Revvity Fresh Lot Schedule



Consistent with UW-3043, all non-exempt radioactive material should be ordered by the Office of Radiation Safety through, and delivered to, the Central Ordering Receiving and Distribution (CORD) office.  There are special circumstances when material may be ordered or delivered outside of this process, but that requires special arrangements ahead of time.  To order radionuclides you must be assigned an authorized RAM user by your respective PI. Requisitions are collected between 12:00-12:30 PM.  Requisitions made after noon will generally be placed the next day.


With the exception of special events and holidays, CORD is staffed Monday through Friday during regular business hours.  Radioactive material deliveries are delivered to the CORD lab for check in consistent with DOT regulations and addition to the EHSA inventory.  Every effort is made to deliver material to labs within a few hours of receipt.  All deliveries of licensed radioactive material require a signature from a trained radiation worker that is knowledgeable about the storage requirements of the specific material.  There are no weekend deliveries.  We cannot guarantee shipping times and are often at the mercy of our shipping partners

Inventory and Requisition Numbers

The Requisition number is often similar to the vial’s inventory number.  The requisition number is created at the time you request an order be placed.  The inventory number is created once the order has been received and receipted by CORD.  Please be aware of which number you are using.


CORD will place orders to the vendor of your choice.  It should be noted that contracted vendors (some of those listed below) generally the lowest prices. If you choose a non-contract vendor, you must supply the CORD office the contact information such as vendor name, item number, web address and/or phone number.
