An Evaluation of the “CentrifiChem” Parallel Fast Analyser

The operating principles of the CentrifiChem are briefly described and the results of the evaluation are summarised. The pipettor, the temperature control unit, and the photometer were tested separately, but the remainder of the instrument is interdependent.Up to 10 different tests were used to measure within-batch and between-day precision, and accuracy. Carryover was found to be small, and for the six tests investigated the linearity was good. Estimates are given of the running costs, and also included are sections on the reliability and safety of the instrument.Since it requires only a small volume of serum, it is ideally suited to paediatric requirements. When used as an enzyme analyser it can work at about 200 specimens per hour.
