SPI Supplies offers all its products on this website primarily for applications in research, testing and analysis, development work and education. These items are not being offered for clinical or diagnostic applications, agricultural uses or for human or animal consumption. Some products may have a "dual - use" purpose. We will determine on a case by case basis whether or not to accept an order. SPI Supplies reserves the right to make this determination. You may receive communications from our firm seeking additional information about intended use. We are only trying to behave as a responsible vendor during times when there is a growing number of "dual use" applications for some of our products.
