Oxford OptistatDry

Oxford OptistatDry BLV is a bottom-loading cryostat for spectroscopy consists of a compact cryostat with optical access, cooled by a closed-cycle refrigerator. This cryogen free cryostat is capable of cooling samples to under 5 K without the need for liquid cryogens. This provides significant benefits in terms of ease of use and running costs when compared to non-closed-cycle liquid He cryostats. This cryostat enables optical and electrical measurements.
