Abstract
Apparatus and methods for analyzing fluid such as blood serum. A probe used for transferring some of the fluid to a testing station causes a change in circuit capacitance when the probe contacts the fluid. This change in capacitance causes production of a control signal which effects cessation of the descent of the probe into the fluid.
