Ladies and Gentlemen:

We have been engaged as special legal counsel in the State of Florida for Sovereign Scientific, LLC, a Florida limited liability company (“Guarantor”), in connection with the Guarantor’s proposed guarantee under the Indenture (as defined below) of exchange notes in an aggregate principal amount of $750,000,000 (the “Exchange Notes”) to be issued by VWR Funding, Inc., a Delaware corporation (the “Company”) in connection with an exchange offer to be made pursuant to a Registration Statement on Form S-4 (such Registration Statement, as supplemented or amended, is hereinafter referred to as the “Registration Statement”) to be filed with the United States Securities and Exchange Commission on or about April 4, 2013, under the Securities Act of 1933, as amended (the “Act”), and the rules and regulations thereunder (the “Rules”). The obligations of the Company under the Exchange Notes will be guaranteed by the Guarantor (the guarantee by the Guarantor of each of the Exchange Notes, collectively, the “Guarantee”). The Exchange Notes and the Guarantee are to be issued pursuant to the Indenture, dated as of September 4, 2012 (as may be amended or supplemented from time to time, the “Indenture”), among the Company and the guarantors named therein, including, without limitation, the Guarantor. This opinion is issued at your request.

In arriving at the opinions expressed below, we have examined and relied on an original or copy, identified to our satisfaction, of the following documents (collectively, the “Transaction Documents”):

1. The Indenture;

2. The form of Note Guarantee attached as Exhibit B to the Indenture;

3. The Registration Rights Agreement dated as of September 4, 2012 (the Registration Rights Agreement”), among the Company, the Guarantors, and the initial Purchasers named therein;

4. the Written Consent in Lieu of a Special Meeting of the Board of Managers of the Guarantor, dated as of December 3, 2012, with respect to the execution of the Indenture and the issuance of the Guarantee;

5. the Written Consent in Lieu of a Special Meeting of the Board of Managers of the Guarantor, dated as of April 4, 2013, with respect to the Exchange Notes and Guarantee; and

6. The Registration Statement.

In addition, we have examined such other documents and limited liability company records (collectively, the “Other Documents”) and such questions of law as we have deemed necessary or appropriate for the purposes of this opinion. As to facts material to our opinion, we have made no independent investigation of such facts and have relied on such certificates from officers and representatives of the Guarantor, and from public officials, as we have deemed necessary or appropriate for the basis of this opinion. In making the foregoing examinations, we have assumed that, as to the factual matters, all representations and warranties and other factual statements made in the Transaction Documents and Other Documents (other than those which are expressed herein as our opinions) were and are true, correct and complete in all material respects, and we made no independent investigation of such matters. We have assumed that any representation or statement qualified by “the best of knowledge” of the party making such representation or statement, or by similar qualification, is correct without such qualification (other than those which are expressed herein as our opinions). As to all matters in which a person or entity making a representation referred to above has represented that such person or entity either is not a party to, or does not have, or is not aware of, any plan or intention, understanding or agreement, we have assumed that there is in fact no such plan, intention, understanding or agreement. Moreover, to the extent that any of the Other Documents is governed by the laws of any jurisdiction other than the jurisdictions that are the subject of this opinion, our opinion relating to those Other Documents is based solely upon the plain meaning of their language without regard to interpretation or construction that might be indicated by the laws governing those Other Documents.

In rendering the opinions herein set forth, we have assumed, with your permission and without independent investigation on our part, the following:

(i) each of the Other Documents has been duly authorized, executed and delivered by each of the parties thereto, that each such party has the requisite power and authority to execute, deliver and perform the Other Documents and that the Other Documents constitute the legal, valid and binding obligation of each such party thereto enforceable against it in accordance with its terms;

(ii) the Transaction Documents (other than the Guaranty) have been duly authorized by each of the parties thereto, that each such party has the requisite power and authority to execute, deliver and perform the Transaction Documents (other than the Guaranty) to which it is a party, that the Transaction Documents (other than the Guaranty) have been duly executed and delivered by each of the parties thereto, that the Transaction Documents constitute the legal, valid and binding obligations of each party thereto enforceable in accordance with their terms, and that the Transaction Documents have not been amended, restated, released, terminated or cancelled;

(iii) the legal capacity of natural persons;

(iv) that the laws of any jurisdiction other than the jurisdictions that are the subject of this opinion do not affect the terms of the Transaction Documents;

(v) there are no extrinsic agreements or understandings among the parties to the Transaction Documents that would modify or affect the interpretation of the terms of the Transaction Documents or the respective rights or obligations of the parties thereunder;

(vi) that each party to the Transaction Documents has received adequate consideration under applicable law for its execution and delivery thereof; and

(vii) all documents submitted to us as originals are authentic, all documents submitted to us as certified or photostatic copies conform to the authentic original documents, all signatures on all documents submitted to us for examination are genuine, the Transaction Documents will be executed in the form reviewed, and all public records reviewed are accurate and complete.

Based upon the foregoing, and in reliance thereon, and subject to the assumptions, qualifications, exceptions and limitations set forth herein, we are of the opinion as of the Effective Date (as defined in the Registration Statement), having due regard for such legal consideration as we deem relevant, that:

1. The Guarantor is a limited liability company, validly existing and in good standing under the laws of the State of Florida. This opinion is based solely upon the Certificate of Status relating to the Guarantor issued by the Secretary of State of the State of Florida dated April 3, 2013. Such opinion is limited to the meanings ascribed to such certificate.

2. The Guarantor:

(a) has the requisite limited liability company power and authority (i) to execute and deliver the Indenture and the Guarantee, and (ii) to perform its obligations under the Indenture and the Guarantee;

(b) has taken the limited liability company action necessary to authorize the execution and delivery of, and performance of its agreements in, the Indenture and the Guarantee; and

(c) has duly executed and delivered the Indenture and Guarantee.

(a) violate the Articles of Organization or the Operating Agreement of the Guarantor; or

(b) violate any Applicable Laws (defined below).

4. The issuance by the Guarantor of the Guarantee does not require any Government Approvals (defined below), except such as may be required under Securities Act or the Securities Exchange Act of 1934, and any rules or regulations adopted thereunder, or any state “blue sky” or similar laws, in each case as amended.
