Abstract: Devices, systems, and methods related to a venting unit for a wall of a building structure are described herein. The venting unit may include a frame defining an airway, a filter arranged to filter air passing through the airway, a platen operable to cover the airway, and an actuator system coupled to the platen and the frame, the actuator system operable to angulate the platen at a first angle to preferentially direct air through the airway from a first direction and to angulate the platen at a second angle different than the first angle to preferentially direct air through the airway from a second direction.

Abstract: A measurement device containing one or more capillaries to measure the volume of a dispensed fluid and determine the volumetric accuracy of the dispensing device. The measurement device can contain a reservoir containing the fluid to be measured and there may be an additional reservoir for a secondary fluid. A viewing window is necessary to complete a manual measurement and may include a magnifying lens. The liquid well by the capillary inlet may be shaped such that the measurement fluid is directed toward the capillary. The well may have features designed to position the dispensing device toward the capillary, or to position the well proximal to the capillary after it is filled. The well may also have surfaces or coatings which attract or do not attract various types of substances. The measurement device may interface with sensors to output measurement data.

Abstract: This invention describes an advanced cooling system for a laboratory instrument to maintain laboratory samples at a predetermined temperature. The advanced cooling system uses an algorithm that incorporates information from at least one sensor and other operational parameters including thermal effects from the operation of the instrument.
