Abstract
The present invention generally relates to devices, systems, and methods for acquiring and/or dispensing a sample without introducing a gas into a microfluidic system, such as a liquid bridge system. An exemplary embodiment provides a sampling device including an outer sheath; a plurality of tubes within the sheath, in which at least one of the tubes acquires a sample, and at least one of the tubes expels a fluid that is immiscible with the sample, in which the at least one tube that acquires the sample is extendable beyond a distal end of the sheath and retractable to within the sheath; and a valve connected to a distal portion of the sheath, in which the valve opens when the tube extends beyond the distal end and closes when the tube retracts to within the sheath.
