Overview
The StableTemp 04802-13 Precision Magnetic Hotplate Stirrer is an engineered laboratory platform designed for simultaneous precise heating and magnetic stirring of samples in glass or stainless-steel vessels. Utilizing a robust cast-aluminum heating plate with uniform thermal conductivity and a high-efficiency permanent-magnet drive system, it delivers consistent torque across the full speed range while maintaining stable temperature setpoints via PID-controlled solid-state heating. Its dual-display interface independently monitors actual and setpoint temperature (±1 °C accuracy typical) and real-time rotational speed (±2 rpm resolution), enabling reproducible experimental conditions essential for method development, quality control, and regulatory-compliant workflows in pharmaceutical, chemical, and materials research laboratories.
Key Features
- Microprocessor-based control system ensuring precise regulation of both temperature (30–540 °C) and stirring speed (30–1200 rpm) across the entire operating range
- Dual LED display showing simultaneous readouts of setpoint temperature, actual plate temperature, and current stirring speed—critical for process validation and SOP adherence
- Splash-resistant two-piece cast-aluminum housing with contoured base geometry to divert spilled liquids away from internal electronics and motor assembly
- Integrated support rod mounting bracket with thumb-screw fastening, accommodating rods up to 13 mm in diameter for secure attachment of sensors, condensers, or pH electrodes
- Over-temperature protection circuitry automatically cuts power if surface temperature exceeds safe operational limits, safeguarding both sample integrity and user safety
- Visual hot-surface indicator remains illuminated whenever plate temperature exceeds 50 °C—compliant with ANSI Z535.4 hazard communication standards
- Programmable timer function with audible alert and automatic heating shutoff, supporting unattended operation under defined thermal protocols
Sample Compatibility & Compliance
The 04802-13 accommodates standard laboratory glassware including Griffin beakers (50–1000 mL), Erlenmeyer flasks (50–1000 mL), and cylindrical reaction vessels—compatible with borosilicate glass, quartz, and PTFE-lined containers. Its 31 × 31 cm aluminum heating surface ensures uniform thermal distribution (±3 °C variation across surface at 300 °C), validated per ASTM E220 for thermal uniformity testing. The device meets IEC 61010-1:2010 safety requirements for laboratory electrical equipment and incorporates design elements aligned with GLP and GMP documentation practices—including non-volatile parameter storage and audit-ready operational logging when used with optional data acquisition software.
Software & Data Management
While the 04802-13 operates as a standalone instrument, its analog output ports (0–5 V for temperature, 0–10 V for speed) enable integration with third-party data loggers or SCADA systems for continuous monitoring. When paired with StableTemp’s optional LabLink™ software suite (sold separately), users gain access to time-stamped parameter export (CSV), calibration certificate generation, electronic signature support compliant with FDA 21 CFR Part 11, and configurable alarm thresholds. All firmware updates are delivered via USB interface and retain full traceability of version history and installation timestamps.
Applications
- Controlled-temperature dissolution testing in pharmaceutical QC labs (aligned with USP and )
- Homogeneous catalyst dispersion during synthetic organic reactions requiring inert-atmosphere compatibility
- Viscosity-temperature profiling of polymer solutions and colloidal suspensions
- Standardized buffer preparation and reagent aging studies under ISO/IEC 17025-accredited conditions
- Preparative-scale crystallization experiments where nucleation onset correlates strongly with thermal ramp rate and mixing homogeneity
- Environmental sample digestion protocols (e.g., EPA Method 3050B) requiring precise ramp-and-hold thermal profiles
FAQ
Does the 04802-13 support external temperature feedback control using the included probe?
Yes—the PTFE-coated stainless steel probe connects to the rear-panel input port and enables closed-loop temperature regulation based on solution temperature rather than plate surface temperature.
Is the unit compatible with corrosive solvents such as concentrated HNO₃ or HF?
The aluminum heating plate is not chemically resistant to strong mineral acids; use only with acid-resistant ceramic-top variants (e.g., model 03407-05) when handling aggressive reagents.
Can the stirring speed and temperature be programmed in sequence (e.g., ramp then hold)?
No—this model does not feature multi-step program capability; it maintains fixed setpoints. For programmable ramps, consider the StableTemp 04803-17 series with embedded profile editor.
What is the maximum recommended vessel height for stable stirring performance?
For optimal vortex formation and magnetic coupling, vessel height should not exceed 1.5× the internal diameter; taller vessels require higher stir bar aspect ratios and reduced speed settings.
Is calibration documentation provided with shipment?
Each unit ships with a factory-issued Certificate of Conformance; NIST-traceable calibration certificates are available upon request at time of order.
