  • Sample collector for particulate material and method
    Patent number: 12474313
    Abstract: A sample collector for extracting a particulate material specimen from a container includes a needle for puncturing the container and capturing an amount of specimen inside a chamber in mechanical communication with the needle. A spring-loaded continuously and progressively retractable and extendable sheath protects the tip of the needle from inadvertent contact with a human user and encloses the puncture site on the container during collection. A preliminary screening test for illicit substances can be conducted on part of the collected specimen to determine whether the container should be confiscated. Part of the collected specimen can be preserved for later confirmatory testing.
    Type: Grant
