A multi-well microfiltration apparatus and method are provided and feature
a manual touch-off system for transferring pendent drops hanging from
discharge-conduits of a discharge-conduit array to respective receiving
wells or receiving holes of a corresponding receiving array, with minimum
or no cross-contamination between the discharge conduits, or the
receiving wells or receiving holes. The manual touch-off is achieved by
manually shifting a carriage that supports one of the arrays, into a
position whereat pendent drops of fluid hanging from the distal ends of
the discharge conduits contact the inner sidewalls of the corresponding
receiving wells or receiving holes of the receiving array.
