A fiber optic analyte sensing needlewith a photoluminescent analyte-sensitive probenonadherently entrapped within the lumenof the needlebetween the distal tipof a fiber optic filamentand the distal tipof the needle. The probehas unimpeded fluid communication with the external environment through a portin the needle

An assembly and method of using the assembly. The assembly is operable when assembled as a benchtop instrument for sealed penetration of an oxygen sensitive luminescent sensor into sensible communication with an enclosed space of a sealed rigid package to measure oxygen concentration therein, and operable when disassembled as a handheld instrument for sealed penetration of the oxygen sensitive luminescent sensor into sensible communication with an enclosed space of a flexible package to measure oxygen concentration therein. The assembly includes a mechanical punch press equipped with a longitudinally reciprocable fixture equipped with a hollow piercing member, and an oxygen analyzer releasably attachable to the fixture.

A garden hose support assembly for holding a garden hose above ground includes a hold attached to a support. The hold forming a receiving space for receiving a hose. The hold includes a first arm, a second arm and a middle arm extending between and being attached to the first arm and the second arm. The first arm and the second arm are angularly positionable relative to the middle arm. A plurality of rollers is provided. Each of the first arm, the second arm and the middle arm has one of the rollers positioned thereon. The rollers are rotatable with respect to the hold. A mount is attached to a distal end of the first arm relative to the middle arm. The mount engages a vertically oriented surface such that the hold extends laterally away from the vertically oriented surface.

A calibration tool and method of using the tool to calibrate a fiber optic needle oxygen sensor. The tool includes at least a vial sealingly covered by a septa and containing a supply of particulate oxygen getter within the chamber of the vial. The vial has an open top and is constructed from an oxygen impermeable material. The septa is resealing, needle-penetrable and oxygen impermeable. The supply of particulate oxygen getter is retained within an oxygen permeable sachet.

Calibration vial and technique for calibrating a fiber optic oxygen sensing needle

A fiber optic analyte sensing needle employing an analyte-partial-pressure-sensitive photoluminescent probe, characterized by (i) a void volume channel extending axially along the length of the lumen between the inner surface of the tube and the outer surface of the fiber optic filament, and (ii) a total pressure sensor in pressure communication with the distal tip of the needle via the void volume channel, whereby total pressure of a volume sampled by the sensing needle can be routinely measured and used in pressure compensation of analyte-concentration values calculated from the analyte-partial-pressure readings taken from the analyte-partial-pressure-sensitive photoluminescent probe.

A photoluminescent oxygen probe including a tack with a layer of a pressure-sensitive adhesive and an oxygen-sensitive photoluminescent element on the underside of the head. The probe is effective for sensing oxygen concentration within an enclosed space by puncturing the container defining the enclosed space the with the probe's shank and adhering the underside of the probe's head to the container so as to sealingly surround the puncture, thereby placing the oxygen-sensitive photoluminescent dye on the underside of the probe's head into sensible communication with the enclosed space through the puncture hole.
