A testing system collects a specimen from a subject and measures the collected specimen to test the specimen, and includes a box to allow at least one of specimen collection for collecting and receiving the specimen, preprocessing for processing the collected specimen before measurement, or specimen measurement for measuring the preprocessed specimen to be performed therein.

The present invention provides devices and methods for generating a pulsatile fluid flow in a microchannel by means of external actuation of a thin flexible film. With the devices described herein, cycles of positive and negative actuation can be used to infuse or withdrawal fluid in a microchannel. Fluid can be recirculated over one or more microfluidic feature, such as a chemical or molecular receptor, biosensor, electrode, cell or biological material, chromatography feature, mixer, etc., in a way that would represent an advantage over the single-pass flow techniques common to most microfluidic devices. The devices and methods are particularly useful in vitro diagnostics (IVD), analytical chemistry, chromatography, and mixing applications in a variety of fields.

The present disclosure relates to a single cell analysis system. Disclosed herein is an instrument for single cell processing. The instrument comprises: a motor component; a processing component, which comprises a processing chamber inside and multiple first connecting holes; a container, which comprises a sample collecting reservoir, a waste collecting reservoir, multiple sample loading reservoirs, multiple first microchannels, and a second microchannel; a chip, which is connected under the container and forms a gap with the container, the chip comprises a third microchannel, the bottom of the third microchannel comprises a microwell array; a snap component comprises a feeding beam and a snap body, and a first end of the feeding beam connects to the snap body and a second end of the feeding beam connects to the motor component; and a pneumatic component which connects with the multiple first connecting holes.

A wash station for use in a clinical analyzer of an in vitro diagnostics (IVD) environment for cleaning a probe comprises a basin, a vertically-elongated conduit, an inlet port, and a helix insert. The vertically-elongated conduit is attached to the interior of the basin. The inlet port is connected to a bottom portion of the basin. The inlet port is sized to receive and secure a wash feed line that propels a wash fluid upward through the vertically-elongated conduit. The helix insert is positioned within the vertically-elongated conduit and sized to allow insertion of the probe through a center portion of the helix insert for cleaning. The helix insert causes the wash fluid to flow in a helical shape around the probe as it is transported through the vertically-elongated conduit, thereby cleaning the probe.

Systems and methods for probe tip heating are disclosed. An exemplary system for probe tip heating can include an enclosure enclosing a probe tip, a heating device, and a fan. The probe tip can be configured to access an internal volume of a stoppered container and to aspirate or dispense a material from or to the internal volume of the stoppered container. The heating device can be configured to heat air circulating within the enclosure. The fan can be positioned to circulate air within the enclosure to heat the tip of the probe

A soil fractionation system can include a plurality of sample racks propelled by a drive system. Each sample rack can include a sample tube for holding a soil sample and a filter cup for receiving an extracted fraction of the soil sample. An extractor module of the fractionation system can include an extractor assembly and a filter assembly. A control system can control the relative positioning of the plurality of sample racks via the drive system, the relative movement between the extractor assembly and the sample tube, and the relative movement between the filter assembly and the filter cup.

Disclosed is an automated liquid-phase immunoassay apparatus used with a cuvette having a plurality of chambers containing a reagent necessary for detection of an analyte in a biological specimen. The apparatus includes a movable cuvette module equipped with the cuvette, an optical reading module for optical assaying of a material resulting from a reaction between the specimen and the reagent, and a dispenser module which is positioned on the cuvette module and which dispenses the specimen and the reagent to the plurality of chambers of the cuvette and washes the specimen and the reagent therefrom.
