The present disclosure provides a biological fluid collection device, such as a blood collection device, that is adapted to receive a multi-component blood sample having a cellular portion and a plasma portion and quickly, efficiently and cost-effectively separate the plasma portion from the sample. A pressure gradient can be applied across a separation member to facilitate movement of the plasma portion ahead of the cellular portion. The present disclosure allows for both passive and active plasma separation and dispensing.

A biological fluid collection device that receives a sample and provides flow-through blood stabilization technology and a precise sample dispensing function for point-of-care and near patient testing applications is disclosed. A biological fluid collection device of the present disclosure is able to effectuate distributed mixing of a sample stabilizer within a blood sample and dispense the stabilized sample in a controlled manner. In this manner, a biological fluid collection device of the present disclosure enables blood micro-sample management, e.g., passive mixing with a sample stabilizer and controlled dispensing, for point-of-care and near patient testing applications.

This system takes in raw cellular material collected using a provided swab, blood collection device, urine collection device, or other sample collection device and transforms that biological material into a digital result, identifying the presence, absence and/or quantity of nucleic acids, proteins, and/or other molecules of interest.

Fittings for capillaries, such as those in chromatographic systems, can be difficult to reliably assemble. The invention relates to a connector for providing a fluid connection between a capillary and a fluid conduit, said connector comprising: a capillary holder for receiving an end of the capillary, said capillary comprising inner capillary tubing, wherein the inner capillary tubing of the received end of the capillary is located within a compliant material sleeve; a deformable portion configured for deforming so that the compliant material of the sleeve in the capillary holder is deformed to create a seal between the inner capillary tubing and the connector; and a receiving portion configured to receive a fitting at an end of the fluid conduit; wherein the capillary holder and the receiving portion are connected so that the connector is configured to fluidly connect the capillary and the fluid conduit.

Disclosed herein are systems and methods for serial flow emulsion processes. Systems and methods as described herein result in reduced cross-contamination.

A receptacle includes an upper portion having a cylindrical portion and an open end and a lower portion depending from the upper portion, where the lower portion is tapered and has a closed bottom end. The receptacle may include a radially-extending annular ring with a flat or sloped bottom surface and disposed on an outer surface of the receptacle at a transition between the upper portion and the lower portion and/or a radially-projecting lip circumscribing the open end, which may be configured for inter-locking engagement with a mated cap inserted into the open end of the upper portion. Embodiments may include one or more longitudinally-oriented grooves formed in an inner surface of the upper portion. The receptacle may be a unitary plastic structure.

In a pipette tip that is open at opposite distal and proximal ends, a glass tube has a first end adjacent to the distal end, a second end adjacent to the proximal end, and a first through hole extending therethrough from the first end to the second end. A connecting member has a second through hole with the glass tube inserted therein. The glass tube is at least partially inserted in the second through hole on one side adjacent to the second end, and is entirely located outside the second through hole on the other side adjacent to the first end. A diameter of an end portion of the connecting member opposite the distal end is greater than a diameter of the distal end of the pipette tip, and the connecting member is made of resin.

A sampling device comprises a handle and a collector. The collector is connected to the handle. The collector has a capillary function and is able to automatically suction a liquid reagent or sample. The sampling device is able to suction a required amount of the reagent or sample quickly, conveniently and quantitatively. The sampling device can be product conveniently, and may achieve micro-quantitative sampling. The reagent is stored in the collector of the sampling device in the form of a dry powder, which may achieve the individual packaging of the detection reagent.
