1 Liquid Nitrogen Research Dewars Sample in Vacuum: Detector Series Industries of America

2 Sample in Vacuum Detector Series UNIQUE THERMAL LINK DESIGN VARIABLE TEMPERATURE LIQUID NITROGEN RESEARCH DEWARS The Detector cryostats are equipped with an adjustable thermal link built into the liquid nitrogen reservoir. This link is a controlled variable thermal resistance between the liquid cryogen and the cold pedestal. Thermal isolation becomes single gas phase resulting in exceptional variable temperature operation. A unique design featuring: Full range variable temperature, <77 to 325K Pumpable LN2 reservoir for operation at temperatures down to less than 65K Test IR Focal Plane Arrays, ICs (DIPs), Detectors... standard and custom devices support for (14-64-pin DIP, pin LCCs) Up to 244 signal lines Variable Temperature Stability +/- 0.05K Cold finger (pedestal) sample in vacuum Small - hand held - cryostat design Very stable temperatures Eliminates common problems: no flow control difficulties, no capillary or flow line to freeze/plug, no reservoir pressure regulation required, no exchange gas required Easy quick pour fill - refill of liquid nitrogen while holding set temperature auto fill option for virtual unlimited run time Optional configurations with multiple sample pedestals (cold fingers) in one cryostat - each pedestal individually temperature controlled Brings variable temperature to production work - pour fill and press the temperature control button; - it s that easy. No experience required. Industries of America, Inc S. Willow St. Manchester, NH 03103
