AELAB CT4-Pro 4°C Thermostatic Ice Box | Precision Laboratory Cooling System

The AELAB CT4-Pro 4°C Thermostatic Ice Box is a high-precision, microcomputer-controlled cooling instrument designed for reliable sample preservation and temperature-sensitive laboratory workflows. This thermostatic ice box offers rapid cooling performance, exceptional temperature uniformity, and intelligent LED status indicators, ensuring consistent 4°C control for demanding laboratory environments.

The AELAB CT4-Pro 4°C Thermostatic Ice Box uses advanced Peltier thermoelectric cooling technology to maintain a stable 4°C environment. Its microcomputer regulation system continuously adjusts temperature to guarantee uniform cooling across all samples. With interchangeable magnetic adsorption modules, the CT4-Pro thermostatic ice box supports various tube formats, while the LED dual-colour indicators offer clear, real-time operational feedback.

⚙️ Design & Construction

The AELAB CT4-Pro features a compact benchtop structure engineered for stable thermal performance. Its Peltier thermoelectric system eliminates the need for refrigerants and enables rapid cooling from room temperature to 4°C. The housing integrates a clear front display with LED dual-colour indicators (Red & Green) for immediate system status. Magnetic adsorption allows quick replacement of tube modules, supporting a wide range of laboratory formats while maintaining precise thermal contact.

🔬 Working Principle / Testing Method

The CT4-Pro regulates temperature through high-efficiency Peltier elements controlled by a microcomputer feedback loop. The system monitors internal temperature accuracy to ±0.5°C and maintains uniformity within ±0.5°C across the cooling surface. Once activated, the unit cools to 4°C within ≤10 minutes depending on the installed module. Continuous-run capability supports extended workflows such as sample stabilization, electrophoresis preparation, or pre-denaturation cooling.
