Patent ID: 7878078

Claim:
A device for sampling particles comprising an elongated sampling support provided with housing means having a cavity on one side thereof for removably positioning at least one sampling substrate in the support, a longitudinal envelope surrounding the support to permit relative sliding contact engagement between the envelope and the support along a longitudinal axis through the device such that the support is able to slide in engaging contact with the envelope between a first sampling position in which the support extends outside the envelope, and a second position in which the support is confined to within the envelope with the support and the envelope consisting of materials having a low friction coefficient such that particle dust, if any, generated by sliding engagement between the envelop and support, is limited so that sampling is not changed by dust pollution from sliding engagement between the support and envelope; a handling rod connected to the proximal end of the support for manually controlling sliding movement of the support relative to the envelope, a gasket connected at the proximal end of the envelope for sealing the handing rod and envelope at its proximal end and connection means for sealing the distal end of the device when the support is confined to within the enclosure.
