Lake Shore — environment by JANIS

Lake Shore has a full range of 4 K closed cycle cryostats, including both bottom loading (sample in vacuum) and top loading (sample in exchange gas) designs. With a wide range of electrical feedthrough and window options and designs for specific applications such as Mössbauer spectroscopy, a Lake Shore 4 K CCR is a versatile choice for making measurements down to 4 K without using liquid helium.
