An extraction system for testing microbial contamination includes a biocompatible outer vessel that has a side wall and a biocompatible suspension system that is positionable within an interior of the biocompatible outer vessel. The biocompatible suspension system includes a horizontal member on which a sample may be supported and a securement mechanism that is engagable with the side wall of the biocompatible outer vessel to maintain the suspension system at a desired position within the biocompatible outer vessel.

Agricultural systems have increased in complexity to allow farmers to control the environmental factors impacting a crop. By analyzing data from a plurality, and preferably a large number, of operations, a particular objective for a particular plan may be developed for a particular crop. The equipment at a particular site may then monitor the crop and be controlled by a device, such as an on-site hub, to operate equipment in a manner associated with the particular plan and objective.

A system for collecting tissue samples, such as meat tissues on carcasses, for example in the food industry. Also provided are methods for collecting tissue samples, and to a non-transitory computer-readable medium comprising program instructions to execute at least one step of the method for collecting tissue samples.

A method of sampling a multi-layered material and a micro-sampling tool are described. The sampling method includes penetrating a top surface of a material in a component of interest with a micro-cutting tool to a predetermined depth sufficient to include each layer of the multi-layered material and a portion of the base, without cutting through the full depth of the base, undercutting from the depth of penetration through the base to define a micro-sample of the multi-layered material, and removing the micro-sample with each layer of the multi-layered material intact. The micro-sampler includes a cutting tool calibrated to cut to a depth no greater than 2 mm, and in some aspects, no greater than 200 microns into a multi-layered material, the material having a top surface and a metallic or ceramic base and a container for removing and storing a micro-sample cut from the material with each layer of the multi-layered material and a portion of the base intact.
