How do I order items?

If you need to have an order placed, start with our online purchase request system, Aestiva, at purchasing.chem.wisc.edu.

  • You will need to have a chemistry account in order to gain access.
  • If you have never used the system, but have a chemistry account, send a request to Chad Skemp at cskemp@chem.wisc.edu with the following information:
  1. Full name
  2. Email (name@wisc.edu or name@chem.wisc.edu)
  3. Research group
  4. Phone number (so purchasing staff can contact you with questions about your request)

General Purchasing Guidelines

For purchases under $5,000: We can normally approve and process these requests without needing anything additional from the requestor. There may occasionally be other barriers, such as the intended vendor being prohibited by the university, but this is rare. For questions on purchases in this area, contact Chad Skemp, purchasing specialist, at 608.262.1481.

For purchases from $5,000 to $49,999, we require one of the following:

  1. That the vendor and the items being purchased already be on contract with the university. Search vendors currently on contract.
  2. Simplified Bid: Three comparative quotes, from which the lowest responsible quote is chosen to make the purchase; or
  3. Proper justification to waive the need for the simplified bid/three quotes, submitted on the Non-Competitive Purchase Request Form (.doc).*

*Non-Competitive Waivers over $25,000 require a governor’s waiver, which is very time-consuming and often unnecessary. In these cases, it generally makes most sense to prepare the simplified bid. If three relevant vendors are contacted, but two of the three cannot provide the requested items with required specifications, those two still count as bids.

For purchases of $50,000 or more: Purchasing Services will prepare an Official Sealed Bid or a Request for Proposal (RFP) depending upon the type of items and/or services needed. 

Our main contact for these is Jeff Whitman, jwhitman@bussvc.wisc.edu.
