Exhibit 31.1

                                  CERTIFICATION

      I, John G. Baust, Chief Executive Officer and Chief Financial Officer of
BioLife Solutions, Inc. (the "Registrant"), certify that:

      (1) I have reviewed this quarterly report on Form 10-QSB of the
Registrant;

      2. Based on my knowledge, this 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 report;

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

      4. I am responsible for establishing and maintaining disclosure controls
and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and
internal control over financial reporting (as defined in Exchange Act Rules
13a-15(f) and 15d-15(f)) for the registrant and I have:


      a) designed such disclosure controls and procedures, or caused such
disclosure controls and procedures to be designed under our supervision, to
ensure that material information relating to the registrant, including its
consolidated subsidiaries, is made known to me by others within those entities,
particularly during the period in which this report is being prepared;

      b) designed such internal control over financial reporting, or caused such
internal control over financial reporting to be designed under our supervision,
to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles;

      c) evaluated the effectiveness of the registrant's disclosure controls and
procedures, as of the end of the period covered by this report based on such
evaluation; and

      d) disclosed in this report any change in the registrant's internal
control over financial reporting that occurred during the registrant's most
recent fiscal quarter(the registrant's fourth fiscal quarter in the case of an
annual report) that has materially affected, or is reasonably likely to
materially affect, the registrant's internal control over financial reporting;
and

      5. I have disclosed, based on my most recent evaluation of internal
control over financial reporting, to the registrant's auditors and the audit
committee of registrant's board of directors (or persons performing the
equivalent functions):


      a) all significant deficiencies and material weaknesses in the design or
operation of internal control over financial reporting which are reasonably
likely to adversely affect the registrant's ability to record, process,
summarize and report financial information; and

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