Delegation of Signature Authority
In order to make purchases on a grant budget, the purchaser must be delegated signature authority by the Principal Investigator. The person to which signature authority has been delegated should have direct knowledge of the needs of the research project. Delegation must be made in writing or email to the Chemistry Purchasing and Accounting Office. The Purchasing and Accounting Office maintains files of these delegations to insure compliance with federal guidelines. Auditors frequently ask for proof of delegation of authority.
Principal Investigators may complete the form at the link below to delegate authority to research staff and students.
Completed forms should be sent to Elizabeth in the Purchasing and Accounting Office. Alternatively, PIs may send Elizabeth an email (firstname.lastname@example.org). However, it’s preferable to use the form.
Purchasing Process and Procedures
The Department of Chemistry has a central purchasing staff. They will place orders to outside vendors for you and will help you resolve any problems that may occur. Purchase requests are submitted to the Purchasing staff via PurchasePath. PurchasePath is a web-based ordering system that manages all aspects of purchasing including order submission, approval, receiving, and history. You can attach supporting documentation (quotes, sole source justifications, etc.) electronically to your PurchasePath order. PurchasePath is also used by the Chemistry purchasing staff to communicate with you concerning your order. If you need have any questions, please contact Elizabeth in the Purchasing and Accounting Office.
Paper Requests for Purchase – You may still submit requests for purchase using the paper forms. However, we strongly urge you to submit orders via PurchasePath. We’ve discontinued ordering the multi-copy paper forms.
If you do submit a paper form, the Purchasing staff will use it to create a PurchasePath order and will give you access to it. This assures that all orders are handled in the same manner, improves our internal tracking, and facilitates documentation.
Please be sure to be as specific as possible about when you need your material. This will help the purchasing staff prioritize work and assure that you get what you need, when you need it. Our goal is to place orders within one business day of receipt. For urgent orders, it would be advisable to contact either Adam or Mike directly after you’ve submitted the order in PurchasePath.

Orders over $10,000
The “direct buy limit” is $10,000. Orders over this amount are subject to state law requiring competitive pricing. The UW has established competitive contracts with many supplies. The direct buy limit does not apply to suppliers with which there is a competitive contract. If there is no competitive contract in place, you may be asked to complete a Sole Source justification. The Chemistry Purchasing and Accounting staff will help you with this requirement. Additional information is available here:
M & E Tax Sales Exemption (Machinery & Equipment)
If an equipment purchase meets certain criteria, the purchase may qualify for an M & E tax exemption, which would exempt the purchase from sales tax. These qualifications are:
Non- equipment costs (such as replacement parts) may also qualify for this exemption
More information if available here:
You will be asked to submit and M&E tax exemption form with your order.
The Chemistry Research Stockroom (Bagley 36) is the department’s central receiving area. All material will be shipped to Bagley 36. You will be notified via email when your shipment arrives. If you want to check the status of your shipment, please check with the Purchasing and Accounting Office.
For further information, please see the Shipping and Receiving policy.
Equipment is not automatically insured by the University. The UW Office of Risk Management administers an optional, low cost insurance plan for University owned equipment. If you’re interested in obtaining this coverage for your equipment, please contact Elizabeth.
