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:
