66 -- PHYSICA UDS 200 FLUIDS RHEOMETER SYSTEM SOL 53SBNB860098 DUE 072998 POC Cavlin Montgomery (301) 975-6334 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 an fluid rheometer, with concentric cylinder geometry, which can provide controlled stress, controlled strain, and dynamic (oscillatory) measurements of the rheological behavior of fluids with viscosities ranging from 10 mPa-s to over 100 mPa-s. The rheometer is intended for simultaneous small-angle neutron scattering (SANS) measurements and, therefore, must be adaptable for operation on the SANS instruments at NIST's Center for Neutron Research. This requirement places certain dimensional constraints on the equipment and implies that the rheometer's concentric cylinder geometry accommodate the passage of a neutron beam through the test fluid, and that the starting/stopping of rheological measurement can be controlled by the SANS instruments' data acquisition computer system. This Acquisition is a Small Business Set-Aside. Required delivery is 2 months from contract award. F.O.B. Destination, Gaithersburg, Maryland. Delivery location is the National Institute of Standards and Technology, Building 301, Receiving Room, Gaithersburg, MD 20899.
