Thermo Scientific Cimarec Series Hotplate Stirrer

Overview

The Thermo Scientific™ Cimarec™ Series Hotplate Stirrer is an engineered solution for precise, reproducible heating and magnetic stirring in research, quality control, and teaching laboratories. Designed around a robust ceramic or aluminum heating plate architecture, the system delivers uniform thermal distribution across the entire surface—enabling rapid, stable sample warming without hot spots. Its operation is grounded in electromagnetic induction principles: a rotating magnetic field generated beneath the plate couples with ferromagnetic stir bars immersed in vessels, driving consistent rotational motion while minimizing mechanical wear. The unit integrates digital temperature control with discrete 5°C setpoint increments and real-time display, supporting applications from gentle dissolution at 5°C to high-temperature reflux at 540°C (models with ceramic plates). All variants comply with IEC 61010-1 safety standards for laboratory electrical equipment and are constructed to meet long-term operational demands under GLP and ISO 17025-aligned workflows.

Key Features

• StirTrac™ Technology: Dynamically adjusts magnetic field strength to maintain constant stir speed across varying viscosity, vessel geometry, and load mass—ensuring laminar mixing performance even during exothermic reactions or solvent evaporation.
• HOT TOP Surface Alert System: Automatically activates a visual indicator when plate surface temperature exceeds 50°C, providing tactile and visual feedback to prevent accidental contact burns—a critical safeguard in shared lab environments.
• Instant Stop Function: Halts stir bar rotation immediately upon vessel removal, eliminating uncontrolled motion that could cause splashing, spillage, or damage to sensitive samples or glassware.
• Three Platform Configurations: Available in 4″, 7″, and 10″ (10.8 cm, 18.4 cm, and 26.0 cm square) formats—each optimized for distinct throughput requirements: 1 L, 4 L, or 6 L maximum vessel capacity, respectively.
• Dual-Material Heating Options: Ceramic plates offer superior chemical resistance and thermal stability up to 540°C; aluminum variants provide faster thermal response and cost-effective performance up to 400°C (10″ models).
• Compact, Low-Profile Chassis: Engineered for benchtop stability with reinforced base geometry and non-slip rubber feet—minimizing vibration transmission during high-speed stirring (up to 1200 rpm).

Sample Compatibility & Compliance

The Cimarec Series accommodates standard laboratory glassware including beakers, Erlenmeyer flasks, round-bottom flasks, and jacketed reactors—compatible with borosilicate glass, PTFE-coated stir bars, and chemically resistant vessel liners. It supports routine validation protocols required under FDA 21 CFR Part 11 for electronic records, when integrated with compliant LIMS or ELN systems via external data logging. Units are certified to UL/CSA 61010-1 and CE-marked for EMC and low-voltage directive compliance. No internal battery or wireless module is present, ensuring electromagnetic compatibility in proximity to sensitive instrumentation such as NMR spectrometers or mass spectrometers.

Software & Data Management

The Cimarec Series operates as a standalone analog-digital hybrid instrument with no embedded firmware update capability or cloud connectivity. Temperature and speed parameters are set manually via front-panel rotary controls and displayed on a high-contrast LED screen. For traceable process documentation, users may employ external USB or RS-232 data loggers (e.g., Omega OM-DAQPRO series) to capture time-stamped temperature/stir speed profiles. Audit trails generated through such loggers satisfy GLP requirements for method validation, calibration verification, and deviation reporting. The device does not store historical data internally nor support password-protected user accounts—consistent with its role as a dedicated, deterministic benchtop tool rather than a networked analytical platform.

Applications

• Controlled-temperature dissolution of polymers, APIs, and excipients in pharmaceutical development (aligned with USP & Ph. Eur. dissolution testing guidelines).
• Precipitation and crystallization studies requiring isothermal hold conditions over extended durations (e.g., 24–72 h).
• Preparation of homogeneous catalyst slurries and nanoparticle dispersions where shear-sensitive agglomeration must be avoided.
• Standardized buffer and reagent preparation in clinical diagnostics labs operating under CLIA and CAP accreditation frameworks.
• Teaching laboratory demonstrations of Arrhenius kinetics, reaction enthalpy estimation, and heat transfer fundamentals.
• Supporting ASTM D2156 (soot content in fuels) and ASTM D86 (distillation range) sample conditioning steps.

FAQ

What is the maximum recommended operating temperature for the 10-inch Cimarec model?
The 10-inch Cimarec hotplate stirrer with ceramic plate is rated for continuous operation up to 400°C; models with smaller platforms support up to 540°C.
Can the Cimarec Series be used with closed-vessel systems such as sealed pressure tubes?
Yes—provided the vessel material is compatible with the selected temperature and the stir bar remains magnetically coupled; however, pressure containment must be ensured externally, as the unit itself provides no pressure rating.
Is calibration documentation included with shipment?
Factory calibration certificates are available upon request at time of order; users are responsible for periodic verification per ISO/IEC 17025 Clause 6.5 using NIST-traceable thermometers and tachometers.
Does the unit support programmable ramp-soak temperature profiles?
No—the Cimarec Series features manual setpoint control only; for automated thermal profiling, integration with external PID controllers or programmable ovens is required.
Are replacement stir bars and ceramic plates available as spare parts?
Yes—Thermo Fisher offers genuine OEM stir bars (PTFE-coated, AlNiCo, and SmCo variants) and field-replaceable ceramic heating modules under part numbers accessible via the Thermo Fisher Online Parts Catalog.
