According to the invention, at least one of the first and second chambers of the static mixing nozzle contains a series of static backflow prevention elements, arranged for hindering backflow of the respective component within the respective chamber.

A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

Disclosed is a mixing chamber apparatus suitable for high-volume sampling (HVS) application. The mixing chamber apparatus includes, among other elements, inlet and outlet manifolds, a mixing chamber, and a tubing manifold for the introduction of clean, turbulent air into the mixing chamber. The inlet manifold defines a plurality of vapor ports that can be in fluid communication with one or more vapor sources to be sampled and mixed within the mixing chamber. Also described herein is a baffled mixing system that can be used alone or in combination with the disclosed mixing chamber apparatus.

The disclosure provides for a lab-on-a-chip (LOC) device and a method of fabrication thereof. Additionally, a system and a method for point of care testing of multiple biomarkers such as glucose, cholesterol, creatinine, uric acid, and bilirubin is provided. The microfluidic assembly consists of three layers in which the top and the middle layers are made up of polydimethylsiloxane (PDMS) and the bottom layer with polyethylene terephthalate (PET). The device integrates screen printed non-enzymatic electrochemical sensors in the bottom layer for simultaneous detection of glucose, cholesterol, creatinine, uric acid, and bilirubin. A hand held potentiostat with readout enables readout for the point of care application of integrated sensing device. The device developed has potential to revamp healthcare by providing access to affordable technology for better management a diabetes and related complications at every door step.

The present disclosure relates to a mixer device having a housing including at least first and second adjacent mixing cells (2, 3), each cell (2, 3) including a fluid inlet opening (21, 31) and a fluid outlet opening (22, 32), the inlet opening being offset from the outlet opening so that the axis of the inlet opening is parallel to the axis of the outlet opening, the outlet opening of the first cell being connected to the inlet opening of the second cell via a connecting channel.

A powder transfer bag includes a balloon or a membrane sealing its mouth. A connector to be used with the bags allows the bag to connect to a hydration device. A method of hydrating material in a powder transfer bag is provided.

The present invention relates to a fluid mixer having a fluid inlet (5), a first passage (1) which connects to the fluid inlet, a helical flow passage (2) which connects to the first flow passage, branched flow passages (4) which are branched from the helical flow passage, a second flow passage (3) to which the branched flow passages individually connect, a connection flow passage (7) which connects the first flow passage and the second flow passage, and a fluid outlet (6) which connects to the second flow passage. The branched flow passages are individually branched from different positions in the direction of flow through the helical flow passages. The branched flow passages which are branched from the helical flow passage individually connect to the second flow passage at different positions in the direction of flow through the second flow passage.

A spray assembly for dispensing a mixture is provided. The spray assembly includes a connector configured for operable engagement with a first and second source of component and a source of pressurized fluid, and a tip operably connected to the connector. The tip includes an opening and defines a mixing chamber between the connector and the opening of the tip, and an insert member configured to be received in the mixing chamber. The insert member includes a plurality of radially extending slots on at least one end of the insert. The plurality of radially extending slots is configured to mix the first and second components prior to the mixture exiting the opening in the tip.

A static mixer (M) for homogenizing a mixture of at least two liquids, especially after injection of an auxiliary liquid (L1) into a main liquid (L), includes: a closed container (1), with an inflow conduit (3) extending from a first wall of the container, up to the vicinity of the opposite wall, and an outflow conduit (4) which is substantially parallel to the inflow conduit, each conduit being provided with a device (3a, 4a) for connecting to the outside, through the wall of the container.
