HCS621G/V Gas/Vacuum-Tight Hot & Cold Stages
Instec’s HCS621 series vacuum and gas-tight stages are designed for applications where a wide temperature range is needed and control over the atmosphere is critical. This series features a silver heating and cooling block, providing the user with exceptional temperature uniformity. The gas-tight configuration provides a sealed chamber for gas purge to avoid condensation or oxidation. The vacuum-tight models can be both gas purged and evacuated to low pressures to protect sensitive samples from moisture and oxygen and to study vacuum processes such as freeze drying. Options are available including X-Y sample positioning, and up to 8 electric feedthroughs for sample connection and probing.
 
High performance across a very large temperature range.
