A medical swab comprising a thin stick comprising a drawn plastic stick and a sphere-like fiber lump formed on at least one end of the stick. The fibers are chemically treated to enabled a color change when exposed to moisture. On the thin stick, a unique identifier sticker or tab is placed on the swab. A cover is slidably attached and there is a slide stop located near the head or collection area. The cover has an egg shape and split design where the cover is comprised of two equally sized pieces connected by a small hinge portion. The cover has a plurality of holes which allow odor to escape from the cells or material collected on the swab. When in the closed position the clips act as a clasp, which locks the cover in place, creating a cage around the head or sample end.

A plurality of caps are provided each with a visual coding of color and/or indicia for use with different sizes of bottles at least in accordance with a height of the bottles from a closed bottom end to an open top end for engaging each of the caps. Each of the caps has a tube mounted to, or through, an aperture extending through a top closed end of the cap to extend a selected length enabling one end of the tube to reach or extend along an interior surface of the bottom end of any of the bottles of the height to which the cap is coded for use therewith. The other end of tube is extendable to a bioreactor container. Each of the caps has another tube or port to another aperture of the cap to provide an air vent with an optional air filtering device.

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.

A system for separating biological material includes a centrifuge tube, a separation tube having an open bottom, a cap, and a separation medium disposable within the centrifuge tube and the separation tube. The centrifuge tube and the separation tube sealingly and releasably couples to the cap, such that, when coupled, the separation tube is positioned within the centrifuge tube. The cap is configured to facilitate and/or regulate air- or gas-flow between an area outside of the cap and an interior of the separation tube. When the separation tube is positioned within the centrifuge tube, the open bottom of the separation tube is submersed in the separation medium. The system also includes a hollow needle coupled to a means for regulating a flow of air, gas, or other matter. The needle is insertable through the cap or plug, and is used to facilitate the introduction of matter into the separation tube.

A liquid handling system and method, e.g., for testing blood samples. The system comprises a cartridge, and a transfer device couplable to a liquid reservoir. The cartridge comprises compartments with an inlet, closed by a seal, and an outlet, closed by a gas-permeable liquid-tight filter. Keying portions define a relative position and orientation of the cartridge and the transfer device. Penetrating elements of the transfer device penetrate the seal of each compartment, the penetrating elements having lumina for fluidly connecting the reservoir and each compartment cavity of the cartridge.

The present disclosure provides a digital PCR system. The system includes a droplet formation assembly and a droplet orifice assembly. The droplet formation assembly includes a heat conducting plate and a cover plate, at least one inverted U-shaped step is placed on a side surface of the cover plate, the heat conducting plate, the cover plate and the inverted U-shaped step together form a droplet formation chamber having an opening at a bottom. The droplet orifice assembly is connected below the droplet formation assembly, and includes a plurality of droplet orifices, the droplet orifice is connected with the droplet formation chamber, and a vaporization component is placed in the droplet orifice, the vaporization component vaporizes a digital PCR solution in the droplet orifice and rapidly pushes the digital PCR solution into a droplet forming oil in the droplet formation chamber, to form a digital PCR droplet.

A specimen cap. The specimen cap allows material to be transferred out of a specimen cup without exposing the user (clinician, lab tech, phlebotomist) to the sample. The cap employs a double cap system with a secondary cap providing access to a needle holder that holds a needle assembly. The needle assembly has an upward extending needle, with an optional needle cover, and a downward extending draw or sample tube extending downward to reach the sample contained in the specimen cup.

Provided is a tip set used for a genetic testing device. The tip set includes a piercing tip breaking a lid portion of a reagent container filled with a reagent to open the reagent container and an injection tip injecting a sample solution containing a target gene nucleic acid into a microchip. The injection tip has a reservoir storing the sample solution in an internal space and an injection needle protruding from the reservoir, an opening the internal space to a side opposite to the injection needle is formed in the reservoir, and the piercing tip has a fitting portion fitted to the injection tip to connect the injection tip and the piercing tip.

A blood testing assembly and method are described. In the method, a blood testing device having a plasma separation membrane and a reagent is connected to a syringe containing blood having blood cells and plasma. A blood sample of the blood is passed from the syringe through a plasma separation membrane within the blood testing device to separate the plasma from the blood cells. A reagent is saturated with the plasma, and then the reagent is colorimetrically analyzed to determine a degree of hemolysis within the blood sample.
