E-MAIL: Dee Morrison, dmmorrison@mail.arc.nasa.gov. NASA/ARC plans to issue a Request for Quotation (RFQ) for a refrigerated ultracentrifuge to be used for separation of subcellular components and for preparation and analysis of purified proteins from tissues and bacterial preparations. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/ARC intends to purchase the items from Bechman Instruments, Inc., under the authority of 10 U.S.C. 2304(c), based on capability of centrifugation speeds of up to 600,000 x g and with very accurate speed and temperature controls. Unique features should include: 1. A programmable controller permitting delayed start and run times. 2. A vacuum encased drive mechanism which provides extremely accurate speed changes. 3. An imbalance-tolerant drive which allows for slight differences in tube volumes, permitting rapid sample loading. 4. An accurate peltier thermoelectric cooling mechanism that doesn't require frequent maintenance, drive oil, or chlorofluorocarbons. 5. A power failure recovery mechanism that allows a run to be resumed regardless of rotor speed once power is available. 6. The drive mechanism permits compatibility with rotors currently used at Ames. In addition, this acquisition will require the trade-in of a used Beckman L5-65 Ultracentrifuge. The Government intends to acquire a commercial item using FAR Part 12. Interested firms have 8 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 8 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Oral communications arenot acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
