The SPI Supplies Division of Structure Probe, Inc. was started in 1975 and is now known worldwide as a leading manufacturer and distributor of sample preparation equipment and consumable supply items for the routine operation of the typical SEM, TEM, LM, SPM and surface analysis laboratory. We also provide service including analytic services, laboratory services, claims Substantiation, and Failure Analysis. The SPI Supplies website has become the world's "reference resource" for information about microscopy sample preparation and equipment maintenance items. We are also known as the innovator in our corner of the microscopy and microanalysis market, being the first to bring to commercial realization now familiar products such as colloidal gold probes and silicon nitride membrane window grids. Perhaps most importantly, with our own in-house SEM and TEM capabilities, we can quality inspect our products before final packaging. We can duplicate customer problems and give them solutions. No other firm serving our end of the microscopy and microanalysis market can come close to providing such a high level service.
