A device for characterizing the biological properties of cells can include a plurality of dual-compartment assay chambers wherein the compartments of each chamber are separated by a cell layer across which ions can flow. The biological properties of the cell layer in the presence or absence of experimental compounds can be determined by measuring an electrical gradient across the layer. A individual dual-compartment chamber of this type may be referred to as an “Ussing chamber.”

Systems and methods for monitoring laboratory animals includes a tag comprising an inductive element and a capacitive element attached to a portion of a laboratory animal. The position of the portion is detected by monitoring the effect of the tag on a time-varying magnetic field having different frequencies, one near tag resonance, and one away from tag resonance.

Disclosed herein are apparatuses and methods handling a portion of a tissue sample when sectioned by a microtome. The apparatuses include a container, a tissue sample holder in the container, and one or more outlets configured to allow flow of a fluid from the container. the flow through the outlet causes a portion of the tissue sample sectioned by a microtome to move into the outlet. The methods include sectioning one or more portions of a tissue sample, and flowing a fluid past the tissue sample to cause the one or more portions of the tissue sample to move away from the tissue sample and toward at least one fluid outlet.

Methods and devices for inline sampling of a bulk material, such as a powder, are provided. The material's bulk density can be determined from samples drawn using methods and devices described herein. One embodiment of a method of sampling a material allows the material to flow through a sampling compartment, closes off the flow of material below the sampling compartment, builds up a column of material through the sampling compartment, shifts the sampling compartment to remove a slice of material in the column, and places the slice of material into a sample container. A device for sampling a material is provided in another embodiment. The device includes an inlet, an outlet aligned with the inlet, and a sample collector. The sample collector can include at least one through hole and be configured to move such that the at least one through hole can be moved into and out of alignment with the inlet and the outlet.
