Title: Device useful as a borehole fluid sampler

Abstract

The present invention provides a device comprising: (a) a proximal end of the device comprises an inner first conduit within the lumen of an outer second conduit, (b) a distal end of the device comprises the outer second conduit in fluid communication with a third conduit and a fourth conduit through a Y-shaped, T-shaped or U-shaped junction, (c) the third conduit terminates in a triggering mechanism, and (d) the fourth conduit is in fluid communication through a one-way valve, wherein fluid can only convey in a direction from the fourth conduit towards the second outer conduit, with an aperture.
