It is a harris cryostat made by International Equipment Co. Can't find squat online about this Model CT, just later harris models that aren't close to the style of this one. I'll check the compressor and see if it still works. Doubting that it will cool anymore, but I may be able to solve that problem with dry ice.
Does anyone have any information about this old cryostat we found? Our lab does neurological research and is willing to use it if salvageable. Pictures are below. What I have found so far is this ad (http://pubs.acs.org/doi/pdfplus/10.1021/ac60186a877), so this seems like a rather old piece of equipment. Has blades and all. Looking for an instruction manual really, but can't seem to locate one on the interweb. Any help is much appreciated!
