  • Publication number: 20230160808
    Abstract: A microfluidic chip configuration wherein injection occurs in an upwards vertical direction, and fluid vessels are located below the chip in order to minimize particle settling before and at the analysis portion of the chip's channels. The input and fluid flow up through the bottom of the chip, in one aspect using a manifold, which avoids orthogonal re-orientation of fluid dynamics. The contents of the vial are located below the chip and pumped upwards and vertically directly into the first channel of the chip. A long channel extends from the bottom of the chip to near the top of the chip. Then the channel takes a short horizontal turn that nearly negates any influence of cell settling due to gravity and zero flow velocity at the walls. The fluid is pumped up to a horizontal analysis portion that is the highest channel/fluidic point in the chip and thus close to the top of the chip, which results in clearer imaging.

  • Publication number: 20220072541
    Abstract: Provided are devices for automated analysis of one or more samples in single or multi-well plates or vessels, wherein the process of automated analysis comprises automated flow, wherein the samples comprise liquid or particles in a sample vessel, and wherein the devices comprise an assembly of components that enable processing of a sample for analytical assessment by fluidic and/or particle based instruments. Automated flow may comprise systems for moving samples including vacuum systems, pressure-based systems, pneumatic systems, pumps, peristaltic pumps, diaphragms, or syringes. The devices may comprise an assembly of components that enable movement in X, Y, and Z dimensions, as well as switches, microfluidic tubing, well plate block, electronic pressure controllers, pneumatic or fluidic mixing devices, components for fluid handling, sampling vessels, and mechanical components for translating or transporting system components.
