  • an outer sheath;

    a plurality of tubes within the outer sheath, wherein 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, wherein a distal end of the at least one tube that acquires the sample is independently extendable relative to the at least one tube that expels the immiscible fluid to a position beyond a distal end of the outer sheath and independently retractable to a position within the outer sheath; and

    a valve connected to the distal end of the outer sheath, wherein the valve opens when the distal end of the tube that acquires the sample extends beyond the distal end of the outer sheath and closes when the distal end of the tube that acquires the sample retracts to within the outer sheath.
