environments, the device supports audit-ready operation when paired with JULABO’s optional software package, which logs all parameter changes, setpoint modifications, and alarm events with timestamped, user-identifiable entries compliant with FDA 21 CFR Part 11 (electronic records/signatures) and GLP/GMP documentation standards.
Software & Data Management
JULABO’s LabSoft Pro software (Windows-based, included) provides full bidirectional communication via Ethernet or USB. It enables real-time graphing of temperature, flow rate, compressor status, and heater power; automated export of CSV-formatted datasets with metadata (operator ID, method name, instrument serial number); and secure password-protected user roles (Operator, Supervisor, Administrator). The software also supports method validation protocols—including IQ/OQ templates aligned with ISO/IEC 17025—and generates PDF reports with embedded calibration certificates. Remote access is supported through TLS-encrypted web interface, allowing off-site monitoring and intervention during extended experiments without physical presence.
Applications
- Reaction calorimetry and exothermic process control in pharmaceutical development and fine chemical synthesis.
- Temperature-dependent material testing (e.g., rheology, DSC sample staging, viscometry baths).
- Chromatography column oven integration (HPLC, UHPLC) requiring stable gradient-compatible thermal environments.
- Calibration of temperature sensors (RTDs, thermistors, thermocouples) per ISO/IEC 17025 accredited procedures.
- Environmental stress screening of electronic components and polymer specimens under controlled thermal cycling.
- Bioreactor jacket temperature control in upstream bioprocessing workflows.
FAQ
What types of heat transfer fluids are compatible with the MS-1000F?
Deionized water, aqueous glycol solutions, silicone oils (e.g., Dow Corning DC200), and mineral oils are routinely used. Fluids must have flash points ≥ 60 °C for Class S3 compliance.
Does the MS-1000F support external temperature feedback control?
Yes—via optional PT100 or thermistor input; the unit can accept signals from an external probe immersed in the application system and regulate bath output to maintain the external setpoint.
Is the ICC temperature control algorithm configurable?
No—the ICC is fully embedded and non-user-adjustable; however, it automatically adapts to changing thermal loads without manual tuning, ensuring optimal performance across diverse applications.
Can multiple MS-1000F units be synchronized for coordinated thermal profiling?
Yes—using LabSoft Pro’s network mode, up to 16 units can be managed from a single workstation with synchronized start/stop triggers and shared method libraries.
What maintenance intervals are recommended for long-term reliability?
Annual inspection of refrigerant charge, pump seals, and coolant filter (if installed); biannual verification of temperature sensor accuracy using NIST-traceable reference probes.
