Robots in the clinical laboratory

The recent availability of robots specifically designed for use in laboratories raises the question 'Is there a place for robots in clinical chemistry laboratories?' Some direct experience with the Zymark robot over the last 18 months suggests that the answer to this question is equivocal and it is my intention to elaborate on this lheme. Over the last 15 to 20 years there has been a steady inc...

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

Semiautomatic Determination of Serum Glucose and Urea Using a New Three-channel Pipetting Machine.

T’ HE ECONOMICAL MANAGEMENT of a hospital laboratory requires the gradual replacement of manual by mechanical manipulations. Fully automatic devices are now available for serial determinations on blood arid other biologic fluids, but their use is sometimes limited by financial and space considerations, even to the big laboratories performing some hundred or more analyses of the same type every ...
