NIST researchers have addressed crucial calibration procedures for an advanced rheological technique that can make measurements on the structural dynamics of
Researchers at the National Institute of Standards and Technology (NIST) have developed an optical system that accurately measures the flow of extraordinarily
Today, demonstration vehicles are refueled with hydrogen from dispensers within 3 to 5 minutes using sequential gas releases from a bank of pressurized
Our goal is to develop combinatorial and high-throughput measurement approaches for rapid characterization of the structure and phase behavior of multicomponent
This NIST-wide collaborative project aims to improve biotechnology and medical diagnostics by increasing the resolution and precision of measurements of cells

Flow cytometers are indispensable for clinical studies, yet are hindered by inherent uncertainties. We have developed an optofluidic device capable of multiple
The dynamic gravimetric standard is used to calibrate micro-flow meters and to conduct research on new flow sensors. This micro-flow standard measures mass
A compressor is used to pressurize up to twenty-five 40 L gas cylinders to 35 MPa. The cylinders can then be used as a source of rapidly changing gas flow by
NIST uses pressure, volume, temperature, and time (PVTt) standards to calibrate gas flow meters. PVTt flow standards generate selected, steady gas flows through
NIST’s wind tunnel can produce air speeds between 0.15 m/s and 40 m/s. The air speed reference is a Laser Doppler Anemometer (LDA) with an uncertainty of 2.5 %
