The USDA, Agricultural Research Service intends to issue and award to the Anton Paar USA, Ashland, VA on a sole source basis. Award will be made pursuant to 41 U.S.C.253(c)(1)--Only one responsible source and no other supplies or services will satisfy agency requirements. The U.S. Department of Agriculture proposes to sole source purchase the SurPASS Electrokinetic Analyzer. Description of Supplies/Services: The SurPASS Electrokinetic Analyzer measures surface charge directly on cotton fabrics of a wide variety. It is equipped with an auto-titration capability which enables the user to study changes in the zeta potential with respect to changes in pH. The enormous flexibility of the SurPASS measuring cells enables the zeta potential analysis of solids of almost any size and shape. The range of applications starts with powder samples of particle size from some tenth of microns to more than one millimeter. The same measuring cell accomodates fibre material of different origin like glass, carbon or textile fibres. The step towards samples with planar surfaces only requires the exchange of the measuring cell. This technological feature involving direct measurement of zeta potential on whole textiles fibers is not available in any other instrument sold in the U.S. Shall be delivery FOB to the USDA, ARS, SRRC, New Orleans, Louisiana. Responses are to be received within 5 days of this notice. The NAICS Code/Size is 333292. This procurement will be processed pursuant to FAR part 12, Acquisition of Commercial Items.
