Overview
The Titan HCC-4005 is a high-stability, dual-function precision circulating bath engineered for simultaneous temperature control and magnetic stirring in laboratory-scale reaction systems. It operates on a closed-loop refrigeration-heating thermodynamic cycle, integrating a high-efficiency compressor-based cooling system with Peltier-assisted fine-tuning and PID-controlled resistive heating. Unlike conventional water or oil baths, the HCC-4005 employs a stainless-steel circulation chamber with integrated stir bar drive—enabling uniform thermal distribution and consistent agitation without external stirrers or mechanical couplings. Its operational range spans from −40 °C to +40 °C, making it suitable for low-temperature catalysis, cryogenic synthesis, enzyme kinetics studies, and controlled crystallization protocols where both thermal stability and mechanical homogeneity are critical.
Key Features
- Integrated magnetic stirring mechanism with adjustable speed (0–1,200 rpm), driven by a brushless DC motor beneath the bath plate for zero vibration transmission and long-term reliability.
- Triple-tier temperature accuracy selection (±0.1 °C / ±0.01 °C / ±0.001 °C) achieved through factory-calibrated Pt1000 sensor arrays and real-time drift compensation algorithms.
- Programmable ramp-soak profiles with up to 10 segment sequences; ramp time configurable from minutes to 999 hours 59 minutes for extended kinetic experiments.
- Stainless-steel 316L circulation chamber (capacity: 5.5 L) with corrosion-resistant fluid path and leak-proof sealing—compatible with aqueous, ethylene glycol, and silicone oil heat transfer media.
- Front-panel 5.6-inch TFT-LCD touchscreen with multilingual UI (English, German, French, Chinese), real-time graphing of temperature/stir speed, and password-protected parameter locking.
- RS485 communication interface supporting Modbus RTU protocol for integration into centralized lab automation systems or LIMS environments.
Sample Compatibility & Compliance
The HCC-4005 accommodates standard laboratory glassware including jacketed reactors (up to 2 L volume), round-bottom flasks (50–1,000 mL), and custom reactor vessels with external cooling jackets. Its uniform temperature field (±0.2 °C spatial deviation across 100 mm diameter at setpoint) meets ASTM E2777-22 requirements for thermal uniformity in controlled environment equipment. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking under the EU Low Voltage and EMC Directives. Optional IQ/OQ documentation packages are available for GLP and GMP-regulated laboratories requiring traceable validation per FDA 21 CFR Part 11 guidelines.
Software & Data Management
Titan provides the optional TitanLink Control Suite (v3.2+), a Windows-based application enabling remote monitoring, data logging at user-defined intervals (100 ms–30 min), and export to CSV, Excel, or PDF formats. Audit trail functionality records all parameter changes, user logins, and alarm events with timestamp and operator ID—supporting ALCOA+ data integrity principles. Raw sensor data is stored locally on an internal SD card (8 GB preinstalled) with automatic rollover and encryption (AES-256). Firmware updates are performed via USB or network connection, with version rollback capability for regulatory continuity.
Applications
- Low-temperature Grignard and organolithium reactions requiring strict −30 °C to −10 °C control with continuous mixing.
- Enzyme activity assays where thermal drift >0.05 °C directly impacts Vmax and Km reproducibility.
- Polymorph screening via controlled cooling crystallization with programmable descent rates (e.g., −0.1 °C/min).
- Calibration of reference thermometers and thermocouples against NIST-traceable standards.
- Pre-conditioning of samples prior to DSC, TGA, or rheological analysis to ensure thermal equilibration.
FAQ
What heat transfer fluids are recommended for operation below −20 °C?
Ethylene glycol/water mixtures (60/40 v/v) or low-viscosity silicone oils (e.g., Dow Corning PMX-200, 10 cSt) are validated for full-range performance. Avoid aqueous solutions below −5 °C without antifreeze.
Does the HCC-4005 support external temperature probe feedback control?
Yes—via optional PT100 input port; enables jacket or reactor wall temperature control independent of bath fluid temperature.
Is the unit compatible with hazardous area classifications (e.g., ATEX)?
No—the HCC-4005 is rated for general laboratory use only (Class I, Division 2 not applicable); explosion-proof variants are not offered.
Can multiple units be synchronized for parallel reaction blocks?
Yes—using RS485 daisy-chaining and TitanLink’s master-slave configuration mode, up to 16 units can share ramp profiles and trigger coordinated start/stop events.
What maintenance intervals are specified for compressor service?
Compressor oil and filter replacement is required every 12,000 operating hours or 36 months, whichever occurs first; service logs are auto-recorded in the system memory.
