66 -- CALVET CALORIMETER BY SETARAM POC Tina Wright, 601-634-4317 The USAE Waterways Experiment Station (WES) proposes to award a contract to Astra Scientific International, Pleasonton, CA, Under authority of 10 U.S.C. 2304(c)(1) for the purchase of a BT.215 DSC Calvet Calorimeter system by SETARAM. The calorimeter will be used to measure thermal properties of geochemical systems at subzero temperatures. The equipment proposed by Astra meets the following criteria: (1) ability to measure accurately and precisely isobaric heat capacities of liquids and solids; (2) ability to control-cool from 200 C to -100 C; (3) ability to control-heat from -100 C to 200 C; (4) ability to hold sample volumes larger than 1 ml; (5) ability to measure the heats of mixing of samples larger than 1ml; (6) ability to make isobaric heat capacity measurements at a range of sample pressures from 10 MPa to 1 kPa; (7) demonstrated reliability and stability in performance. Astra Scientific has the only known calorimeter that will meet the requirements. If no other sources are found, the Government intends to award a contract to Astra Scientific International under the authority of 10 U.S.C. 2304(c)(1). Solicitation documents are not available. Any inquiries should be within 15 days from date of publication of this notice. See numbered Note 22. (0032)
