Abstract: Described herein are various embodiments directed to rotor devices, systems, and kits. Embodiments of rotors disclosed herein may be used to characterize one or more analytes of a fluid. An apparatus may include a first layer being substantially transparent. A second layer may be coupled to the first layer. The second layer may be substantially absorbent to infrared radiation. The second layer and the first layer may collectively define a set of wells. The first layer may define a base for each well of the set of wells. The second layer may define an opening for each well of the set of wells. At least one of the first layer and the second layer may define a sidewall for each well of the set of wells.

Abstract: Described herein are various embodiments directed to rotor devices, methods, and systems. Embodiments of rotors disclosed herein may be used to characterize one or more analytes of a fluid. A method may include bonding a first layer and a second layer using two-shot injection molding. The first layer coupled to the second layer may collectively define a set of wells. The first layer may be substantially transparent. The second layer may define a channel. The second layer may be substantially absorbent to infrared radiation. A third layer may be bonded to the second layer using infrared radiation. The third layer may define an opening configured to receive a fluid. The third layer may be substantially transparent. The channel may establish a fluid communication path between the opening and the set of wells.

Abstract: Described herein are various embodiments directed to rotor devices, systems, and kits. Embodiments of rotors disclosed herein may be used to characterize one or more analytes of a fluid. A method may include aligning an apparatus to an imaging device. The apparatus may include a set of wells defined by a first layer coupled to a second layer. The first layer may be substantially transparent to infrared radiation. The second layer may define a channel. The second layer may be substantially absorbent to the infrared radiation. The apparatus may further include a third layer coupled to the second layer and define an opening configured to receive a fluid. The third layer may be substantially transparent to the infrared radiation. A set of images of the apparatus may be generated using the imaging device. Bonding information may be generated based on the set of images.

Abstract: A centrifugal rotor device includes a first chamber configured to hold a fluid, and a second chamber configured to receive the fluid from the first chamber. The centrifugal rotor device also includes a conduit coupled to the first chamber at a conduit inlet and coupled to the second chamber at a conduit outlet, the conduit configured to permit movement of the fluid from the first chamber to the second chamber. The conduit includes a first channel and a second channel formed adjacent to the first channel. The second channel is in fluid communication with the first channel and has a dimension smaller than the smallest dimension of the first channel. The conduit also includes one or more obstructive features present in the second channel configured to impede movement of the fluid in the second channel.
