Series V. Scientific Products, Incorporated (SPI) Files, 1959-1991, undated

Scientific Products, Incorporated (SPI) was an American scientific instrument leasing and finance company. Incorporated in 1960 and based in State College, Pennsylvania, SPI mainly focused on leasing scientific instruments manufactured by Nuclide Corporation. SPI also purchased, reconditioned, and sold used scientific instruments built by Nuclide and other scientific instrument firms. Later in its existence, the firm provided financing and equipment to Nuclide Corporation and its successor Measurement and Analysis Systems, Incorporated (MAAS), which allowed them to complete their customers’ orders. SPI was renamed Science Centre, Incorporated in 1988.

Although it was a separate firm, SPI maintained a close relationship with Nuclide and MAAS throughout its existence. Leonard F. Herzog served as SPI’s president from 1969 to 1979.
