Method for transferring one or more portions of fluid from a specimen tube, comprising: providing an elongate connector comprising an elongated tube having a lumen or through-hole extending between proximal and distal ends thereof, a Luer-compatible female taper provided on the proximal end of the connector, a flange provided proximate the distal end of the connector; providing a tube seal mounted on the distal end of the connector, the tube seal comprising an elastomeric member having a longitudinal axis, a proximal end, a distal end, and a through-hole extending therebetween, the distal end having a frustoconical or chamfered face forming a funnel, the elastomeric member having an outer diameter sized to sealingly engage with an inner surface of the specimen tube; advancing the distal end of the connector and the tube seal into the specimen tube, the funnel directing the first layer into the through-hole of the connector.

A microfluidic device and method of assaying for immune cell exhaustion therewith are provided. The microfluidic device includes a moveable rod positioned across a chamber of a microfluidic device adjacent a first end thereof. Target cells are mixed into a hydrogel and the hydrogel is injected into the chamber about the moveable rod. The hydrogel is polymerized in. the chamber and the moveable rod is removed from the hydrogel so as to form a passageway in the hydrogel. The passageway is filled with a solution including immune cells. The immune cells migrate/diffuse into the hydrogel. A gradient of nutrients is formed in the chamber from. the first end to a second end of the chamber. One or more biopsies of the hydrogel may be taken at user selected location(s) of the chamber.

A device for extracting plasma from a fluid collection tube comprising: a tubular barrel having sidewall surrounding a lumen which extends between proximal and distal ends thereof, the tubular barrel forming a tip at a distal end; a barrel seal movingly seated within the lumen of the tubular barrel, the barrel seal closing and sealing the proximal end of the tubular barrel; a tube seal having a proximal end, a distal end, and a lumen extending therebetween, the proximal end having a frustoconical or chamfered face, the tube seal having an outer diameter sized to sealingly engage with an inner surface of the fluid collection tube, and an inner diameter sized to sealingly engage with an outer surface of the tip of the tubular barrel, the tube seal mounted on the tubular barrel such that the tip of the tubular barrel extends into the tube seal lumen.

The present invention describes several embodiments of a device that allows for the supporting, storage and deployment of large surface area thin film solid phase microextraction (TF-SPME) chemical samplers from within a sample fluid carrier. The utility of said supporting device originates from the process by which the extraction surface is stabilised within a sample carrying fluid for the extraction of chemical molecules from said sample carrying fluid. The device is also characterized by having a seating cavity, and moving mechanism or cap that can switch the supported TF-SPME chemical sampler between an open, sampling position or closed storage position.
