Overview
The Cole-Parmer Stuart SHP-200D-S Digital Heating Magnetic Stirrer is an engineered solution for precise, reproducible mixing and temperature-controlled sample preparation in research laboratories, quality control environments, and educational institutions. Designed around the principle of magnetic coupling—where a rotating permanent magnet beneath the work surface induces synchronous rotation of a PTFE-coated stir bar immersed in the sample—the instrument delivers consistent agitation without mechanical shaft penetration. Integrated resistive heating elements provide uniform thermal distribution across the ceramic-coated aluminum plate, enabling simultaneous stirring and heating within a controlled thermal envelope. This dual-function architecture supports applications requiring strict thermal management, such as dissolution testing, buffer equilibration, enzymatic reactions, and reagent synthesis where viscosity, volatility, or sensitivity to contamination preclude overhead stirring.
Key Features
- Digital LED display showing real-time setpoints and actual values for both speed (0–1,200 rpm) and plate temperature (room temperature to 300°C), with ±1°C thermal accuracy and ±5 rpm speed resolution
- Ceramic-coated aluminum heating plate offering chemical resistance, rapid thermal response, and uniform heat distribution over 130 mm diameter working area
- Brushless DC motor ensuring low-noise operation, extended service life, and minimal torque fluctuation across the full speed range
- Programmable ramping function for controlled heating profiles, supporting method-defined thermal protocols
- Overheat protection circuitry automatically deactivates heating if surface temperature exceeds safe operational limits, complying with IEC 61010-1 safety standards
- Compact benchtop footprint (220 × 160 × 95 mm) with non-slip rubber feet and integrated cable management slot
Sample Compatibility & Compliance
The SHP-200D-S accommodates standard laboratory vessels including glass beakers (up to 2 L capacity), Erlenmeyer flasks, and cylindrical reaction tubes—provided stir bar geometry and sample volume allow stable vortex formation. Its sealed electronics and corrosion-resistant housing meet IP21 ingress protection requirements. The instrument conforms to key international laboratory safety and performance standards, including UL 61010-1 (North America), CE marking under the EU Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU), and is suitable for use in GLP-compliant workflows where equipment qualification (IQ/OQ) documentation is maintained. While not inherently 21 CFR Part 11 compliant, audit trails for temperature and speed settings can be manually recorded per SOPs for regulated environments.
Software & Data Management
The SHP-200D-S operates as a standalone analog-digital hybrid controller with no embedded firmware or network interface. All parameter inputs and status feedback occur via front-panel push buttons and the dual-line LED display. No proprietary software, drivers, or cloud connectivity are required—ensuring long-term operational continuity and minimizing cybersecurity exposure. For laboratories implementing electronic lab notebooks (ELNs) or LIMS integration, external data loggers (e.g., USB thermocouple interfaces or RS-232-enabled chart recorders) may be used to capture time-stamped temperature and speed profiles, provided they comply with local validation requirements.
Applications
- Buffer and media preparation in molecular biology and cell culture labs
- Accelerated solvent extraction (ASE) pre-heating stages
- Standardization of viscosity reference fluids prior to rheometer calibration
- Homogenization of nanoparticle suspensions in materials science workflows
- Controlled heating/stirring during Karl Fischer titration sample conditioning
- Teaching laboratory demonstrations of Arrhenius kinetics and thermal stability thresholds
FAQ
What is the maximum recommended vessel size for optimal stirring performance?
For consistent vortex formation and thermal uniformity, use containers ≤2 L with flat-bottom geometry; larger volumes require verification of stir bar size and rotational inertia.
Can the SHP-200D-S be used with corrosive solvents such as concentrated acids or halogenated organics?
The ceramic-coated plate resists mild corrosion, but direct contact with strong oxidizers (e.g., fuming nitric acid) or molten alkalis is not advised; always consult chemical compatibility charts for PTFE-coated stir bars.
Is external calibration traceable to NIST standards supported?
Yes—temperature calibration can be verified using a NIST-traceable RTD probe placed on the plate surface; speed calibration requires optical tachometry per ASTM E2877-22 guidelines.
Does the unit support continuous operation at 300°C?
Sustained operation above 250°C is discouraged due to accelerated thermal aging of internal components; intermittent use up to 300°C is permissible with adequate cooling intervals.
How is maintenance performed on the motor and heating assembly?
No user-serviceable parts exist inside the chassis; routine cleaning with isopropyl alcohol and lint-free cloth suffices—do not disassemble or apply lubricants to moving components.
