Guidelines (1988) for listing specifications of centrifuges

Instrument selection and evaluation

Recent years have seen rapid increases in the variety, cost and complexity of instruments used in analytical chemistry. Gone are the days when choice was a simple task and any mistake did not lead to a major financial embarassment which had to be lived with for perhaps a decade. Not only is the capital investment required in the laboratory increasing, but, in the present world economic climate,...

Gas Centrifuge Theory and Development: A Review of U.S. Programs

This article gives a historical and technical review of the U.S. gas centrifuge efforts between 1934 and 1985. The first section tells of how the United States initially led in centrifuge design, only to abandon the still-immature technology in the midst of the Manhattan Project. While interest in the technology continued in Europe, the United States decided that centrifuges were not a viable a...

Beam & Shell Models for Composite Straight or Curved Bridge Decks with Intermediate Diaphragms & Assessment of Design Specifications

In this research effort, the generalized warping and distortional problem of straight or horizontally curved composite beams of arbitrary cross section, loading and boundary conditions is presented. An inclined plane of curvature is considered. Additionally, the stiffness of diaphragmatic plates has been introduced in the formulation in order to compare with the case where rigid diaphragms are ...

Observations on centrifugation: application to centrifuge development.

This report outlines the background to the development of an automated, serial, discrete centrifuge, reporting on the criteria considered essential in such an instrument. We established the criteria by examining the detailed logistics of centrifuge operation in a hospital laboratory. The mean sample load per run, using six centrifuges, was 13.6 samples, and the user-selectable cycle time ranged...

IFCC Guidelines (1990) for selection of safe laboratory centrifuges and for their safe use with general purpose appendices concerning centrifuge nomenclature, quantities and units, and calculation of centrifugal acceleration
