To the Trustees of the Millipore Corporation
Employees' Participation and Savings Plan:

We  have  audited  the  accompanying  statements  of  net  assets
available   for  plan  benefits  of  the  Millipore   Corporation
Employees' Participation and Savings Plan as of December 31, 1997
and  1996,  and  the related statement of changes in  net  assets
available for plan benefits for the year ended December 31, 1997.
These  financial statements are the responsibility of the  Plan's
management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

We  conducted  our  audits in accordance with generally  accepted
auditing  standards.  Those standards require that  we  plan  and
perform  the  audit to obtain reasonable assurance about  whether
the  financial statements are free of material misstatement.   An
audit  includes  examining, on a test basis, evidence  supporting
the  amounts  and  disclosures in the financial  statements.   An
audit also includes assessing the accounting principles used  and
significant  estimates made by management, as well as  evaluating
the  overall  financial statement presentation.  We believe  that
our audits provide a reasonable basis for our opinion.

In  our  opinion,  the  financial statements  referred  to  above
present  fairly,  in  all  material  respects,  the  net   assets
available   for  plan  benefits  of  the  Millipore   Corporation
Employees' Participation and Savings Plan as of December 31, 1997
and  1996  and  the  changes  in net assets  available  for  plan
benefits for the year ended December 31, 1997 in conformity  with
generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the
basic  financial  statements taken as a whole.  The  supplemental
schedules  of  (1)  assets held for investment purposes  and  (2)
reportable   transactions  are  presented  for  the  purpose   of
additional  analysis and are not a required  part  of  the  basic
financial  statements but are supplementary information  required
by  the Department of Labor's Rules and Regulations for Reporting
and  Disclosure under the Employee Retirement Income Security Act
of  1974.   The Fund Information in the statements of net  assets
available for plan benefits and the statement of changes  in  net
assets  available for plan benefits is presented for purposes  of
additional  analysis  rather  than  to  present  the  net  assets
available  for plan benefits and changes in net assets  available
for  plan benefits of each fund.  The supplemental schedules  and
Fund  Information have been subjected to the auditing  procedures
applied  in the audits of the basic financial statements and,  in
our  opinion,  are  fairly  stated in all  material  respects  in
relation to the basic financial statements taken as a whole.

A.   Description of the Plan

     The   Millipore  Corporation  Employees'  Participation  and
     Savings  Plan-"1994 Restatement" as amended, (the  Plan)  is
     subject to the provisions of the Employee Retirement  Income
     Security  Act of 1974 (ERISA).  The Plan includes  a  profit
     participation  feature (Participation  Plan),  which  covers
     U.S.  and Puerto Rico employees who have at least two  years
     of   continuous  service  with  Millipore  Corporation  (the
     Company),  and a savings plan feature (Savings Plan),  which
     covers  only U.S. employees who have one year of  continuous
     service  with  the Company.  The Plan is administered  by  a
     Committee (the Committee), consisting of at least 5 members,
     appointed by the Board of Directors of the Company.

     The  Plan was amended in April 1997 to include employees  of
     the Amicon Separation Science Business of W.R. Grace and Co.
     (Amicon)  which  was acquired by Millipore on  December  30,
     1996  and  employees  of Tylan General, Inc.  (Tylan)  which
     merged  with  Millipore on January 22, 1997.  The  committee
     voted  on April 7, 1997 to transfer the assets of the  Tylan
     General,  Inc. Incentive Savings Plan (the Tylan Plan)  into
     the Plan.  Effective June 1, 1997, benefits ceased to accrue
     under  the  Tylan Plan and the net assets were  subsequently
     transferred  to  the  Plan as of June 30,  1997  (the  "Plan
     Merger date").
     
     All  Amicon and Tylan employees became eligible for purposes
     of  participating in the Participation Plan contribution  on
     the  latest  of the following dates: the date  the  employee
     completes  two  years  of service,  the  date  the  employee
     becomes  an eligible employee or the acquisition  or  merger
     date.  All Amicon and Tylan employees have been given credit
     for  all  continuous service with Amicon or Tylan as  if  it
     were  service  with the Company for purposes of  determining
     eligiblity for benefits and the amounts of any Savings  Plan
     matching contributions.
     
     All  Amicon  employees  became  eligible  employees  in  the
     Savings  Plan on the later of the acquisition  date  or  the
     date  of their employment with the Company, for the purposes
     of  making Savings Plan contributions and receiving  Savings
     Plan  matching  contributions.  All Tylan  employees  became
     eligible for making Savings Plan contributions and receiving
     Savings Plan matching contributions on the Plan Merger date,
     provided  the  Tylan  employee  was  otherwise  an  eligible
     employee as defined by the Plan.

