The invention provides a sampling device for geological fluid detection, relates to the technical field of fluid detection. The sampling device comprises a support frame, the support frame is of an L-shaped structure, and a second support plate is arranged above the support frame; the protection cover is mounted at the corner of the bottom of the support frame. The water fixing cone is clamped above the support frame; the locking inclined block is mounted at the upper part; and the detector is provided with a water inlet pipe. Fluid at different depths is detected through cooperation of the mounting sleeve and the lifting frame, a fluid drainage tube is wound through the winding wheel, the mounting sleeve is driven by the lifting frame to adjust the position through the arrangement of the gear and the rack, the fluid is sampled through the sampling test tube.

An open-cell foam structure that is impregnated with a disinfectant and used to remove pathogens from air, water, and surfaces, and kill the pathogens

A removably attachable sampling and analysis apparatus for use with a drone which includes a housing member, a flotation member, at least two connecting members, a collapsible framework and sensors. A preferred embodiment of the present invention enables rapid deployment of the sampling and analysis apparatus to multiple target locations on a body of water to take water quality measurements and samples. The sampling and analysis apparatus can also be utilized in other applications such as soil measurements and sample collection, agricultural and forestry applications, as well as with gas sensors to measure air quality and map values in 3D space with a time stamp.

An open-cell foam biological indicator for bacteria detection and removal from water or air, and methods of use.

A blended powder sampling thief for sampling a powder includes an elongated rod that has an upper portion and a lower portion. The lower portion defines at least one cavity. A tubular sheath is disposed about the rod and is slidable between a lower position in which the tubular sheath exposes the at least one cavity and an upper position in which the at least one cavity is exposed. When the rod is inserted into the powder and the tubular sheath is in the upper position, the powder flows into the at least one cavity. When the tubular sheath is slid into the lower position, a sample of the powder is entrapped in the at least one cavity so that when the sampling thief is removed from the powder, the sample of the powder will remain in the at least one cavity.
