JANIS

Since 1961 Janis Research Company has been providing the scientific and technical community with the highest-quality cryogenic equipment for research, characterization, and industrial applications. 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.

Janis Research recognizes that obtaining a 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.

Liquid Helium, Liquid Nitrogen and Cryogen Free

Micro-manipulated Cryogenic & Vacuum Probe Systems for Chips, Wafers and Device Testing  from ~3.5 K to 675 K

Janis micromanipulated probe stations are designed for non-destructive electrical testing using DC, RF, and fiber-optic probes. They are useful in a variety of fields including semiconductors, MEMS, superconductivity, electronics, ferroelectrics, material science, physics and optics. Either LHe/LN2 or a mechanical closed cycle refrigerator provides cooling. Different models locate the sample in ultra-high vacuum (UHV), ultra-high temperature (to 675 K), and magnetic field.
