The Avantgarde CCG-1.5K series of closed-cycle thermostats with closed-cycle chiller, built-in heaters and sensors work in conjunction with an external thermostat to provide variable temperature and temperature control of the cryostat.The CCG-1.5K series of closed-cycle thermostats provide continuous temperature change from 1.5K to 325K, making them a convenient choice for low-temperature scientific experiments.
The CCG-1.5K is designed with a top loading sample rod, which allows for quick sample changes without having to return the entire system to room temperature when sample changes are required.The sample chamber is completely cooled by the exchange gas (helium), making it easy to cool samples such as liquids and powders, which 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, depending on the needs of the experiment. The thermostat can be configured with optional optics and supports a variety of user-selected window materials to meet a wide spectral range of tests from far/mid infrared, UV to X-ray.

System Features:

- Wide temperature range: 1.5 K to 325 K
- Samples in static exchange atmosphere
- Large sample space with a variety of sample holders for testing a wide range of thin films, bulk, powder and liquid samples
- Aluminum vacuum enclosure and radiation shield with segmented design for quick sample changes
- Optical housing with 4 optical windows (38mm) or non-optical vacuum housing as standard. 
- Temperature control system
- Supports standard optical, powder, liquid, resistive, probe and resistive sample holders, with a wide range of holders available.
- The sample chamber is designed with a top loading and unloading lever for easy sample change.
- Vacuum enclosure with pre-drilled blind for a variety of electrical measurement configurations (e.g. SMA, BNC, tri-coaxial, multi-needle electrical vacuum-fed phosphor-copper wire, very fine coaxial wire, semi-rigid microwave cable, etc.)
- Optional optical configurations to add optical windows, with appropriate window materials, to meet a wide spectral range of tests from far/mid IR, UV to X-ray
