A method for washing laboratory consumables comprises receiving, in a drawer compartment of a washing device, a rack holding a plurality of laboratory consumables, the drawer compartment selectively movable out and in between, respectively, an open and a closed position, the receiving occurring when the drawer compartment is in its open position; moving the drawer compartment to its closed position; moving a manifold dispenser downward from a loading/unloading position to a washing position; the manifold dispenser in a top compartment of the washing device that is positioned above the drawer compartment when the drawer compartment is in its closed position, the manifold dispenser selectively movable up and down between, respectively its loading/unloading position and its washing position; and directing one or more fluid solutions to contact the plurality of laboratory consumables out of a plurality of liquid outputs of the manifold dispenser.

The invention is directed to a microfluidic device. The device includes an input microchannel, a set of m distribution microchannels, a set of m microfluidic modules and a set of m nodes. The m microfluidic modules (m2) are in fluidic communication with the m distribution microchannels, respectively. The one or more nodes of the set of m nodes branch from the input microchannel, and further branch to a respective one of the set of m distribution microchannels. In addition, a subset, but not all, of the nodes are altered. The nodes of the set of m nodes have different liquid pinning strengths. As a result, the extent in which a liquid passes through one or more of the m microfluidic modules varies based on the different liquid pinning strengths, in operation. Additional sets of nodes may be provided to allow liquid to pass through ordered pairs of modules.
