Pipette guide and method
First Claim
1. A guide for a manual pipette in combination with a well plate for, precise reagent delivery to a particular well plate reservoir, said pipette guide mounted atop said well plate, said well plate comprising:
- a) a number of individual rows and columns of reservoirs for receiving reagents,said pipette guide comprising;
a) a cover, said cover defining a window to expose said reservoir rows and columns;
b) a slide, said slide having a top and a bottom, side slide moveably affixed to said cover, said slide defining a slot, said slot exposing only one row of said reservoirs within said window while covering other of said reservoirs rows within said window;
c) a reservoir isolator, said reservoir isolator mounted to move along said row of reservoirs exposed by said slide slot to a particular reservoir exposed in said row; and
d) a rotatable slide rod, a lug, said lug attached to said slide, said slide rod positioned through said lug proximate said slot, said reservoir isolator mounted on said slide rod,said reservoir isolator having a width greater than the diameter of said particular exposed reservoir, said reservoir isolator defining a port, said port positioned over said particular exposed reservoir, whereby a pipette can deliver a reagent through said port in to the particular exposed reservoir, while said reservoir isolator shields reservoirs adjacent to said particular exposed reservoir in said row of reservoirs exposed by said slot.

Abstract
A guide for use with a manual pipette used in loading well plates is provided which insures the accuracy and efficiency of reservoir loading. The pipette guide is used in combination with a conventional well plate generally having 96-384 reservoirs. The guide allows for more exact delivery of liquid reagents to selected reservoirs without concern for missing or duplicating particular reservoirs during loading. The pipette guide is releasably locked onto the well plate and a slide outlines a specific row of reservoirs. In addition a reservoir isolator allows delivery to a single selected reservoir and protects against cross-contamination. Adjustable rods with notches therealong allow the slide and isolator to be precisely moved and indexed as desired.

10. A manual pipette guide for use with a well plate having a plurality of reservoirs comprising:
- a cover, said cover defining a window, a slideable lock, a rail, said lock positioned on and slideable along said rail, said rail affixed to said cover, a side rod, said side rod attached to said cover along one side, a slide, a flange, said flange affixed to said slide, said side rod engaging said flange, said slide defining an arcuate edge, said arcuate edge engaging said cover along the side opposite said side rod, a slide rod, said slide rod mounted on said slide, said slide rod normal to said side rod, a reservoir isolator, said reservoir isolator movably positioned on said slide rod, said reservoir isolator defining a port, said port allowing a guide for a pipette to deliver a reagent to a specific well plate reservoir, said lock for attaching said cover to the well plate.
