Claims
- 1. A device for providing at least one precise volume of fluid for use in a chemical process requiring deliver of precise volumes of reactant fluids, said device comprising:
- (a) two substantially parallel sides;
- (b) two other sides, symmetrically located opposite each other and connected to said two substantially parallel sides to form a box shape;
- (c) a bottom portion, connected to all four of these sides and having an internal configuration of a vee-shaped trough that has an apex aligned substantially perpendicular to said parallel sides;
- (d) a top portion, having a septum therein and connected to said sides to form a cartridge having a closed volume; and
- (e) a flange connected to said bottom portion, aligned substantially parallel to said two substantially parallel sides and located substantially midway between said substantially parallel sides, orthogonal to the apex of said trough;
- wherein (i) said flanges and (ii) a portion of an exterior surface of said bottom portion, adjacent to the apex of said trough, form a cross-shaped surface that, when placed in contact with a top surface of a horizontal, flat support surface, will support elements (a)-(e) in an orientation in which the top portion is vertically above said bottom portion.
- 2. A device as in claim 1 wherein all of elements (a)-(e) are part of a unitary body.
