CERTIFICATION PURSUANT TO
                             18 U.S.C. SECTION 1350,
                             AS ADOPTED PURSUANT TO
                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

     I, Bernard M.  Ciongoli,  President,  Chief  Executive  Officer,  and Chief
Financial Officer of Tech Laboratories, Inc. certify that:

1.   I  have  reviewed  this  quarterly   report  on  Form  10-QSB for the  Tech
     Laboratories, Inc.;

2.   Based on my knowledge,  this  quarterly  report does not contain any untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements  made, in light of the  circumstances  under which such
     statements  were made, not misleading with respect to the period covered by
     this quarterly report.

3.   Based  on my  knowledge,  the  financial  statements  and  other  financial
     information  included  in this  quarterly  report,  fairly  present  in all
     material respects the financial condition,  results of operation,  and cash
     flows of the  registrant  as of, and for,  the  periods  presented  in this
     quarterly report.

4.   The  registrant's  other  certifying  officers  and I are  responsible  for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-14 and 15d-14) for the registrant and we have:

     (a)  designed  such  disclosure  controls  and  procedures  to ensure  that
          material  information  relating  to  the  registrant,   including  its
          consolidated subsidiaries,  is made known to us by others within those
          entities,  particularly  during  the  period in which  this  quarterly
          report is being prepared;

     (b)  evaluated the  effectiveness of the registrant's  disclosure  controls
          and procedures as of a date within 90 days prior to the filing date of
          this quarterly report (the "Evaluation Date"); and

     (c)  presented  in  this  quarterly   report  our  conclusions   about  the
          effectiveness  of the disclosure  controls and procedures based on our
          evaluation as of the Evaluation Date.

5.   The registrant's other certifying  officers and I have disclosed,  based on
     our most recent  evaluation,  to the  registrant's  auditors  and the audit
     committee of the registrant's board of directors (or persons performing the
     equivalent function):

     (a)  all  significant  deficiencies  in the design or operation of internal
          controls  which could  adversely  affect the  registrant's  ability to
          record,  process,  summarize,  and  report  financial  data  and  have
          identified for the  registrant's  auditors any material  weaknesses in
          internal controls; and

     (b)  any fraud, whether or not material,  that involves management or other
          employees who have a  significant  role in the  registrant's  internal
          controls.

6.   The  registrant's  other  certifying  officers and I have indicated in this
     quarterly report whether or not there were significant  changes in internal
     controls  or in other  factors  that could  significantly  affect  internal
     controls  subsequent to the date of our most recent  evaluation,  including
     any corrective actions with regard to significant deficiencies and material
     weaknesses.
