Purchase Orders for Research Supplies


In order to streamline Science Program purchase order procedures, a standard operating procedure for the ordering of research laboratory supplies is essential.  This procedure is designed to guarantee all chemicals and supplies are received through a central location.  This will ensure Safety Data Sheets (SDS) are obtained prior to ordering, chemicals and supplies are logged into the inventory and materials are properly handled and stored.


This procedure applies to all principal investigators and student researchers who need to order research laboratory supplies.

  6. The LM will submit the PO requisition to Fiscal Affairs (Purchasing Agent/Grants Accountant) for processing and assignment of a PO number.
  7. Purchasing will return the completed PO to the LM, who will review the document for errors.
