Abstract
Abstract The present invention is a device which allows for receiving, distributing and storing a sample into numerous aliquots of small volume without air entrapment and with retention of aliquots when the device is manipulated. The device allows for the treatment of any or all of the aliquots with the same or different reagents and/or other chemical additives. The device comprises a housing for containing a body for guiding a sample into a plurality of wells without the need for pipetting aids, without multiple manipulations, without the retention of air and for retaining sample in the wells.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
47 words
A device for dividing a sample into aliquots without air entrapment and for retention of aliquots therein, comprising: a housing; and a body associated with said housing for guiding a sample into a plurality of wells without air entrapment and for retaining said sample in said wells.
Claim 2
Dependent Claim
15 words
The device of Claim 1 further comprising a closure for supplying reagents to each well.
Claim 3
Independent Claim
150 words
A device for dividing a sample into aliquots without air entrapment, comprising: an outer-base element comprising a bottom, an inner planar surface, sidewalls depending from said bottom and substantially perpendicular to said inner planar surface, and individual well bottoms raised from said inner planar surface; and a sample distribution element associated with said outer-base element comprising an upper surface, a lower surface, a trough on said upper surface comprising an unidirectional pathway, a reservoir adjacent to said trough, and each well comprising a sidewall, a sidewall bottom surface, an upper mouth opening and a bottom mouth opening wherein each well is disposed between said upper and lower surfaces and transversely disposed with respect to said trough to form a substantially sharp junction, wherein said sidewall bottom surface and well bottom of each well are substantially parallel to each other and form a spaced means to allow the escape of air.
Claim 4
Dependent Claim
54 words
The device of Claim 3 further comprising: a plurality of posts projecting from said inner planar surface of said outer-base element; and a plurality of corresponding bosses depending from said lower surface of said sample distribution element, wherein said posts and corresponding bosses engage to connect said outer-base element and said sample distribution element.
Claim 5
Dependent Claim
27 words
The device of Claim 3 wherein said sample distribution element is substantially rectangular in shape and said wells are in an ordered array of substantially parallel rows.
Claim 6
Dependent Claim
53 words
The device of Claim 3 further comprising a removable lid comprising an upper surface, a lower surface, sidewalls adjacent to said upper surface and coplanar to said lower surface, a plurality of projections depending from said lower surface and a depending edge adjacent to said upper surface and substantially perpendicular to said sidewalls.
Claim 7
Dependent Claim
22 words
The device of Claim 6 wherein said projections fit within said upper mouth opening of said wells in said sample distribution element.
Claim 8
Dependent Claim
18 words
The device of Claim 6 further comprising an extension raised from said upper surface for viewing said projections.
Claim 9
Dependent Claim
30 words
The device of Claim 6 further comprising: an opening on said lid upper surface; and a conduit on said lid lower surface connected to said opening and to said projection.
Claim 10
Independent Claim
70 words
A method for identifying microbes comprising: (a) distributing liquid sample without air entrapment into a multiple aliquot device comprising an outer-base element, a sample distribution element associated with said outer-base element and a lid removably covering said outer-base element and said sample distribution element; (b) subjecting said sample to at least one substrate useful for identifying and detecting microbes; and (c) examining said sample for chemical or optically detectable change.
