The FLV-80M micro-miniature continuous flow thermostat allows variable temperature and temperature control in the temperature range of 4K~450K (liquid helium) and 78K~450K (liquid nitrogen). The sample chamber has a separate cover that allows for quick opening of the chamber when sample changes are required. In order to meet customers' electrical testing needs, 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 experimental needs. The thermostat comes standard with top and bottom clear fused silica windows transmitting wavelengths from the UV to the NIR, and other window materials are available to meet a wide spectral range of tests from the far/medium infrared, UV to X-ray.

  Micro thermostats are specifically designed for microscopy, imaging and high spatial resolution photoluminescence. Typical applications include spectroscopic testing (PL spectroscopy, FTIR and UV-Visible), electrical testing (conductivity, Hall effect) as well as cryogenic imaging, microscopy and component testing. The special construction of the cryostat provides a short working distance (for use with high magnification optical systems) for easy mounting on common microscope stages and panning tables.

Features:
- Wide temperature range: from 4K to 450K, with decompression down to ~2K.
- Short working distance: with different sample holders, the sample can be wirelessly approached to the window.
- Samples are cooled in a vacuum by thermal conduction.
- Compact sample space design for electrical or microscopic experiments requiring high working distances.
- 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 is required to maintain 80K.
- Standardly equipped with 2 optical windows with a viewing range of 25mm.
- Equipped with temperature control system
- Supports standard optical, probe and resistive sample holders, with a wide range of holders available.
- Sample chamber with separate lid for easy sample changing
- Compact size for easy integration into commercial spectrometer equipment
