Reagent probe and method for fabrication thereof

摘要

A probe for aspirating and dispensing fluids is provided with a concave arcuate termination of the tubular bodywall forming a terminal orifice, in which the tip of the arcuate termination projects inwardly toward the tubular axis; the projection of the tip extends to a position at a distance in the range of approximately 1/4 to about 3/4 of the distance perpendicularly across the outside diameter of the bodywall.
