Laboratory supply purchases are normally initiated only by the authorized purchasers for each laboratory. The purchaser must be able to show that each purchase is a reasonable expense that is appropriately allocated for the project(s) and funding source(s). Each purchasing transaction must be signed by the Principle Investigator (Responsible Person) or the Designated Authorizer for the account from which the purchase is made.

How do we get that?

  • Order Request Form (See Forms & Links Page)
  • PCard - University issued credit card. BME & HOGL each hold a Department Card for use by infrequent purchasers as approved by the PI. The PCard may be used for purchases of lab supplies, conference registration fees and other daily expenditures. Some items may not be purchased using the PCard. These items are listed Here
    • Utilizing a PCard is a privilege, not a right. It is the responsibility of the PCard holder to compile a PCard document packet for each and every transaction that includes:
      • PCard Form
      • Invoice- must accurately reflect the amount charged
      • Packing slip
  • Purchase Order - Traditional method of ordering items through a requisition process. POs must be used to make all capital purchases (over $5K) and purchases where a paper check is required. Other purchases that may require a PO include annual contracts for goods or for service and, in rare instances, travel or conference expenses. POs are initiated by Renee.

Tax Exemptions

While most purchases made by the University are not exempt from sales tax, certain equipment and chemical purchases may qualify for exemptions.

  • Scientific Equipment - Durable equipment used for basic or applied scientific research may be eligible for a sales tax exemption under Arizona tax laws. Equipment does not necessarily have to meet the threshold for a captial equipment purchase to quailify for a sales tax exemption. Additionally, computers that meet the definition may also be exempt from sales tax. All tax-exempt equipment purchases must be initiated through the Division Office.
  • Chemicals - Liquid, solid or gaseous chemicals used in research and development may be exempt from sales tax under Arizona law. To obtain this exemption, chemical orders should be placed separately from other research supply orders. Instructions for placing chemical orders in order to qualify for the tax exemption may be found here.
ARL BME purchasing procedures follow University of Arizona Expenditure Policies and Procedures (FRS Manual 10.0) and ARL Purchasing Policy.
