Abstract:

A device is disclosed that comprises a base having first and second reservoirs, each having an inlet and an outlet, and a channel layer comprising an inlet channel in fluid communication with the inlets of the reservoirs, one or more outlet channels in fluid communication with the outlets of the reservoirs, and a channel network comprising at least one channel extending therebetween. In a forward tilted position, a first fluid circuit is formed from the outlet of the first reservoir, through the one or more outlet channels, through the channel network, through the inlet channel, to the both the inlet and outlet of the second reservoir. In a reverse tilted position a second fluid circuit is formed from the outlet of the second reservoir, through the one or more outlet channels, through the channel network, through the inlet channel, to both the inlet and outlet of the first reservoir. Methods of using the device are also disclosed.
