Hanuo SC-60A Advanced Circulating Constant-Temperature Bath

Overview

The Hanuo SC-60A Advanced Circulating Constant-Temperature Bath is a precision-engineered thermal control system designed for laboratories requiring stable, uniform, and programmable temperature environments across extended operational durations. Operating on the principle of forced convection via integrated circulation pumps, the SC-60A maintains thermal equilibrium through continuous fluid recirculation—either internally within the bath chamber or externally to auxiliary equipment such as reaction jackets, viscometers, or spectroscopic cells. Unlike basic heating mantles or immersion heaters, this unit delivers high spatial uniformity (±0.1 °C typical gradient across working volume) and temporal stability (±0.2 °C over 8 hours), meeting calibration-grade requirements for thermometric standardization in metrology labs and instrument qualification workflows. Its dual-mode compatibility with water (up to 95 °C) and silicone/heat-transfer oils (up to 200 °C) enables flexible deployment across biological incubation, polymer rheology, pharmaceutical dissolution testing, and materials science thermal aging protocols.

Key Features

• Compact desktop architecture optimized for benchtop space efficiency without compromising thermal performance or accessibility.
• Robust stainless-steel bath chamber with corrosion-resistant finish and reinforced insulation to minimize heat loss and improve energy efficiency.
• PID-based digital temperature controller with auto-tuning capability ensures rapid thermal equilibration and sustained setpoint accuracy under dynamic load conditions.
• Dual LED display simultaneously indicates real-time measured temperature and user-defined setpoint, with tactile membrane keypad interface for intuitive operation.
• Integrated dual-circulation system: internal recirculation enhances thermal homogeneity; external port supports flow rates up to 12 L/min (with optional pump upgrade) for closed-loop temperature control of external apparatus.
• Modular design accommodates retrofit integration of an external chiller unit—enabling active cooling during exothermic reactions or post-heating quenching cycles without bath replacement.

Sample Compatibility & Compliance

The SC-60A accommodates a wide range of sample containers—including glass flasks (up to 5 L), jacketed reactors, rotary evaporator condensers, and custom thermal probes—within its 60 L working volume (approx. 400 × 330 × 450 mm internal dimensions). The unit complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). While not certified for GMP manufacturing environments, its repeatable thermal performance supports GLP-compliant data generation when operated within documented SOPs. Traceable calibration using NIST-traceable reference thermometers is recommended prior to critical applications such as USP environmental monitoring or ISO 17025-accredited viscosity calibration.

Software & Data Management

The SC-60A operates as a standalone analog/digital hybrid system with no built-in data logging or PC connectivity. However, its analog output (0–5 V or 4–20 mA, configurable) enables seamless integration with third-party data acquisition systems (e.g., LabVIEW, MATLAB, or industrial SCADA platforms) for time-stamped temperature trending, alarm triggering, and audit-ready record retention. When deployed in regulated environments, users may implement manual logbooks or electronic lab notebooks (ELNs) compliant with FDA 21 CFR Part 11 requirements—provided metadata (operator ID, timestamp, deviation notes) is captured contemporaneously with each setpoint change or maintenance action.

Applications

• Calibration of liquid-in-glass thermometers, RTDs, and thermocouples against primary standards.
• Thermal conditioning of samples prior to DSC, TGA, or DMA analysis to eliminate thermal history effects.
• Temperature stabilization of optical components in interferometry or laser alignment setups where thermal drift compromises resolution.
• Controlled heating of reagent solutions in synthetic chemistry workflows requiring precise endothermic ramp profiles.
• Long-term thermal stress testing of electronic components, adhesives, and packaging materials per ASTM D3418 or ISO 294-4 protocols.
• Supporting enzymatic assays in molecular biology labs where activity is highly sensitive to sub-degree fluctuations.

FAQ

Is the SC-60A suitable for use with organic solvents?
No. The bath is designed exclusively for water and approved heat-transfer oils (e.g., Dow Corning PMX-200 series). Organic solvents may degrade seals, compromise pump integrity, or pose fire hazards above their flash points.
Can the external circulation port be used for both heating and cooling?
The SC-60A provides only heating functionality. For bidirectional thermal control, an external chiller must be connected in series with the circulation loop.
What is the maximum allowable viscosity for external circulation?
For optimal pump performance and thermal transfer efficiency, fluids with kinematic viscosity below 100 cSt at operating temperature are recommended.
Does the unit include a drain valve for maintenance?
Yes—a front-mounted brass drain valve facilitates complete fluid evacuation during oil changes or seasonal storage.
Is RS-232 or USB communication available?
Not natively. Communication requires optional analog-to-digital interface modules or third-party signal conditioners compatible with the unit’s analog output port.
