✦ Synopsis
Balzer's freeze-etch machine cold stage modification
The cold stage specimen surface in our Balzer's 300 Freezeetch instrument, averages 29-43°C warmer than the reading on the GA-1 stage temperature control unit. By introduction of Indium foil seals above and below the stainless steel plug in the stage tower, the specimen cold stage surface temperatures were still 9-10°C warmer than the GA-1 reading. After replacing the stainless steel plug with a copper plug and using Indium seals, the cold stage specimen surface was brought within 2.6"C of the GA-1 temperature reading. In addition, the copper plug, Indium seal modified stage cools about two times faster in going from -100°C to -150°C than the normal stainless steel stage modified with Indium seals.
