66 -- BIOCORE SYSTEM SOL 263-95-Q-(GR)-1659 DUE 093095 POC Patricia Pemberton (301)594-0862 Purchasing Agent, Leroy jennings Contracting Officer 496-6411. The NIH intends to procure on a sole source basis under the authority of far 13.106 (A) the following equipment: A biocore system. The equipment shall be a microcomputer based system capable of real time analysis of biospecific interactions. The system shall use continuous flow technology to process samples. The system shall use optical detection of surface plasmon resonance for sample processing. The system shall consist of a processing unit, including liquid handling and optical subsystems, a system controller operating with BIAlogue personal computer (PC) software, a biosensor chip, Pharmacia #CM5 or equivalent, and a starter set of appropriate reagents for system start-up and use. The processing unit shall include two (2) each liquid delivery pumps capable of flow rates in the range of 1-5000ul/min. with incremental steps of 1ul/min. The processing unit shall provide for the flow rate accuracy of (+/-2% in the 1-100ul/min. range for liquids at 25'C. The processing unit shall include an autosampler with precision of: (a) (4% CV @ 50ul (b) (2% CV @ 5ul. The processing unit shall include an integrated u-Fluidic Cartridge with loops of (a) 2x5ul and (b) 2x45ul. The optical subsystem shall include a detection unit LED (Light Emitting Diode) operating a wavelenght of 760nm with a bandwidth of (5nm. The system controller shall provide for operating BIAlogue software under Microsoft Windows version 3.0 or better. The system shall use 120VAC as the primary power source, with a lithium battery backup for memory protection. Used equipment is acceptable to the Government to fulfill program needs for this requirement. It is the Government's belief that these requirements will only be met by PN Leasing. This is not a formal solicitation. However, concerns that respond to this notice must be furnish concise responses directed specifically to the requirements mentioned above. Respondents will not be notified of the evaluation results. (0256)
