TERMINATION OF OFFERING

On December 20, 2002, Apogent Technologies Inc. and certain of its subsidiaries as guarantors (collectively, the “Registrants”) filed a registration statement on Form S-3 (No. 333-102101), (as amended by Pre-Effective Amendment No. 1 filed on January 10, 2003, the “Registration Statement”), which registered for resale by the selling holders 2.25% Senior Convertible Contingent Debt Securities (“CODES”) due 2021 and the common stock, $0.01 par value per share, with attached preferred stock purchase rights, issuable upon conversion thereof (“Shares”).* The Registrants’ contractual obligation to maintain the effectiveness of the Registration Statement has expired. Accordingly, pursuant to the undertaking contained in the Registration Statement, the Registrants are filing this Post-Effective Amendment No. 1 to terminate the Registration Statement and to remove from registration all of the CODES and Shares that were registered in the Offering but remain unsold as of the date hereof, calculated to be $85,901,000 principal amount of CODES and 2,817,167 Shares issuable upon conversion thereof.

Accordingly, the Registrants are filing this Post-Effective Amendment No. 1 to deregister such CODES and Shares covered by the Registration Statement that remain unsold as of the date hereof.

*The Registration Statement was filed to add additional Apogent subsidiaries as guarantors of the CODES, and replaced the earlier resale registration statement filed with respect to the CODES and the Shares, Registration Statement on Form S-3,  No. 333-75834, as amended. All of the remaining unsold securities covered by Registration No. 333-75834 were deemed deregistered upon the offset of the filing fee applicable to such unsold securities against the filing fee for the Registration Statement.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933 and Rule 478(a) thereunder, this amendment to the registration statement has been signed by the agent for service named in the registration statement in the City of Portsmouth, State of New Hampshire, on October 27, 2003.
