The FLV-80 continuous flow thermostat provides temperature control in the range of 4K to 450K (liquid helium) and 78K to 450K (liquid nitrogen)，In order to meet the customer's electrical testing needs，The AOV-FL cryostat can be configured with various electrical leads according to experimental needs，Such as Ph-Br line, coaxial cable and triple coaxial cable，And there are different types of sample seats to choose from，Such as optical sample base, resistance sample base, probe sample base, liquid sample base and powder sample base。
The thermostat comes standard with four transparent fused quartz Windows with transmission wavelengths ranging from ultraviolet to near-infrared, and other window materials can be selected to meet the wide spectrum range of tests from far/mid-infrared, ultraviolet to X-ray。Thermostat built-in heater and high-precision temperature sensor, through the supporting transmission pipeline, liquid nitrogen/liquid helium dewar, the continuous flow of refrigerant (liquid helium or liquid nitrogen) evaporation heat absorption as a cold source to reduce the temperature of the sample seat, with the external temperature control instrument to achieve accurate temperature control of the low-temperature thermostat。
System features:
• Wide temperature range: from 4K to 450K, decompression and cooling up to ~2K
• The sample is cooled by heat conduction in a vacuum
• Large sample space, can be paired with a variety of sample types to test a variety of film, block, powder and liquid samples
• Low refrigerant consumption, using liquid helium to drop from room temperature to 5K requires only 0.4L liquid helium, using liquid nitrogen to keep 80K consumption at 0.1L/h
• Standard 4 optical Windows with a viewing range of 38mm
• Equipped with temperature control system
• Support standard optical sample base, powder sample base, liquid sample base, resistance sample base, probe sample base and resistance sample base, a variety of sample base to choose from
• The sample room adopts quick-discharge clamp design for easy sample replacement
• Small size for easy integration into commercial spectrometer equipment
