Device for storage and dispensing of reagents

A method for dispensing one or more reagents, the method comprising:

• actuating a valve of a storage chamber to select a first fluid for dispensing, the first fluid being stored in a first storage well enclosed in the storage chamber, wherein selecting the first fluid for dispensing aligns a valve channel of the valve with a first transfer channel of the first storage well with an outlet manifold of the storage chamber to allow fluid communication therebetween;
• pressurizing an internal volume of the storage chamber to pressurize a first storage volume of the first storage well and cause the first fluid to egress from the first storage well and through the first transfer channel, valve channel, and outlet manifold;
• and
• actuating the valve to select a second fluid for dispensing, the second fluid being stored in a second storage well enclosed in the storage chamber, wherein selecting the second fluid for dispensing positions the valve channel out of alignment with the first transfer channel and the outlet manifold such that the first fluid is prevented from being dispensed from the first storage well.
