Patent ID: 7713487

Claim:
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.
