Neta/Sigma Collaboration – Effective in Penn Marketplace Monday, August 29, 2022

Neta Scientific and Sigma Aldrich, Inc. have developed a partnership making Neta Scientific the Tier1 contract holder for Sigma products on campus. This collaboration combines the strengths of one of world’s largest distributors of research chemicals and a long-standing, successful, regional, minority and woman-owned supplier to the University. Under this new structure and effective Monday, August 29, 2022, all Sigma-Aldrich, Inc. products will be sourced and distributed through the new Neta/Sigma (BEN # 650531) collaboration in the Penn Marketplace. Sigma-Aldrich, Inc. will no longer be a sourcing option in the Penn Marketplace.  The Neta/Sigma punchout will still feature all the functionality that is available on the current Sigma Aldrich, Inc. punchout.

Please note this applies only to the products historically distributed by Sigma Aldrich, Inc.  Neta Scientific (BEN# 423478) will remain available for all other products which Neta has previously provided. Questions about products and service offerings should be directed to the applicable representative below, while questions about the supplier relationship with Penn can be sent to Michael Talley, the sourcing manager responsible for the Research & Life Sciences category.
