66 -- MULTI-MODE ATOMIC FORCE MICROSCOPE SYSTEM SOL DADA15-96-R-0029 DUE 071096 POC Contract Specialist R. TAYLOR (202) 782-1285 Contracting Officer Al Bariatti (202) 782-1280 (Site Code DADA15) Walter Reed Army Medical Center intends to enter sole source negotiations with Digital Instruments, Santa Barbara, California, for a multimode atomic force microscope system for the Biophysics Division of the Armed Forces Institute of Pathology. This sole source solicitation is in accordance with FAR Part 6. The atomic force microscope (AFM) system will be used for imaging biological molecules and cellular structures in air and in fluids using the Tapping mode and Tapping mode in fluids imaging techniques with motorized automated cantilever approach. Cantilever oscillations must range in frequency from 10KHz to 1MHz with an amplitude of up to 500nm. Tapping mode in fluids should allow for the oscillation of the entire fluid cell. The AFM system should also be capable of contact, non-contact, magnetic-force modulation, electrical-force modulation, lateral-force modulation, force-modulation imaging in fluids, force-volume imaging, phase-contrast imaging, and fluid cell operation without changing or requiring additional scanners. Justification for other than full and open competition is based on 10 U.S.C. 2304(c)(1), whereby supplies or services required are available from only one source and no other type of supplies or services will satisfy agency requirements. Interested firms may submit a written request to the address listed above, stating name, address and solicitation number. Requests may be faxed to (202) 782-7547. No telephone requests for the solicitation package will be accepted.(0124)
