E-MAIL: Lydia H. Butler, lydia. butler@msfc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP)Test Pilot Program for Certain Commercial Items. 1-Quantity One (1) ea -- Self-contained detector system for use in biomacromolecular X-Ray Crystallography consisting of: Rotating anode X-Ray generator, mirrors based on graduated D-spacings, four circle gonimeter, CCD detector, cryocooling system, video camera microscope for viewing specimen crystals, and data collection system. Crystal to detect distance to be under motor control. The system must collect data from a crystal of tetragonal hen egg white lysozyme at 100 K to at least 1.7 A resolution with an overall Rsymm less than 5.0%, a Rsymm in the 1.7-1.8 A range less than 20%, an average redundancy of at least 3.0, a completeness of at least 98% and with fewer than 0.1% of the reflections rejected as outliers. A anomalous difference Fourier map must show the positions of the sulfur atoms. The crystal must be no larger than 0.5 mm in any dimension. The data collected from both large scan (greater than one degree) and fine scan (less than 0.2 degrees) must meet these criteria. Software to be included: Gonimeter and generator control, configurable anticollision software, data collection strategy program, HKL2000 data reduction & evaluation software including fully automatic reflection search and indexing on single or multiple images, support for both fine and wide slicing, control for aligned scans about crystal axes, graphical presentation of HKL-reflection layers, interactive use of video pictures of crystal, orientation matrix and bravais lattice determination, data reduction and evaluation (DENZO-SMN based) reports in HTML and CIF. The provisions and clauses in the RFQ are those in effect through FAC 97-10. All qualified responsible business sources may submit a quotation which shall be considered by the agency. Delivery to MSFC is required within 30 days ARO. Delivery shall be FOB Destination. The DPAS rating for this procurement is DO-C9 . Quotations for the items(s) described above can be submitted via the World Wide Web using the NASA Acquisition Service (NAIS) Request for Quotation System (RFQS) -- See the posted On-line RFQ. quotations can be electronically executed and submitted by an authorized company representative by March 19, 1999. Quoters shall provide the information requested in the On-line RFQ. Although the Government would appreciate all quoters submitting their quotes via the World Wide Web using RFQS, fax or paper quotes will be accepted. If the end product(s) quoted is other than domestic end product(s) as defined in the clause entitled "Buy American Act -- Supplies," the quoter shall so state and shall list the country of origin. Questions regarding this acquisition must be submitted in writing no later than March 15, 1999. Quotations are due by March 19, 1999 to the address specified above. Selection and award will be made to the lowest priced, technically acceptable quoter. Technical acceptability will be determined by information submitted by the quoter providing a description in sufficient detail to show that the product quoted meets the Government's requirement. An ombudsman has been appointed -- See Internet Note "B". It is the quoter's responsibility to monitor this site for the release of amendments (if any). Potential quoters will be responsible for downloading their own copy of this combination synopsis/solicitation and amendments (if any).
