Model 103 RapidCool Pulse-tube ADR cryostat
< 4K in < 4 hours

The 103 RapidCool Cryostat (RCC) accelerates cooldown from room temperature to 4 K in just 4 hours (compared to a typical cooldown time of 13 hours). The 103 RapidCool provides all of the benefits of our popular 103 Rainier cryostat, and also allows you to expedite your experimentation, without delay. You get the best of all worlds: a compact, cylindrical cryostat with a large experimental space; plus, super-fast liquid nitrogen cooldown and insulated inlet/outlet lines that prevent frost formation. In addition, our RapidCool features can be used as options on other HPD cryostat models. Call us to discuss your needs.
