DRETOP JCY-1012 Magnetic Stirring Oil Bath

Overview

The DRETOP JCY-1012 Magnetic Stirring Oil Bath is a dual-function laboratory instrument engineered for precise thermal control and homogeneous mixing of samples in high-boiling-point or thermally sensitive applications. It operates on the principle of electromagnetic coupling—where a rotating magnetic field generated by an internal stator drives a PTFE-coated magnetic stir bar immersed in the sample—while simultaneously maintaining temperature uniformity via immersion-type resistive heating elements embedded within a stainless-steel oil bath chamber. Unlike conventional hotplates or water baths, this unit integrates both functions into a single compact platform with independent control over heating and stirring parameters. Its extended operating range up to 300°C makes it suitable for reactions requiring elevated temperatures without solvent evaporation or thermal degradation—particularly where water-based media would boil or decompose. The system is widely deployed in synthetic organic chemistry, polymerization studies, catalyst testing, pharmaceutical stability trials, and food-grade thermal processing validation.

Key Features

• Microprocessor-based PID temperature controller with dual digital display: real-time bath temperature and user-setpoint shown simultaneously on a backlit LCD interface
• High-stability thermal architecture featuring multi-layer insulated chamber walls, stainless-steel inner tank (304 grade), and electrophoretic epoxy-coated exterior for corrosion resistance
• Dual independent stirring stations, each supporting up to 2000 mL volume, with continuous 0–2400 rpm speed adjustment and LED digital speed readout
• Integrated drain valve for rapid, spill-free medium replacement—critical when switching between water and high-viscosity silicone oils
• Auto-recovery function preserves setpoints and timer values after power interruption; configurable over-temperature alarm with audible and visual alert
• PTFE/magnet composite stir bars rated for continuous operation at ≥300°C, resistant to strong acids, alkalis, and organic solvents
• Heating elements arranged in annular configuration beneath the bath floor to ensure radial thermal symmetry and minimize axial gradients

Sample Compatibility & Compliance

The JCY-1012 accommodates standard laboratory glassware including round-bottom flasks (up to 2 L), beakers, and jacketed reactors. Its open-bath design allows direct insertion of condensers, thermocouples, or inert gas inlets. As a Class I electrical appliance conforming to IEC 61010-1 safety standards, it includes earth leakage protection, thermal cut-off fuses, and dielectric insulation tested to 1500 V AC. For regulated environments, the device supports traceable calibration documentation aligned with ISO/IEC 17025 requirements. While not inherently 21 CFR Part 11 compliant, its stable analog control loop and non-networked architecture enable integration into validated workflows under GMP/GLP protocols—especially when paired with external data loggers meeting FDA audit criteria.

Software & Data Management

The JCY-1012 operates as a standalone hardware platform with no embedded firmware or network connectivity. All operational parameters—including temperature setpoint, ramp rate, hold time, and stirring speed—are configured manually via front-panel membrane switches. Calibration certificates (NIST-traceable sensor verification) are available upon request. Users may connect optional external USB or RS-485 data loggers (e.g., Omega OM-DAQPRO series) to record time-stamped temperature and RPM traces for regulatory submission. The instrument’s deterministic analog control loop ensures repeatable thermal profiles across multiple runs—essential for method transfer and inter-laboratory reproducibility.

Applications

• Controlled-temperature esterification and transesterification reactions in biodiesel synthesis
• Thermal aging studies of lubricants and insulating oils per ASTM D2440 and IEC 60296
• Preparation of nanoparticle dispersions requiring prolonged heating under inert atmosphere
• Standardized dissolution testing of solid dosage forms using USP Apparatus II (paddle) adaptations
• Enzymatic assays requiring strict thermal management during kinetic profiling
• Calibration of reference thermometers and RTDs in metrology laboratories

FAQ

Can the JCY-1012 be used with water instead of oil?

Yes—though only within the 5–100°C range. Water must be replaced regularly to prevent scaling and microbial growth; use deionized water for optimal thermal consistency.
Is the bath depth customizable beyond 100 mm?

Yes. DRETOP offers OEM customization for chamber depths up to 200 mm to accommodate taller vessels; lead time increases by 3–4 weeks.
Does the unit support external temperature probe feedback?

No—the built-in Pt100 sensor measures bath temperature only. For sample-core temperature monitoring, users must integrate a separate probe with external PID controller.
What maintenance is required for long-term reliability?

Annual inspection of heater element continuity, stir motor brush wear (if applicable), and seal integrity around the drain valve is recommended. Avoid immersion of the control panel in humid environments.
Are spare stir bars and oil bath media supplied by DRETOP?

Yes. PTFE-encapsulated stir bars (Φ10 × 30 mm, Φ15 × 40 mm) and certified silicone heat-transfer fluids (350 cSt, 1000 cSt) are stocked and shipped globally.
