CCG-1.5K series closed-cycle thermostat with closed-cycle chiller, built-in heaters and sensors and external temperature controller to achieve the low temperature thermostat temperature change and temperature control.CCG-1.5K series of closed-cycle thermostat can provide a continuous temperature change from 1.5K to 325K, which is a great convenience for the low-temperature scientific experiments.

  The CCG-1.5K is designed with a top loading and unloading sample rod, which allows for quick sample changes without having to return the entire system to room temperature when a sample change is required. The sample chamber is completely cooled by the exchange gas (helium), making it easy to cool samples such as liquids and powders that are not easily cooled. In order to meet the electrical testing needs of customers, the cryostat can be configured with a variety of electrical leads (e.g. Ph-Br wires, coaxial and triaxial cables, etc.), resistor holders, or probe holders according to the experimental needs. The thermostats are available in optical configurations and support a wide range of user-selectable window materials to meet a wide spectral range of tests from far/mid infrared, UV to X-ray.

Features:
- Wide temperature range: 1.5 K to 325 K
- Samples in static exchange atmosphere
- Large sample space with a wide range of holders for testing a wide range of thin film, bulk, powder and liquid samples.
- Aluminium vacuum enclosure and radiation shield with segmented design for quick sample changes
- Optical enclosure with 4 optical windows as standard (38mm) or non-optical vacuum enclosure. 
- Temperature control system
- Supports standard optical, powder, liquid, resistive, probe and resistive sample holders.
- Sample chamber with top loading and unloading lever design for easy sample change.
- Vacuum enclosure with pre-drilled blind for optional electrical measurement configurations (e.g. SMA, BNC, triple coaxial, multi-pin electrical vacuum feed-through phosphor bronze, very fine coaxial, semi-rigid microwave cables, etc.)
- Optional optical configurations add optical windows with appropriate window materials to meet a wide spectral range of tests from far/mid infrared, UV to X-ray.
