Abstract

A pipette guide for a standard well plate provides improvements over conventional guides. The improvements include: reference characters to signify a columns of wells exposed, an aperture for viewing those characters, a angled slot and open ended isolator for improved ergonomic function and visibility, a multilevel slide to help prevent contamination and a bi-directional selection assembly for selecting a 96 or 384 well plate.

Claims

1. A guide device for a well plate comprising:

(a) a slide comprising an insertion slot for a tip of a liquid dispensing device;

said slot comprising opposing rimmed edges at the perimeter of its opening provided on the bottom surface of said slide;

said opposing rimmed edges comprising a pair of acutely angled and obtusely angled side walls, wherein said side walls defining a slope with respect to the plane of said slide;

said acutely angled side wall being truncated to provide a perpendicular rimmed edge to increase visualization and liquid dispensing accuracy;

(b) a flange, said flange attached to said slide, said flange defining an aperture;

(c) a side rod, said side rod comprising reference characters, said reference characters positioned on said side rod, said flange slidably engaging said side rod, said reference characters viewable through said aperture; and

(d) a well plate cover, said well plate cover engaging said side rod.

2. The guide device of claim 1, further comprising:

a side rod shoulder, said side rod shoulder comprising a side rod ridge, said side rod ridge positioned on said side rod shoulder, said side rod shoulder attached to said side rod; and

a side rod lug, said side rod lug attached to said well plate cover, said side rod lug defining a side rod lug recess, said side rod lug recess engaging said side rod ridge.

3. The guide device of claim 1, further comprising:

a lateral slide rod, said lateral slide rod affixed to said slide; and

an isolator, said isolator positioned on said lateral slide rod, said isolator defining an open sided port.
