Low-vibration top-loading 4K closed-cycle thermostat CCG-4K12-LV

The CCG-4K12-LV low-vibration top sample loading 4K closed-cycle thermostat is equipped with a closed-cycle refrigeration machine, built-in heater and sensor. It needs to be used in conjunction with an external temperature controller to achieve temperature variation and control. Both the refrigeration machine and the sample rod adopt a vibration-reducing structure design, with a vibration level better than ±1 micron. It can provide continuous temperature variation from 4K to 300K. It has provided great convenience for low-temperature scientific experiments. The CCG-4K12-LV adopts a top sample loading and unloading rod design, which facilitates rapid sample change when it is necessary without having to return the entire system to room temperature. The sample chamber is completely in the exchange gas (helium) for more uniform cooling, which is convenient for cooling liquid, powder and other samples that are difficult to cool. To meet the electrical testing requirements of customers, the low-temperature thermostat can be equipped with various electrical leads (such as Ph-Br wires, coaxial cables and triple coaxial cables, etc.), resistance sample holders or probe sample holders according to the experimental needs.
