Methods and devices for testing a biological sample are provided. A tape includes multiple channels or reservoirs having inlet and outlet ports. One tape having biological sample disposed in its channels is temporarily mated with another tape having reagents disposed in its channels via a serpentine belt and compression roller assembly. Pulsed fluidic operations combine the reagents and the biological sample for subsequent observation, detection, storage and/or disposal. Fluidic transfer is provided in a uniform operation or in conjunction with a sensory feedback assembly.

Tissue sample cassettes for receiving tissue samples include an upper tray including compartments separated by dividers, a lower tray coupled to the upper tray and having a central recess, and an absorbent material located in the recess of the lower tray. Related systems and methods for automated gross processing of tissue samples are also disclosed.

An arrangement is provided that is configured to measure a biomarker value of an animal milk sample, including a cassette including a carrier tape having test zones indicating the biomarker value, and an inspective window. The carrier tape is disposed on first and second spools configured to cooperate with a cassette external motor. The arrangement also includes a service module including a camera configured to inspect the test zone, a motor configured to be engaged with a cassette spool, and a tube element configured to provide the milk sample to the test zone.

Condensation associated with the collection and identification of airborne particles is detected. Upon the detection, one or more condensation countermeasures are triggered to address the condensation.

An automated tape transfer apparatus including a tape feed mechanism feeding a continuous length of an adhesive tape through the automated tape transfer apparatus and a tape applicator applying the adhesive tape to a cutting face of a sample block, wherein a section of the sample block is adhered to the adhesive tape after cutting of the section from the sample block. A slide station transfers the cut section from the adhesive tape to a slide.

A slide station transfers the cut section from the adhesive tape to a slide.

A system for collecting and chemically analyzing water samples extracted from the soil to measure one or more analytes of interest such as soil nutrient levels of agricultural interest for increasing crop yield and quality in one use of the system. The system includes a sample collection probe (20) comprising a filter media (26) arranged to contact the soil when embedded therein and capture a water sample from the soil, and operably coupled to a sample processing sub-system (180) thereby collectively forming a sampling station (190). The sub-system (180) is configured to receive and analyze the water sample. A programmable probe controller (60) directs operation of the sample collection, processing, and chemical analysis in situ. A networked array (110) of sampling probes dispersed throughout the field may communicate wirelessly with at least one remote electronic device such as via the cloud computing (102). A modular version of a sampling probe (200) permits customized sampling at various soil depths.

Provided here are systems and methods for microtomy, including a microtome and a transfer tape system. The microtome can be used for sectioning a tissue section from a tissue block. The transfer tape system can include a transfer tape configured to adhere to a front face of the tissue block and collect one or more tissue sections sectioned by the microtome and to transfer the one or more tissue sections to one or more slides; and at least one tension device for controlling tension and an angle of the transfer tape relative the tissue block or the one or more slides. The at least one tension device can be configured to maintain the transfer tape at a predetermined tension or maintain the transfer tape at a predetermined angle relative to the tissue block or the one or more slides.

A diagnostic tester for analysing a body fluid includes a test tape having test zones configured to receive the body fluid. The tester further includes a chamber configured to contain the test tape and a seal. The tester further includes an opening of the chamber which is at least partially bordered by the seal. The tester further includes a face on the chamber that borders the opening, at least part of the face being formed by the seal. The tester further includes a closing leaf spring sealed onto the face, the closing leaf spring shielding the opening from an environment outside the chamber. The tester further includes an exit gap formed between the closing leaf spring and the seal through which the test tape is configured to exit the chamber.

Disclosed is plate or film for collecting and analyzing a sample. The plate or film includes a surface and a plurality of slices from the sample immobilized on the surface. Further, the plurality of slices are cut from the sample with equal thickness, and the plurality of slices are placed on the surface of the plate or film following their cutting order.
