CT4-Pro 4°C Thermostatic Ice Box
Microprocessor-controlled 4°C thermostatic ice box utilizing high-efficiency Peltier cooling technology to rapidly chill and maintain samples at 4°C within 10 minutes. Ideal for molecular biology, PCR prep, electrophoresis, and enzyme preservation.
Constant 4°C Temperature | Fast Cooling (≤10 min to 4°C) | Peltier Precision Control (±0.5°C) | Magnetic Adsorption Blocks
Key Features
- Fast Cooling Rate: Drops from room temperature to 4°C in approximately 10 minutes, maintaining sample viability without melting ice.
- Peltier Precision Control: High-efficiency thermoelectric Peltier element delivers accurate temperature control (±0.5°C) and excellent homogeneity.
- Dual-Color Status LED: Multi-color LEDs (Red/Green) clearly indicate cooling and steady-state operating modes.
- Magnetic Adsorption Blocks: Quick-change magnetic block mounting allows instant block replacement without tools.
- Continuous Operation: Engineered for continuous non-stop running with quiet operation (≤55 dB).
- Built-In Module Reminder: Integrated module sensing and safety reminders for reliable operation.
Applications
Widely used for biological sample preservation, pre-denaturation of DNA amplification products, electrophoresis preparation, serum coagulation, restriction enzyme storage, and reagent chilling across pharmaceutical, food safety, and environmental testing labs.
