A line of low temperature coolers provide rapid, low cost cooling of liquids to temperatures as low as -100°C. Available in both immersion probe and flow-through styles, these compact systems are suitable for cooling exothermic reactions, freeze point determinations, freeze drying, impact testing, lyophilization, and vapour and solvent trapping. Also suitable for trapping, Dewar-type applications, and the rapid cool down of small volumes of liquids, the Immersion Probe Style Coolers reduce the expense of using dry ice or liquid nitrogen. A flexible hose allows convenient placement of the cooling probe. Seven different models as well as a variety of probe types are available.
