JanisULT designs and builds refrigerators for operation below 1 K with a focus on quantum technology applications.
We offer the widest range of helium-3 refrigerators and dilution refrigerators available on the market. Whatever your application, whether you prefer a traditional cryogenic solution or a cryogen-free design, we probably already have a design that suits you, and if not then we will customize a solution for your specific needs.
We are the market leaders in UHV compatible solutions for surface science.
High-performance cryogen-free dilution refrigerators for Quantum Science are developed in conjunction with Google.
The JanisULT product range includes helium-3 and dilution refrigerators for ultra-low temperature applications. Both types of refrigerators are available cooled using liquid cryogens (wet), using closed-cycle coolers (dry), and are available in UHV or other custom designs.
Since 1961 JanisULT (previously known as Janis Research Company) has been providing the scientific and technical community with the highest-quality cryogenic equipment for research, characterization, and industrial applications. In August 2020 JanisULT sold their laboratory cryogenics business to Lake Shore Cryotronics. JanisULT is now focused on ultra-low temperature solutions based on helium-3 and dilution refrigerators. Over the years, our family of customers has grown to include some of the world’s largest corporations and best-known research centers and institutions. The reasons for this record of success are simple: precision engineering and quality manufacturing; ease-of-operation; day-after-day reliability and performance; and a level of service and support unmatched in the industry. JanisULT recognizes that obtaining an ultra-low temperature cryogenic system represents a long-term commitment for most scientists; therefore, we are devoted to providing you with the highest level of quality and customer support. Just a few of the ways we accomplish this are:
- Sales and service are provided through a worldwide network of trained and knowledgeable representatives
- A dedicated Janis Research sales engineer is responsible for each system from conceptual design through post-installation support
- A stable workforce draws on decades of combined service, and applies this experience to the assembly of each cryogenic system
- Customer approval of the final design drawing is obtained for all customized systems
- Records on all systems, modifications and design improvements are meticulously maintained for the reference of any future user
- Turnkey systems are supplied by offering a full line of cryogenic accessories
- Each system is fully integrated and tested before shipping
