Abstract:
A reagent reservoir for containing a liquid reagent, the reservoir comprising:a plurality of reservoir side walls and a patterned bottom wall collectively defining a reservoir interior for containing the liquid reagent; and a plurality of recesses in the patterned bottom wall collectively surrounded by the reservoir side walls, the volume of the reservoir interior being substantially greater than the collective volume of the recesses, each recess facing upwardly, and each recess including a top edge, bottom, and a plurality of side wall portions, said side wall portions collectively surrounding said bottom wherein the side wall portions include four connected substantially triangular surfaces angling outwardly from the bottom to the top edge thereby promoting flow of the liquid reagent to the respective recess bottoms to allow full extraction of the liquid reagent, wherein the height of the reservoir side walls is at least several times the depth of the recesses in the patterned bottom wall so that liquid reagent can fill the reservoir to a level above the top edges of the recesses.
