SPECTROSCOPY
Cryo-Tip® Refrigerators: inexpensive solutions to difficult cryogenic interfaces. • Temperatures down to 3.6° Κ • Temperature control to ± 0 . 1 ° Κ • Uses gaseous, not liquid, helium. • Wide variety of interfaces available. A single Cryo-Tip^ Refrigerator serves many operations simply by changing the inexpensive vacuum shroud interface. These refrigerators operate by the Joule-Thomson expansion of economi cal, convenient cylinder gas, eliminat ing the need for liquid helium. Gives precise temperature control from 3.6° Κ to 300° Κ by simply varying gas pressure. Cryo-Tip refrigerators are now used for low-temperature experiments in UV, IR, visible and nuclear spectroscopy — with interfaces for many makes of spectrometers. Other uses include x-ray diffraction, Hall effects, field-ion mi croscopy, semiconductor studies, ESR, EPR, NMR and cooling of lasers and low-noise receivers. Available for open- or closed-cycle "plug-in" operation. For full technical information, write: Advanced Products Dept., Air Products & Chemicals, Inc., Box 538, Allentown, Pa. 18105.
