ALab™ CT4-Pro 4°C Thermostatic Ice Box
Product Detail
ALab™ CT4-Pro 4°C Thermostatic Ice Box — a microcomputer-controlled thermostat with Peltier temperature control: 4°C setting, ±0.5°C accuracy and uniformity, about 10 minutes from room temperature to 4°C.

The 4°C Thermostatic Ice Box is a microcomputer-controlled thermostat with high temperature control accuracy and good homogeneity, widely used for sample preservation, pre-denaturation of DNA amplification products and electrophoresis, serum coagulation, etc. The industry covers pharmaceutical, chemical, food safety and environmental testing. The CT4-Pro uses high-efficiency Peltier precision temperature control; it takes only about 10 minutes to reduce the temperature from room temperature to 4°C. Multi-colour LEDs indicate different operating status and a built-in module reminder function is provided. Multiple module choices, with easy replacement by magnetic adsorption, suit a wide range of test tubes and support continuous operation.
