In one configuration, a handheld compound tester to process and detect presence of a compound in a tablet is disclosed. The handheld compound tester may include a sampling chamber configured to receive a tablet and a lid couplable with the sampling chamber. The coupling of the lid with the sampling chamber may cause cutting of the tablet. A liquid may be added inside the sampling chamber to create a mixture with segments of the tablet. The mixture may be then received by a housing adjoining the sampling chamber. A test strip disposed within the housing, upon contacting the mixture, may be configured to indicate a presence of the compound in the mixture.

An apparatus for individually storing multiple tissue samples separately from each other includes a base, a lid, a lock, and one or more vents. The base defines a plurality of reservoirs and a plurality of identification areas. A portion of the base defines an opening corresponding to each reservoir. The lid is configured to secure the multiple tissue samples within a corresponding reservoir by enclosing each corresponding opening in the closed configuration. The lock is configured to selectively lock the lid against the base in the closed configuration. The one or more vents are configured to enable entry of fluid into the reservoirs when the lid is in the closed configuration. The one or more vents are further configured to prevent exit of tissue samples from the reservoirs when the lid is in the closed configuration.

There is provided a sample processing cartridge comprising a. a sample entry location; b. a closed sample processing chamber; c. a sample analysis location comprising a sample analysis well; d. a first channel fluidly connecting the sample entry location and the sample processing chamber; e. a second channel connecting the sample analysis location and the sample processing chamber, the second channel comprising a closed or closable second channel valve; wherein the sample processing chamber comprises a second channel port providing fluid connection between the second channel and the sample processing chamber, the second channel port being positioned in a sample accumulating region of the sample processing chamber. There is also provided a sample processing system comprising the cartridge, and methods of use of the cartridge and processing system in a sample processing assay.

Embodiments described herein relate to an apparatus for positioning and securing an excised biological tissue specimen for imaging and analysis. In some embodiments, an apparatus includes a sample bag defining an inner volume configured to receive a biological tissue sample, and a sealing member coupled to the sample bag. An imaging window is disposed and configured to be placed in contact with at least a portion of the biological tissue sample, and a positioning member is coupled to the imaging window and is configured to be disposed against the sealing member to substantially seal the inner volume. The positioning member includes a vacuum port disposed and configured to be aligned with a vacuum source to withdraw air from the inner volume of the sample bag.

A detection chip is disclosed. The detection chip includes a sample injection structure, a filter structure, and a reaction structure which are sequentially connected. The filter structure includes a first main body, and a first inlet portion and a first outlet portion respectively on two sides of the first main body. A width of the first inlet portion gradually decreases in a direction away from the first main body, and a width of the first outlet portion gradually decreases in a direction away from the first main body.

A pipette tip according to certain embodiments includes a proximal end, a distal end, and a reagent chamber. The proximal end is dimensioned to fit on an end of a pipettor, and includes a proximal end opening. The distal end includes a distal end opening. The reagent chamber has a reagent composition disposed therein. The reagent chamber is defined at least in part by a proximal barrier and a distal barrier. The reagent composition is operable to pass through the distal end opening upon rupturing of the distal barrier.

An embodiment of the present disclosure provides a liquid collector that collects liquid, the liquid collector including: a flow passage member including a flow passage that connects one end and other end of the flow passage member; a contact member that is disposed at the one end of the flow passage member, that includes an elastic material, and that is configured to come into contact with a target from which liquid is to be collected; and a container that receives the liquid discharged from the flow passage at the other end of the flow passage member.

An improved biological sample preparation device and method of using the device. The disclosed device provides improved sample volume control, reduces potential contamination in the working environment, increases ease of use, and improves safety for healthcare workers.

The disclosure relates to a container for filtering a suspension which comprises a lid and a vessel. The container comprises a filter that divides an interior space of the container into a first compartment and a second compartment. The lid comprises a first access and a second access. The first access is connected to the first compartment, and the second access is connected to the second compartment.

A process for freeze drying a material. The process has the steps of (a) placing material to be freeze-dried in a vessel, the vessel comprising a container having a base, and at least one wall defining an opening at one end; (b) applying a membrane to the at least one wall to thereby cover the opening, wherein the membrane comprises an aperture which, in use, is aligned with the opening; and (c) subjecting the vessel to a lyophilisation procedure, wherein the membrane is in place on the container during the lyophilisation procedure.
