Cryogenic Precision Heating Cooling Stage Reaching -190°C ±0.1°C Stability Anti-Frost System Polymer Research

The GoGo CH400-CRS Cryogenic Precision Heating Cooling Stage is purpose-engineered for laboratories where sub-ambient temperature stability defines experimental success. Achieving and maintaining -190°C with a remarkable ±0.1°C stability, this Heating Cooling Stage provides the thermal foundation for the most demanding cryogenic microscopy applications. From polymer glass transition temperature (Tg) determination to liquid crystal phase behavior analysis and biological specimen cryopreservation studies, the CH400-CRS delivers the precise thermal environment that cryogenic research demands.

What sets this Heating Cooling Stage apart is its integrated anti-frost system, a critical feature for extended low-temperature operation. The gas purge attachment continuously delivers a controlled flow of dry nitrogen across the observation windows, effectively eliminating condensation and ice crystal formation that would otherwise obscure optical access. This enables uninterrupted multi-hour cryogenic experiments without the need to interrupt protocols for manual defrosting, a common limitation of conventional stages that severely compromises experimental continuity and data quality.

The CH400-CRS employs an optimized liquid nitrogen cooling circuit with precision flow control, achieving controlled cooling rates of 40°C per minute while maintaining exceptional temperature uniformity across the entire 23mm × 23mm silver sample holder. The intelligent TNEX control platform includes a dedicated cryogenic protocol library with pre-configured ramp-and-hold sequences for common polymer characterization workflows, dramatically reducing setup time and ensuring reproducibility across experimental runs.

• -190°C Cryogenic Capability: Optimized liquid nitrogen cooling circuit achieves and reliably maintains extreme low temperatures for hours of continuous operation, making it ideal for polymer Tg analysis and cryogenic phase transition research.
• Active Anti-Frost Defrosting: Integrated gas purge system continuously supplies dry nitrogen flow across observation windows, preventing condensation and ice formation during extended sub-ambient experiments without interrupting data collection.
• ±0.1°C Ultra-Stable Control: Precision PID temperature regulation maintains setpoint stability within one-tenth of a degree, essential for detecting subtle thermal events such as secondary phase transitions and glass transition phenomena.
• TNEX Cryogenic Protocol Library: Pre-configured thermal cycling sequences for standard polymer characterization methods reduce experiment setup time and ensure protocol reproducibility across multiple users and laboratory sessions.
• Multi-Spectral Window Compatibility: JGS2 fused silica observation windows transmit from 220nm through 2500nm, enabling simultaneous UV, visible, and IR imaging during cryogenic experiments.
• Compact and Versatile Mounting: The 86mm × 100mm × 21.5mm form factor and 0.6kg weight allow rapid installation on standard upright and inverted microscopes as well as spectrometer sample compartments.

The CH400-CRS Cryogenic Heating Cooling Stage addresses the specialized requirements of research groups focused on low-temperature material behavior. Polymer scientists rely on it for precise glass transition temperature (Tg) determination, crystallization kinetics studies, and viscoelastic property characterization across the cryogenic range. In the pharmaceutical industry, it supports lyophilization process development and frozen-state formulation stability testing. Liquid crystal research laboratories benefit from the exceptional temperature stability for precise phase transition temperature mapping. Biological and biomedical researchers use the stage for cryopreservation protocol optimization, ice recrystallization inhibition studies, and cold-adapted protein behavior observation. Food science laboratories employ it for freeze-thaw cycle analysis and frozen state microstructure characterization. The anti-frost system makes this Heating Cooling Stage particularly valuable for facilities in high-humidity environments where conventional cryogenic stages frequently suffer from window fogging, including research centers across Southeast Asia, the Middle East, and tropical climate regions.

Every CH400-CRS Heating Cooling Stage undergoes rigorous factory acceptance testing including a 72-hour cryogenic endurance test at -190°C, temperature stability verification across the full operational range, and optical path clarity certification under condensing humidity conditions.
