Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
246 words
A device for washing and storage of electrophoresis components, comprising a rectangular sheet of material having two parallel first sides and two second sides perpendicular to said first sides, said rectangular sheet having the following cutout portions: (a) end notches along each first side, with the end notches on one first side being aligned with the end notches on the other first side; (b) a central opening having two opposite sides; (c) side notches cut at each opposite side of the central opening, said side notches on each side being aligned with the side notches on the other side, and with the end notches on the first sides; (d) corner cutout areas adjacent said end notches, wherein said sheet is bent to form a central segment around said central opening which is contiguous with two side segments, each of said side segments being contiguous with a foot segment containing end notches, wherein said device may be placed on a surface with said central segment parallel to said surface, said side segments at about a 90° angle to said central segment, said foot segments at an angle to said surface and each of said side notches positioned directly above an end notch, wherein a space is formed between said foot segments, said surface and the lower edge of a glass slide placed in a pair of opposite side notches and in end notches below said pair, which space is of sufficient size to accommodate a magnetic stirrer.
