Standard Configuration

The model HE-3-TLSL-NMR is a top loading system with sample in liquid He-3. The cryostat has a compact design and fits typical existing NMR magnet systems with room temperature bore. The sample can be top-loaded into the He-3 chamber, while the cryostat stays cold. A sample probe and load-lock system is included, along with an external gas handling system for safe and quick sample insertion and removal in and out of the He-3 sample chamber.
