An apparatus for carrying well samplers including a tubular carrier housing, a crossover sub connected to the housing, and a pair of adjacent single phase samplers set off from the tool centerline axis thereby providing an offset interspatial through-bore region to support wireline operations. The pair of single phase samplers are removably disposed between upper and lower positioning inserts. The inserts have recessed sampler seats and through-bores that align with the interspatial through-bore region. A conduit fluidly connects one pair of recessed seats to the tool exterior so as to port annulus pressure to the pressure-activated triggering mechanisms of the samplers. A rupture disk housing is removably connected to the triggering conduit from an exterior recess in the crossover sub. The other positioning insert includes a clamping mechanism to removably secure the samplers within the carrier. Multiple assemblies of crossover subs and carrier housing can be connected in tandem.
