Abstract: Fraction collector dispensers and methods of using such dispensers are provided. In one embodiment, the dispenser includes an inlet for receiving liquid from a liquid source, wherein the inlet is in fluid communication with an outlet from which liquid is dispensed into a receptacle; and a reservoir in fluid communication with a flow path between the inlet and outlet, wherein the reservoir comprises trapped air therein and is configured to receive liquid during movement of the dispenser between receptacles or during movement of receptacles between dispense positions, wherein the dispenser is moveable between a first receptacle and a second receptacle or the receptacles are moveable between dispense positions.

Abstract: Devices, systems, methods, and kits for contact imaging are provided. A contact imaging device includes an imaging sensor, a fixed fiber faceplate mechanically coupled to the imaging sensor, and an optical filtering layer mechanically coupled to the fixed fiber faceplate. The optical filtering layer can include an interference filter, an absorptive filter, and/or a removable fiber faceplate. The contact imaging device can be used to image fluorescent samples by filtering out excitation light on the basis of wavelength and/or angle of incidence.

Abstract: A combination imaging system includes a housing having a base and a lid, the lid having a closed position against the base and having an open position. The imaging device further includes a contact area image sensor. The lid shields the contact area image sensor from ambient light when the lid is in the closed position. The imaging device also includes a camera. The camera includes a lens, and the field of view of the camera encompasses at least a portion of an imaging area of the contact area image sensor when the lid is in the open position. The device may be especially useful for capturing a chemiluminescent image of an electrophoretic assay result, and capturing a colorimetric image of the same result, so that non-chemiluminescent protein standards may be located with respect to chemiluminescent analytes of interest.

Abstract: In one application, an imaging device includes an image sensor having an array of pixels, and a mask coupled with the image sensor. The mask is configured to darken a plurality of isolated pixels or groups of pixels interspersed within the array of pixels. The imaging device also includes a processor coupled with the image sensor and configured to receive image data from the image sensor, and determine a dark current fixed pattern noise based on the image data received from the plurality of darkened pixels or groups of pixels.

Abstract: A system for measuring an evanescent wave phenomenon at total internal reflection, the system comprising: a) a sensing surface comprising a plurality of areas of interest; b) an illumination sub-system comprising a light source, which illuminates each area of interest on the sensing surface over a range of angles of incidence; c) a detector which responds differently to an intensity of light received by it at different locations; and d) projection optics comprising primary optics and a plurality of secondary elements, the primary optics projecting an image of the illuminated sensing surface onto the secondary elements, which project their received light onto the detector in such a way that it is possible to determine, from the response of the detector, how much light is reflected from each area of interest, as a function of angle of incidence over the range of angles for that area.
