The Avantgarde FLV-80 continuous flow thermostat can realize precise temperature change and temperature control in the temperature range of 4K~450K (liquid helium) and 78K~450K (liquid nitrogen). In order to satisfy the needs of customers for electrical testing, the AOV-FL cryostat can be configured with various kinds of electrical leads, such as Ph-Br wires, coaxial cables, and triple-coaxial cables according to the needs of experiments, and different types of sample holders are available, such as optical sample holders, resistive sample holders, probe sample holders, liquid sample holders and powder sample holders. Different types of sample holders are available, such as optical sample holders, resistive sample holders, probe sample holders, liquid sample holders and powder sample holders.

The thermostat comes standard with a four-way transparent fused silica window that transmits wavelengths from the UV to the NIR, while other window materials are available to cover a wide spectral range from the far/medium infrared, UV to X-rays. The thermostat is equipped with a built-in heater and a high precision temperature sensor. The liquid nitrogen/liquid helium dewars are used to reduce the temperature of the sample holder by evaporating and absorbing the heat from the continuously flowing refrigerant (liquid helium or liquid nitrogen) as a cold source through the supporting transmission lines and liquid nitrogen/liquid helium dewars, which are used together with the external temperature controller to realize the precise temperature change and control of the cryostat.

System Features:

- Wide temperature range: from 4K to 450K, with depressurization down to ~2K.
- Samples are cooled by heat transfer in vacuum.
- Large sample space with a variety of sample holders for testing a wide range of film, bulk, powder and liquid samples.
- Low refrigerant consumption, only 0.4L of liquid helium is required to reduce the temperature from room to 5K, and 0.1L/h of liquid nitrogen to maintain 80K.
- Standardly equipped with 4 optical windows with a viewing range of 38mm.
- Equipped with temperature control system
- Support standard optical sample holders, powder sample holders, liquid sample holders, resistance sample holders, probe sample holders and resistance sample holders, a variety of sample holders to choose from.
- Sample chamber with quick release clamps for easy sample replacement
- Compact size for easy integration into commercial spectrometer equipment
