Overview
The Thermo Fisher SuperNuova+™ Series Hotplate Stirrers are precision-engineered benchtop instruments designed for reproducible, thermally stable mixing in research, pharmaceutical development, biotechnology, and synthetic chemistry laboratories. Combining magnetic stirring with independent, high-fidelity heating control, these devices operate on the principle of contactless torque transfer via rotating magnetic fields—enabling consistent agitation across viscous, heterogeneous, or temperature-sensitive samples without mechanical wear or seal degradation. Unlike conventional hotplates, the SuperNuova+™ integrates StirTrac™ technology, which dynamically couples motor torque to magnetic field strength to maintain low-speed stability (<100 rpm) while delivering robust performance at maximum rotational speeds (up to 1200 rpm). This architecture ensures minimal vibration, reduced sample splashing, and improved thermal homogeneity—critical for kinetic studies, crystallization protocols, dissolution testing, and reagent synthesis where both thermal and mechanical input must be precisely decoupled and controlled.
Key Features
- StirTrac™ intelligent magnetic coupling system for enhanced low-speed stability and high-torque consistency across the full 60–1200 rpm range
- Dual-mode temperature control: standard 1°C resolution; optional PT1000 probe enables 0.1°C resolution below 100°C and 1°C above 100°C for true sample temperature regulation
- HOT TOP™ real-time surface temperature warning: visual LED alert activates when top plate exceeds 50°C, mitigating operator burn risk during extended high-temperature operation
- Interchangeable ceramic (max 540°C) or aluminum (max 300°C) heating plates—7″ (178 mm) and 10″ (254 mm) formats support volumetric scalability from small-scale reaction vials to 6 L vessels
- Front-panel ergonomic design with raised bezel to prevent liquid ingress into controls during accidental spills or condensation
- Programmable timer (0–99:59 min or continuous mode) with auto-shutdown capability for unattended overnight experiments
- Integrated stainless-steel PT100 external temperature sensor, support rod, and universal clamp holder included as standard equipment
- High-contrast LED display showing simultaneous real-time values for speed (rpm), setpoint temperature (°C), and elapsed time
Sample Compatibility & Compliance
The SuperNuova+™ accommodates a broad spectrum of laboratory vessels—including borosilicate glass beakers, round-bottom flasks, crystallization dishes, and custom reaction blocks—without requiring modification or adapter kits. Its 11.3 kg (25 lbs) load capacity supports heavy-walled reactors and multi-vessel configurations. The instrument meets cCSAus and CE safety standards for electrical and thermal hazard mitigation. While not intrinsically rated for hazardous environments, its design aligns with GLP-compliant lab practices through traceable temperature calibration points, audit-ready timer logs (when used with external data capture), and configurable shutdown sequences. For regulated environments (e.g., USP , FDA 21 CFR Part 11), integration with validated third-party data acquisition systems enables electronic record generation with user authentication and change tracking.
Software & Data Management
The SuperNuova+™ operates as a standalone instrument with no embedded firmware-based software stack; all control logic resides in hardened microcontroller firmware compliant with IEC 61508 SIL-2 functional safety principles. Data output is limited to real-time analog signals from the integrated PT100 sensor and digital RPM feedback—enabling connection to external DAQ systems (e.g., LabVIEW, MATLAB, or LIMS platforms) via optional analog voltage outputs (0–10 V) or RS-232/USB interfaces (available via accessory module). No proprietary cloud services or vendor-hosted software dependencies are required. All calibration parameters—including offset correction for plate center vs. edge variance—are accessible and adjustable by authorized service personnel using factory-provided diagnostic tools, ensuring long-term metrological traceability per ISO/IEC 17025 requirements.
Applications
- Pharmaceutical process development: dissolution testing under USP Apparatus II conditions, buffer preparation, and API crystallization kinetics
- Chemical synthesis: Grignard reactions, esterifications, and polymerizations requiring precise thermal ramping and inert-atmosphere compatibility
- Biotechnology: cell culture media warming and pH-buffer equilibration prior to inoculation
- Materials science: nanoparticle dispersion in high-viscosity solvents, ceramic slurry homogenization, and composite precursor mixing
- Quality control labs: standardized viscosity benchmarking (per ASTM D2196), extractables/leachables sample prep, and reference standard reconstitution
FAQ
What is the difference between the SP88857195, SP88850195, and SP88857198 models?
The model numbers denote variations in plate material (ceramic vs. aluminum), diameter (7″ vs. 10″), and maximum operating temperature—SP88857195 is a 7″ ceramic plate unit rated to 540°C; SP88850195 is a 7″ aluminum variant (300°C max); SP88857198 is the 10″ ceramic configuration (400°C max).
Can the SuperNuova+™ be used for applications requiring GLP-compliant temperature validation?
Yes—when paired with a NIST-traceable PT1000 probe and external calibrated DAQ system, users may generate audit-ready temperature logs meeting GLP documentation standards. Factory calibration certificates are provided with each unit.
Is the StirTrac™ technology compatible with PTFE-coated stir bars in aggressive solvents?
StirTrac™ does not alter magnetic field geometry—it enhances torque fidelity. Standard PTFE- or glass-coated stir bars (e.g., Thermo Fisher catalog #12-510-12) remain fully compatible and recommended for organic solvent use.
Does the unit support external temperature feedback for closed-loop control?
Yes—the built-in PT100 sensor provides real-time plate temperature; an optional PT1000 probe (sold separately) enables direct sample temperature measurement and active feedback to the controller for tighter thermal regulation.
What maintenance is required to sustain accuracy over the 3-year warranty period?
No scheduled maintenance is required. Users should periodically verify plate temperature uniformity using a calibrated infrared thermometer or contact probe at three radial positions; cleaning with non-abrasive ethanol wipes is sufficient for routine decontamination.
