Abstract: An integrated system for sampling and processing a liquid suspension, the system comprising: a cartridge member comprising a sampling port on a first end of the cartridge member, a second one-way valve in communication with the sampling port, a stopper at a second end of the cartridge member, and a fluid chamber between the second one-way valve and the stopper; a body member having a first end configured to accept the first end of the cartridge member and a second end opposite the first end of the body member; and a cap unit disposed on the second end of the body member, the cap unit comprising a wash chamber, wherein the cap unit comprises a first one-way valve between the second end of the body member and the wash chamber and a filter between the first one-way valve and the wash chamber or a filter between the second end of the body member and the wash chamber and a first one-way valve between the filter and the wash chamber.

Abstract: The present invention provides simple and an accurate apparatuses for forming bilayer membranes by the contact of amphipathic monolayers. In one apparatus, amphipathic monolayers are brought into contact and fused by controlling the pressure of liquids introduced from microchannels forming an intersection containing a chamber. In another apparatus, the chamber includes a number of compartments and at least one construction portion. In this apparatus, a droplet is formed within each compartment and contact of amphipatic monolayers is accomplished by adjusting the size of the droplets.

Abstract: The present invention provides a simple and an accurate method of forming a bilayer membrane by the contact of amphipathic monolayers and an apparatus therefor. The method is characterized in that the organic solvent (2) containing lipid molecules is introduced into a first microchannel (1) formed on a substrate (5). A liquid (4) immiscible with the organic solvent (2) containing lipid molecules is introduced into a second microchannel (3), which crosses the first microchannel (1) from both sides to form an intersection, from both ends of the second microchannel (3) toward the intersection.
