DEREGISTRATION OF SECURITIES

This Post-Effective Amendment (the “Post-Effective Amendment”) relates to the Registration Statement on Form S-3, Registration No. 333-155275, (the “Registration Statement”) pertaining to the registration of an indeterminate amount of debt securities, common stock, preferred stock, depositary shares, warrants, securities issuable upon exchange or conversion of debt securities, preferred stock, depositary shares, and warrants, and rights to purchase participating preferred stock of Beckman Coulter, Inc. (the “Company”), which was originally filed with the Securities and Exchange Commission on November 12, 2008.

On February 6, 2011, the Company entered into an Agreement and Plan of Merger with Danaher Corporation, a Delaware corporation (“Danaher”), and Djanet Acquisition Corp., which, at the time, was a Delaware corporation and an indirect wholly-owned subsidiary of Danaher (“Merger Sub”) (such agreement, the “Merger Agreement”), pursuant to which Merger Sub was merged with and into the Company, and the Company became an indirect wholly-owned subsidiary of Danaher on June 30, 2011 (the “Merger”).

In connection with the Merger, the Company has terminated any offering of the Company’s securities pursuant to its existing registration statements, including the Registration Statement. In accordance with an undertaking made by the Company in Part II of the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance that remain unsold at the termination of the offering, the Company hereby removes from registration all of such securities of the Company registered under the Registration Statement that remain unsold as of the date of this Post-Effective Amendment.
