Dry Micro
The Dry Micro is a versatile, compact, and robust closed cycle cryostat that can be used in various optical and non-optical setups. The Dry Micro cryostat has a built-in liquefier that transfers liquid helium directly to the sample holder. The helium is then cleaned and recondensed in a continuous process. The use of a small, highly effective heat exchanger allows these cryostats to be extremely compact in size and enables users to apply them in almost any imaginable configuration and orientation. The product also boasts an incredibly broad operating temperature range, from approx. 5 K to 500 K or higher, depending on the configuration. The system is also designed to handle low thermal drift and contraction and ultra-low vibrations.
