The testing apparatus is for measurement of ions in body fluids. The apparatus has a plurality of sample cups for containing fluids to be tested, a movable door for controlling access to the sample cups, and a plurality of measuring electrodes for immersion into the fluid to be tested. There is a hand operated device for moving the electrodes and the cups with respect to each other to alternately put the electrodes in a first position permitting access to the cups and in a second position in which the electrodes are immersed in the fluids to be tested contained in the cups. Means for mounting the cups in the testing apparatus are engaged with means for oscillating the cups independently of the electrodes. The oscillation fully exposes the electrodes to a representative sampling of the fluids within the cups and thus enhances the accuracy of the test being performed. The method is for the measurement of chlorides, ionized calcium, sodium and potassium as well as other ions in fluids obtained from the body or elsewhere. The method includes the step of using the controlled oscillation of a small sample fluid in direct contact with an electrode, to thoroughly expose a true representative sample to the electrode for measurement.

A wafer packaging system for clean packaging and damage-free transporting of semiconductor wafers. The system includes tubular outer and inner containers, the inner container adapted to be contained by the outer container with the longitudinal axes of both containers extending in the same axial direction. The inner container includes provision for holding a plurality of the semiconductor wafers in spaced face-to-face relationship. The system provides a sealed container arrangement preventing contaminants outside the outer container from contaminating wafers within the inner container. Shock-absorbing features associated with the containers prevent shocks applied to the outer container from damaging the wafers.
