  • Publication number: 20220401172
    Abstract: The invention relates to an assembly comprising a sampling device with a rod and a swab and a transfer tool for detaching the swab from the rod and transferring the detached swab to a container. The transfer tool comprises a housing enclosing a closed chamber having a swab-member passage and configured for receiving the swab-member. The housing comprises a first housing part and second housing part hinged to the first housing part. The first housing part and second housing part define an entry opening to a channel delimited by the first and second housing part. This channel extends from outside the housing to the passage. The first housing part and second housing part are rotatable around the hinge between a holding condition and a non-holding condition. The swab-member passage is configured to prevent, in holding and non-holding condition, the base from entering the passage whilst allowing, in non-holding condition, the swab member to pass through the passage.
