PT Top Loader
The PT Top Loader is a top-loading dry cryostat that is well suited for a variety of measurements and utilizes the latest low vibration pulse tube technology. This solution can be used in various optical and non-optical setups. The top loading nature allows the sample to be exchanged without warming up the entire cryostat. It also boasts extremely fast sample cool-down: It takes less than 10 minutes for a single sample to cool from 300 K to 4 K, and less than 20 minutes for a multiple sample holder of e. g. 12 samples. This cryostat can also be fully customized to meet your individual needs.
