ABSTRACT:
A probe-gripper for automated sample preparation systems is disclosed, including a sample tube (12), an annular electrode (18), a barrel (40) surrounding the electrode, the barrel and the electrode being connected to a capacitance measurer, an annular elastomeric member (30) surrounding at least a portion of the electrode, the opposite end portions of the elastomeric member being secured to the electrode with an intermediate portion of the elastomeric member being free from the electrode to create an inflatable bladder, and passageways extending lengthwise of the probe to conduct pressurized fluid to the bladder to expand and contract it between gripping and release positions.
