66 -- ELECTRON SPIN RESONANCE SPECTROMETER WITH PC INTERFACE AND TEMPERATURE CONTROLLER SOL 273-97-P-0007 DUE 070997 POC Contact Mary W. Hogan, Contracting Officer (919) 541-3813 This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. The solicitation is being issued as a Request for Proposal (RFP) #273-97-P-0007. The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 90-46. The Standard Industrial Classification Code is 3826 and the small business size standard is 500. NIEHS is interested in procuring one Electron Spin Resonance Spectrometer with PC Interface and Temperature Controller. Nine mandatory specifications are: (1) all types will be considered because of the variety of electron spin resonance spectrometers commercially available; (2) sensitivity of at least 0.8x1019 spins/Gauss; (3) automatic tuning of bridge and cavity each time a new sample is measured; (4) PC-based data acquisition software; (5) automatic calibration of the modulation amplitude and phase for optimum sensitivity; (6) ESR spectral simulation software for both solution and powder spectra; (7) quartz finger dewar (77 degrees K) and temperature controller with a temperature range from 100 degrees K to 373 degrees K for largest possible sample volume flat cell; (8) six-inch magnet with highest possible field homogeneity and spectral resolution and heat exchanger; and (9) TM110 cylindrical cavity designed to accommodate 17-mm wide flat cells for aqueous solution studies. Within 120 days after award of the Contract, delivery shall be made FOB Destination to the NIEHS South Campus laboratory located at room F028 at 111 Alexander Drive, Research Triangle Park, North Carolina. The provision at FAR 52.212-1, Instructions to Offerors -- Commercial, applies to this acquisition; there are no addenda to the provision. FAR 52.212-2, Evaluation -- Commercial Items applies and the evaluationcriteria included in paragraph (a) are herein listed. The ESR capabilities of the instrument using X-band microwaves to detect and provide structural information for free radicals and radical adducts will be determined on the following mandatory criteria: (a) sensitivity of the X-band ESR spectrometer will be measured using a standard weak pitch sample and a standard rectangular TE102 type cavity; a signal/noise ratio of 300:1 correspondence to a sensitivity of 0.8x1010 spins/Gauss (30 points); (b) a TM110 or similar cavity holding 200 microliter or more of biological sample in the active region will be used to provide the largest possible sample thereby giving the maximum molar sensitivity (30 points); (c ) a six-inch magnet with high field homogeneity and at least a 60 mm gap with heat exchanger is required (10 points); (d) automatic tuning of the bridge and cavity each time a new sample is used will be required (10 points); (e) a PC-based acquisition software in conjunction with simulation software for solution and powder spectra will be provided (10 points); and (f) a temperature controller for flat cells in the TM110 cavity will be provided (10 points). The technical proposal is paramount and price will be a determining factor only if proposals are technically equivalent. Overall award shall be made on the basis of a best buy analysis. Offerors shall include a completed copy of the provision at FAR 52.212-3, Offeror Representations and Certifications -- Commercial Items, with its offer. FAR clause at 52.212-4, Contract Terms and Conditions -- Commercial Items, applies to this acquisition; there are no addenda to this clause. FAR clause at 52.212-5, Contract Terms and Conditions Required To Implement Statutes Or Executive Orders -- Commercial Items, applies to this acquisition and additional FAR clauses cited in this clause which are applicable are: 52.203-6, Restriction on Subcontractor Sales to the Government, with Alternate I; 52.203-10, Price or Fee Adjustment for Illegal or Improper Activity; 52.219-8, Utilization of Small Business Concerns and Small Disadvantaged Business Concerns; 52.219-9, Small, Small Disadvantaged and Women-Owned Small Business Subcontracting Plan; 52.219-16, Liquidated Damages -- Subcontracting Plan; 52.222-26, Equal Opportunity; 52.222-35, Affirmative Action for Special Disabled and Vietnam Era Veterans; 52.222-36, Affirmative Action for Handicapped Workers; 52.222-37, Employment Reports on Special Disabled Veterans and Veterans of the Vietnam Era; 52.225-3, Buy American Act -- Supplies; and 52.225-18, European Union Sanction for End Products. The successful offeror shall provide, at no additional cost to the Government, installation and training to selected Government employees. There are no applicable CBD numbered notes. Offers are due not later than 4:30 p.m. Eastern Standard Time on July 9, 1997, at the Acquisitions Management Branch at Suite 100 at the National Institute of Environmental Health Sciences East Campus at 4401 Research Commons Building, 79 Alexander Drive, Research Triangle Park, NC 27709. For information concerning this solicitation, contact Mary W. Hogan at 919-541-3813. All responsible sources may submit a proposal, which shall be considered by the agency. (0167)