     Under    the   Participation   Plan,   the   Company   makes
     discretionary  contributions to the Plan of a percentage  of
     the  Company's profits as designated by the Company's  Board
     of  Directors.  Contributions are allocated to participants'
     accounts based on participants' compensation during the year
     for  which the contribution is made and are invested in  the
     Balanced  Fund.   The Participation Plan is integrated  with
     the  Retirement Plan for Employees of Millipore  Corporation
     (Retirement   Plan),   a  separate  plan,   which   provides
     guaranteed  retirement  income levels  to  the  extent  such
     income levels are not provided by the Participation Plan.

A.   Description of the Plan (Continued)

     Under  the  Savings  Plan, participants may  make  voluntary
     contributions of up to 15% of their eligible compensation on
     a  pre-tax basis. All participants with 10 or more years  of
     service receive a Company match of 50% of their contribution
     up  to 6% of their eligible compensation.  Participants with
     less than 10 years of service receive a Company match of 25%
     of   their   contribution  up  to  6%  of   their   eligible
     compensation.

     Contributions  under  the Savings  Plan  and  the  Company's
     matching  amount  may  be  invested,  at  the  participants'
     election,  in  any  of  the funds  available  in  the  Plan.
     Participants are permitted to invest in more than  one  fund
     and  are  generally  allowed to borrow  from  the  Plan  the
     amounts  contributed  by  them and  the  Company's  matching
     amount.

     Borrowings  are  evidenced  by interest  bearing  promissory
     notes  and  are reflected in the Loan Fund net of  principal
     repayments.   All  interest payments  are  credited  to  the
     participant's account.  Participants may borrow  from  their
     fund  accounts a minimum of $1,000 up to a maximum equal  to
     the  lessor  of,  (1)  the  amount of  their  total  account
     (excluding the Participation Plan account), (2) the  greater
     of  $10,000  or  one-half of their  total  account;  or  (3)
     $50,000  reduced by the excess (if any) of (a)  the  highest
     outstanding balance of loans from the Plan during the 1-year
     period ending on the day before the date on which such  loan
     was made, over (b) the outstanding balance of loans from the
     Plan  on  the date on which such loan was made.  Loan  terms
     range  from 1 to 4 1/2 years.  Each loan shall bear  interest
     at  a  standard  rate  established by  the  Committee.   The
     current interest rate is 5.5 percent.

     All  contributions (both employee and employer), and  income
     earned  thereon, under both sections of the Plan, are  fully
     and  immediately vested.  Participants who are 59 1/2  years
     or  older  may  at any time withdraw amounts contributed  by
     them as well as income earned thereon.

     In  the  event  of  a  participant's death,  termination  or
     retirement, all amounts contributed to the Plan  by,  or  on
     behalf  of the participant, including income earned thereon,
     will  be  distributed in a lump sum to  the  participant  or
     beneficiary.  Participation Plan contributions in some cases
     and   income  earned  thereon  may  be  transferred  to  the
     Retirement  Plan  for  distribution in accordance  with  its
     provisions.

     A detailed description of the Plan is available upon request
     at the Company's headquarters in Bedford, Massachusetts.

B.   Summary of Significant Accounting Policies

     Basis of Accounting

     The  financial statements of the Plan are prepared under the
     accrual method of accounting.

     B.   Summary of Significant Accounting Policies (Continued)


     Investment Valuation

     Money  market  funds are valued at cost, which  approximates
     fair  market value.  Mutual funds are recorded at their  net
     asset  value,  which approximates fair market value.  Common
     stocks  are valued at the last reported sales price  on  the
     last business day of the year.  Participant loans are valued
     at cost which approximates fair value.

     The  F&G  GAC  Fund  is a fully benefit-responsive  contract
     fund,   which  carries  no  set  limitations.   The  minimum
     credited  interest rate for both December 31, 1997 and  1996
     is  4.5%.   This  rate is reviewed annually to  reflect  the
     anticipated  yields.  The average yield for the years  ended
     December 31, 1997 and 1996 was 4.5%. The Other Fund consists
     of a series of fully benefit-responsive insurance contracts,
     with certain limitations on liquidation for purposes outside
     of  plan provisions.  The minimum credited interest rate and
     the  average yield was 6.55% for the year ended December 31,
     1997,  respectively. All investments in insurance  contracts
     are  valued at their contract value, which approximates fair
     value.  The Invesco Stable Value Fund is a common collective
     trust GIC Fund (or pooled GIC Fund) which has been valued by
     the  Fund's investment advisor, in the absence of a  readily
     ascertainable  market value, based on the  best  information
     available  as of the end of the period.  Such valuation  has
     been approved by the Committee.
     
