Abstract: Aspects of the present disclosure include systems for dispensing a fluid, such as a sheath fluid, into a sample flow system of a flow cytometer. Systems according to certain embodiments include a housing and a pliant fluid dispensing container structure having a first pliant container and a second pliant container, where the second pliant container is configured to apply an amount of pressure to a fluid reservoir of the first pliant container sufficient to convey fluid from the fluid reservoir. Pliant fluid dispensing container structures and methods for using the subject systems to dispense a fluid, such as a sheath fluid to a sample flow system of a flow cytometer, are also described. Kits, having one or more of the pliant fluid dispensing container structures and sterile connector for coupling to a sample flow system are also provided.

Abstract: Systems for collecting light (e.g., in a flow stream) are described. Light collection systems according to embodiments include: a mount having an orifice for receiving light, an adapter configured for attaching a camera to the mount and a fastener for attaching a lens to the distal end of the mount and a releasably attachable connecter that is configured for coupling to an orifice plate and an aligner that is configured to couple with an aligner on the mount and maintain optical alignment between the mount and connector. Methods for coupling a connector and a mount are also described. Systems and methods for measuring light emitted by a sample (e.g., in a flow stream) are also provided.

Abstract: Aspects of the present disclosure include an optical detector scatter cap assembly. Optical detector scatter cap assemblies according to certain embodiments include a housing having a proximal end and a distal end, an orifice at the distal end of the housing, a scatter bar affixed to the housing and extending across the orifice and a cover bar that reversibly mates with the scatter bar. Also provided are systems that include the optical detector scatter cap assemblies, methods of using the systems, e.g., in sample processing, and kits that include component(s) of the optical detector scatter cap assemblies.
