66 -- CALORIMETRY SYSTEM SOL 53SBNB860006 DUE 121297 POC Trena N. Bercaw, (301) 975-6324; FAX (301) 963-7732 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) has a requirement for a calorimetry system to be used for measurement of enthalpies of dilution and mixing of aqueous electrolytes as well as for the measurement of reactivity and stability of ion-exchanger materials in water and electrolytes. The system shall consist of an isothermal microcalorimeter, a flow cell assembly kit, a cooling bath and data modeling software. The microcalorimeter shall be capable of measuring changes in heat flow as small as 25 nanocalories/second, and heat effects as small as 10 micro-calories, with a standard operating temperature from 0 to 100 degrees C. The flow cell assembly kit shall include a Hastelloy-C flow mixing cell, a Hastelloy-C flow adsorption cell and accessory electronic controller, a two-channel peristaltic pump, cell stirrers and glass adsorption bed cartridges. In addition, cell assembly kit shall be designed to have no vapor space and shall have flow mixing cells that can be easily replaced and can be fabricated from other alloys. The cooling bath shall have a temperature range of -35 to 200 degrees C; stability of +/-0.01 degrees C; and cooling capacity of 100 Watts at -30 degrees C to 750 Watts at + 30 degrees C. The F.O.B. Point shall be destination, Gaithersburg, Maryland. Delivery is required within 30-90 days after award. It is the intent of the government to negotiate only with Calorimetry Sciences Corporation of Provi, Utah, in accordance with FAR 13.106-2 (a)(5), as the only source reasonably available to satisfy the needs of the government. Calorimetry Sciences Corporation is the only known source able to provide the type of calorimetry system required by the government. It is the government=s intent to issue a firm fixed price purchase order for this requirement. This notice of intent is not a request for competitive quotations, however all quotes received by the response date of 12/22/97, will be considered by the government. A determination by the Government not to compete this requirement based upon response to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. No solicitation package is available. (0345)
