INFORMATION ABOUT OUR BUSINESS 

LabRatParts is the Ebay division of Scientific Instrumentation Services. We are a professional Transmission Electron Microscope service, restoration and sales company. We have been working with Electron Microscopes since the early 80's. We also restore/repair other instrumentation and equipment.  If we do not have the time to diagnose a problem or the components to get something running again we often strip it down for parts.  All our listings are negotiable as far as price goes, and what is available for sale. Need just one part from a listing? Let us know.  We have no intention of selling anyone something that does not work, but we cannot test everything. We have many parts for Philips, FEI, JEOL, ZEISS TEMS/SEMS that we do not list. If you need a part for one...please ask.
