Provided is a cell isolation instrument capable of smoothly performing a plurality of steps associated with isolation of cells, including gripping of a biological tissue, transferring of the biological tissue, and isolating of the biological tissue. A container has an opening. A sealing member seals the opening. A pair of pinching parts is connected to the sealing member, and the pair of pinching parts opens or closes by being pressed.

A container (1) for biologic samples has a lower receptacle (2), an upper receptacle (3) for a toxic liquid (LF) or considered as such, having a radial ring (63), and a connecting sleeve (4) with a circumferential rim (54) and a transversal septum (40), provided with a central vent opening (55) and with a plurality of transfer openings (51) for the transfer of toxic liquid (LF). The toxic liquid (LF) is sealed between the upper receptacle (3) and the transversal septum (40) before unscrewing the upper receptacle until its radial ring (63) touches the circumferential rim (54). When unscrewing the upper receptacle (3), the toxic liquid (LF) reaches and passes through the plurality of transfer openings (51), and air contained in the lower receptacle (2) flows into the upper receptacle (3) through the central vent opening (55), without any exit of gases and liquids from the container (1).

The disclosure relates to devices, solutions and methods for collecting and processing samples of bodily fluids containing cells (as well as embodiments for the collection, and processing and/or analysis of other fluids including toxic and/or hazardous substances/fluids). In addition, the disclosure relates generally to function genomic studies and to the isolation and preservation of cells from saliva and other bodily fluids (e.g., urine), for cellular analysis. With respect to devices for collection of bodily fluids, some embodiments include two mating bodies, a cap and a tube (for example), where, in some embodiments, the cap includes a closed interior space for holding a sample preservative solution and mates with the tube to constitute the (closed) sample collection device. Upon mating, the preservation solution flows into the closed interior space to preserve cells in the bodily fluid. The tube is configured to receive a donor sample of bodily fluid (e.g., saliva, urine), which can then be subjected to processing to extract a plurality of cells. The plurality of cells can be further processed to isolate one and/or another cell type therefrom. The plurality of cells, as well as the isolated cell type(s), can be analyzed for functional genomic and epigenetic studies, as well as biomarker discovery.

An analysis device and an analysis apparatus for identification of analytes in fluids applying the SERS effect which provides a safe way to perform analysis, avoiding an accidental cross-contamination without the use of disinfectant products; the analysis device comprising a casing enclosing a sample region for receiving a fluid sample, and a nanoparticle region for storing at least a nanoparticle fluid; the sample region and the nanoparticle region being in fluid communication each other through a passage; driving means in fluid communication with the passage; a mixing region in fluid communication with the passage; and the casing being adapted to allow an incident monochromatic light from an external source to strike on the mixing region, and a reflected light from the mixing region to leave the casing.

An embodiment provides an apparatus, including: a cartridge including a base and a lid; at least one fluid line located between the base and the lid of the cartridge; at least one heating element located either on the base or the lid and aligned in intimate contact with the at least one fluid line; at least one heat sensing element in intimate contact with the at least one fluid line, where the at least one heat sensing element is spaced downstream from the at least one heating element; a supply of power to the cartridge; and a processor in electrical communication with the cartridge that executes a program of instructions to: operate the at least one heating element to produce heating of the at least one fluid line at a first position; and operate the at least one heat sensing element to detect the heat of a fluid within the at least one fluid line at a position downstream of the first position. Other embodiments are described and claimed.

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.

A tube for mixing, diluting and preserving a sample includes a hollow first container for receiving and storing a solution, the first container having first and second ends, wherein at least the first end has a through-hole, and a transport-pin located in the through-hole of the first end having a shape closely matching to the through-hole, the transport-pin including a recess with a predetermined size. The recess is suitable to be filled by a sample, wherein the transport-pin is movable between an initial position in which the recess is positioned at least partially on the outer side of the first container, and an end position in which the recess is positioned at least partially on the inner side of the first container.
