Claim 16:
17. A molecular filtration device comprising:
an upper portion; and
a lower portion;
wherein said upper portion comprises two upper ports;
wherein said two upper ports comprise a first upper port and a second upper port;
wherein said first upper port is configured to receive a first upper flow device;
wherein said second upper port is configured to receive a second upper flow device;
wherein said first upper flow device is configured to alternate between injecting and not injecting solution;
wherein said second upper flow device is configured to alternate between injecting and withdrawing solution;
wherein said lower portion comprises one or more lower ports and a reservoir;
wherein said one or more lower ports are configured to receive one or more lower flow devices;
wherein said lower flow devices are configured to alternate between injecting and withdrawing solution from said reservoir;
wherein said upper portion comprises a channel forming lip;
wherein a channel forming cavity is formed by said channel forming lip when said upper portion and said lower portion engage one another;
wherein a lower sealing surface of said upper portion and an upper sealing surface of said lower portion are configured to receive and compress a membrane;
wherein a channel is defined by said channel forming cavity and said membrane;
wherein said membrane is a molecular weight cut off filtration membrane;
wherein said upper sealing surface of said lower portion and said lower sealing surface of said upper portion are configured to apply a pressure to one another through said membrane;
wherein said upper sealing surface of said lower portion is raised relative a top surface of said lower portion;
wherein said upper ports and said one or more lower ports are oriented horizontally from said upper portions and lower portions, respectively;
wherein said one or more lower ports comprise a first lower port and a second lower port;
wherein said lower portion and upper portion comprise one or more alignment pins and one or more alignment holes;
wherein said one or more alignment holes are configured to receive said one or more alignment pins;
wherein said one or more alignment pins are located on said lower portion and said one or more alignment holes are location on said upper portion; and
wherein said one or more alignment holes and said one or more alignment pins are located on a single side of said lower and upper portions.
