DRY ICE 4K for Mossbauer
The DRY ICE 4K Cryostat for Mossbauer experiments where quick sample changes are vital. The system is loaded with a probe which cools the sample through exchange gas. Changing the sample simply requires removing the probe, changing the sample and then re-inserting the probe. This changeover can be completed in as little as 2 hours (4K to 300K back to 4K).
This cryostat has been used for a variety of applications including; pre-screening samples for dilution fridges, ESR, Mossbauer and general electrical properties measurements.
