The present disclosure provides systems, methods, devices, and kits for analysis of vaginal biological samples. A device for the analysis of vaginal biological samples can include a sample collector, an extractor, and an assay cartridge. A method for the analysis of vaginal biological samples can include detecting the presence or absence of a pathology, a disease, an immune disorder, a reproductive disorder of a subject. The method may further comprise preserving, storing, or transporting the vaginal biological samples. A kit for the analysis of vaginal biological samples can include probe, reagents and instructions for detecting a nucleic acid in the vaginal biological samples.

The invention relates to a method and system for performing VPD-DC on wafer surfaces, wherein the pipette substitutes for the function of the scan tube and is operated such that a bulge of scanning liquid protrudes from the pipette channel and contacts the wafer surface for scanning.

Embodiments generally relate to a device for housing chemical vapour sampling material. The device comprises a housing comprising a barrel, the barrel being configured to hold at least one fibre of chemical vapour sampling material, the barrel having a first opening at a first end configured to deploy at least a portion of the at least one fibre of chemical vapour sampling material; an extension mechanism arranged to cause extension and retraction of the at least one fibre of chemical vapour sampling material from the housing via the first opening; the extension mechanism being operable by actuation of at least one actuator. Actuating the at least one actuator causes extension or retraction of the at least one fibre of the chemical vapour sampling material from the housing via the first opening.

A picktool manipulator device collects a specimen from a culture medium. In a first mode of operation, a picktool is allowed to move in an axial direction relative to support structure of the device. A detector may generate a signal in response to movement of the body in the axial direction so as to determine a height at which the picktool contacts the medium. The device may operate in the first mode when collecting a specimen from a culture medium. A second mode of operation constrains or precludes axial movement of the picktool. In some cases, the device may operate in the second mode when receiving a new picktool or discarding a used picktool.

An extraction apparatus is a sample removal apparatus that removes a sample collected from a living body. The extraction apparatus includes: a storage container holder that holds a storage container of a sample and is capable of being placed at a sample receiving section where the sample is supplied to the storage container, and a removal section that causes the sample to be discharged from the storage container to a predetermined place; a housing that covers the storage container holder and the removal section; and a supply section that allows for supply of the sample from the outside of the housing to the storage container in the housing.

An apparatus for testing a fluid sample including a sample receiving member having an opening for receiving a fluid sample, wherein the sample receiving member comprises at least a first and second sample collection chambers, a sample retention member, in fluid communication with the first sample collection chamber, to retain a portion of the fluid sample, and at least one test strip, in fluid communication with the second collection chamber, to indicate the presence or absence of at least one analyte in the fluid sample, wherein the first collection chamber is not in fluid communication with the second collection chamber.

Disclosed is a salinity detection device. The salinity detection device has a collection plate, a mounting frame, and a sensor portion including a predominantly non-metallic sensor. The device may be mounted in a wheel well of a vehicle via the mounting frame and the collection plate may be attached to the mounting frame and positioned behind a wheel such that water on a road surface may be splashed thereon. The collection plate is fluidically connected to the sensor portion so that water may flow through the sensor portion proximate the sensor to measure a current flowing through the water and determine a salinity thereof.

Article for sampling comprising inner layer, one or more outer layers, and optional scouring layer on a portion of the one or more outer layers.

Methods for product authentication, which include: providing an article having a substrate with an analyte encoded composition; obtaining a sample of the composition; applying the sample to a test device to obtain test results, analyzing test results from the test device using an electronic device communicatively connected to an authentication authority, wherein the electronic device transmits the test device code and the test results to the authentication authority and confirms or denies authentication after comparison to an authentication database of authentic test results.

Devices, systems, and methods are disclosed which relate to using a use large area surface sampler with invertible bag for collection of biological and non-biological particles prior to subsequent analysis. The large area surface sampler with invertible bag uses an inverted bag with bonded sampling material to first serve as a sampling device followed by the bag being turned right side out and the captured particles being extracted inside of the bag. The device includes measures for sealing liquid in the sampling material using a protective cup at time of manufacture. This enables users to simply remove the protective cup and perform wet surface sampling prior to turning the bag right side out and removing captured particles from the sampling material with repeated compressions. The described device, systems and methods allow users to capture and elute surface samples for human clinical, veterinary, food safety, pharmaceutical, outbreak investigations, forensics, biodefense and bioterrorism response, environmental monitoring, and other applications where collection of samples from surfaces and humans or animals is required.