     Purchases  and sales of securities are recorded on  a  trade
     date   basis.   Realized  gains  and  losses  on  sales   of
     securities are based on average cost.  The Plan presents  in
     the  statement of changes in net assets available  for  plan
     benefits  the net appreciation (depreciation)  in  the  fair
     value  of  its  investments which consists of  the  realized
     gains    or   losses   and   the   unrealized   appreciation
     (depreciation) on those investments.

     Use of Estimates
     
     The  preparation of the financial statements  in  conformity
     with  generally accepted accounting principles requires  the
     Trustees to make significant estimates and assumptions  that
     affect the reported amounts of net assets available for plan
     benefits  at  the date of the financial statements  and  the
     changes in net assets available for plan benefits during the
     reporting  period  and,  when  applicable,  disclosures   of
     contingent  assets  and  liabilities  at  the  date  of  the
     financial  statements.   Actual results  could  differ  from
     those estimates.

B.   Summary of Significant Accounting Policies (Continued)
     
     Risks and Uncertainties
     The  Plan  provides for various investment  options  in  any
     combination  of  stocks,  bonds,  fixed  income  securities,
     mutual  funds,  money  market funds,  and  other  investment
     securities.   Investment securities are exposed  to  various
     risks such as interest rate, market, and credit risks.   Due
     to  the  level  of  risk associated with certain  investment
     securities, and a level of uncertainty related to changes in
     the   value  of  investment  securities,  it  is  at   least
     reasonably possible that changes in risks in the  near  term
     could materially affect participants' account balances,  the
     amounts  reported  in the statement of net assets  available
     for  plan  benefits, and the statement  of  changes  in  net
     assets available for plan benefits.

     Dividend and Interest Income
     Dividend  income  is  recorded  on  the  ex-dividend   date.
     Interest income is recorded as earned on an accrual basis.

     Contributions
     Contributions from the Company under the Participation  Plan
     are accrued and paid annually based upon a determination  by
     the Board of Directors of the Company in accordance with the
     provisions of the Plan.

     Payment of Benefits
     Benefits are recorded when paid.
     
     Reclassifications
     Certain  reclassifications have been made  to  prior  years'
     financial statements to conform with the 1997 presentation.



C.   Investment Programs

     The Plan's assets are invested among ten investment funds, a
     loan  fund  and a temporary fund (Pan American) which  holds
     the  remaining  Tylan General employees'  balances  not  yet
     transferred into the other ten investment funds.  All of the
     investment  funds available to employees have been  approved
     by  the  Trustees  of the Plan.  Employees  are  allowed  to
     invest  in all ten investment funds and may invest  in  more
     than  one  fund.  Upon enrollment in the Plan, a participant
     may  direct  employee  contributions  and  matching  company
     contributions,  as  well as change their investment  options
     monthly.   All  Company contributions to  the  Participation
     Plan  are  invested  in  the  Balanced  Fund.   The  mix  of
     investments  within the Balanced Fund is determined  by  the
     Trustees  of  the  Plan.  Income earned by  each  investment
     fund, including realized and unrealized gains and losses  on
     investments, is allocated to participants' accounts based on
     their  pro  rata  share of contributions and  income  earned
     thereon.  The investment funds available to employees are as
     follows:

F.   General Termination Condition

     While   the   Company  has  not  expressed  any  intent   to
     discontinue its contribution under the participation feature
     of  the  Plan,  it is free to do so at any  time  under  the
     current provisions of the Plan.  In the event of a permanent
     discontinuance   of   Company   contributions   under    the
     participation  feature  of  the  Plan,  dissolution  of  the
     Company,  acquisition  of  the Company  by  an  unaffiliated

     discontinue  the  Plan, the Plan shall be deemed  terminated
     and  each  participant  shall be entitled  to  an  immediate
     distribution of his account.


G.   Tax Status

     The Internal Revenue Service has determined and informed the
     Company  by a letter dated April 28, 1995, that the Plan  is
     qualified  in  accordance with applicable  sections  of  the
     Internal  Revenue  Code (IRC).  The Plan  has  been  amended
     since receiving the determination letter.  However, the Plan
     administrator and the Plan's tax counsel believe the Plan is
     designed and is currently being operated in compliance  with
     the applicable requirements of the IRC.

When  the assets of two or more plans are maintained in one trust
(Master Trust), such as the Balanced Fund, which holds assets for
both the Savings and Participation Plan and Retirement Plan,  the
value of plan assets held in the Master Trust are subtracted from
the current value of all plan assets at the beginning of the plan
year  in  determining the 5% limitation. The following securities
were traded during the year ended December 31, 1997 in series  of
transactions that were in excess of 5% of the Participation  Plan
total assets excluding the assets of the Balanced Fund at January
1, 1997.
