A rugged SPME system and method for up-taking analytes, allowing injection of liquid samples in the field, providing better quantitation and reproducibility, and having higher capacity than other SPME devices that use a fiber, wherein the embodiments include a SPME stainless steel coiled wire sampler that may wick a liquid sample into the coil to thereby deliver a consistent quantity of liquid to an analyzer.

An aquatic particle sampling and collection apparatus comprising a tube within a tube cylindrical collection system wherein an inner tube is housed within an outer tube wherein the outer tube has a front end that is flared in a frustum shape to collect water. The inner tube defines an open chamber lined with a net or other collection apparatus which concludes with a conical cod end. An axial flow pump is situated within the collection system to facilitate the movement of water through the system thereby drawing particles in to be collected. The apparatus is paired with a subsea vehicle that allows for controlled collection and sampling. In various embodiments, the apparatus can be used to collect both bio particles such as plankton and non-bio particles such as plastics from the ocean. Where sampling is desired, the apparatus may include a disk after the conical cod end upon which the samples are collected.

There are prepared a first container which stores a liquid containing a cellular aggregate, a second container which receives a cellular aggregate, and a third container which stores a preliminary treatment solution, and a cylinder tip. The cylinder tip is formed with a syringe including a tubular passage having a front end opening which sucks the cellular aggregate, and a plunger which reciprocates in a tubular passage. Before sucking the cellular aggregate from the first container and discharging the same to the third container, the preliminary treatment solution is retained in a space between the tubular passage and the plunger by dipping the front end opening of the cylinder tip into the preliminary treatment solution in the third container and causing the plunger to reciprocate.

This disclosure is directed to a device and a system for aspirating and dispensing a target analyte, target material, or fluid. A picker may aspirate and dispense the desired material by introducing a pressure gradient. The picker may include a hydraulic fluid to hydraulically couple at least two components, such as a moveable pump component and a cannula.

A pressure testing module separable from and configured to be coupled with a tool base that is to be coupled along a downhole tool string to be conveyed within a wellbore extending into a subterranean formation. The pressure testing module includes a chamber and a piston assembly slidably disposed within the chamber, thus dividing the chamber into a first chamber portion and a second chamber portion. The piston assembly is operable to move in response to hydraulic fluid being pumped into the first chamber portion and to draw formation fluid of the wellbore into the second chamber portion in response to the movement of the piston assembly.

A sterile injector comprises a body having a cavity, a hollow needle positionable at a distal end of the injector, a probe holder receivable within the needle, a probe connected to a distal end of the holder, and a driving element axially displaceable within the cavity, for causing relative motion between the probe and the needle upon displacement of the driving element. A sample is injected into a sealed container by displacing the driving element to a first position causing the probe to extend from the needle, applying the extended probe with a sample, displacing the driving element to a second position causing the sample laden probe to be retracted within the needle, piercing a seal of a sealed container with the needle, and displacing the driving element to a third position distally spaced from the first position, after which the probe is injected into the container interior.

A system and method includes receiving at least one instruction from a first computing system to schedule a test of a fluid. An input device is operated for importing at least a quantity of the fluid from a source. A filling device is instructed for filling a vial with a pre-determined amount of the imported fluid. A drawing device is operated for drawing a pre-determined amount of a reagent. The drawing device is activated for adding the pre-determined amount of the reagent to the vial. An output of a photocolorimeter is read. The output indicates a reaction of the pre-determined amount of the imported fluid and the pre-determined amount of the reagent. A result of the test is transmitted to a second computing system.

The invention discloses a SMART, portable internet of thing (IoT) based device and/or system to monitor various key parameters automatically, in a given operating area or operating system in various application fields, which automatically performs multiple monitoring functions such as sampling, measuring, analyzing, reporting and stabilizing key controllable parameters and there auto-maintain these parameters as per desired level.
