     RE:  Tech Laboratories,  Inc. (the "Corporation") Registration Statement on
          Form SB-2 (the "Registration Statement")

Gentlemen:

     We have  acted  as  counsel  to the  Corporation  in  connection  with  the
preparation of the Registration Statement filed with the Securities and Exchange
Commission  pursuant to the Securities Act of 1933, as amended (the "1933 Act"),
relating to the  proposed  public  offering of up to  189,492,704  shares of the
Corporation's Common Stock, par value $0.001 per share (the "Common Stock").

     We are furnishing  this opinion to you in accordance with Item 601(b)(5) of
Regulation S-B  promulgated  under the 1933 Act for filing as Exhibit 5.1 to the
Registration Statement.

     We are familiar with the Registration  Statement,  and we have examined the
Corporation's  Articles of Incorporation,  as amended to date, the Corporation's
Bylaws,  as amended to date, and minutes and  resolutions  of the  Corporation's
Board of Directors and shareholders. We have also examined such other documents,
certificates,  instruments and corporate records,  and such statutes,  decisions
and questions of law as we have deemed  necessary or appropriate for the purpose
of this opinion.

     The opinions herein are limited to the Federal laws of the United States of
America and the corporate law of the State of New Jersey.  We do not express any
opinion  concerning any law of any other  jurisdiction  or the local laws of any
jurisdiction.

     Based upon the  foregoing,  we are of the opinion that the shares of Common
Stock to be sold by the Selling  Stockholders  (as  defined in the  Registration
Statement)  to the public,  when issued and sold in the manner  described in the
Registration  Statement (as  amended),  will be validly  issued,  fully paid and
non-assessable.

     We hereby  consent to the filing of this opinion as an to the  Registration
Statement  and to the use of our  name  in the  Prospectus  constituting  a part
thereof in  connection  with the matters  referred  to under the caption  "Legal
Matters."

Very truly yours,
