Rotational speed of a spray arm is regulated based on centrifugal force and a liquid jet to create a variable angle corner spray nozzle. The regulator includes a weight on a pivot and a fluid jet, the weight having a curved surface to produce a variable angle corner spray nozzle depending on the weight angle. Centrifugal force created during rotation pushes the weight outward, which increases as the spray arm rotation speed increases. The liquid jet is located out from a pivot point and tends to push the weight inward. The pushing force of the liquid jet is maximum when the weight is most inward and minimum when the weight is most outward. The regulator stabilizes the arm speed at a specific speed independent from center pivot friction and the spray arm nozzle's orientation tolerance. Speed stabilizes when centrifugal force on the weight is equal to the pushing force of the fluid jet.

A method for cleaning a vaporizer that vaporizes, at normal temperature and pressure, a source material in a liquid state, and supplies the vaporized source material to a reactor through a supply pipe, includes a cleaning step of passing the source material to the vaporizer while maintaining the source material in a liquid state to clean the vaporizer.

The present application is directed to a sampling system for sampling a fluid from a vessel, where the sampling system includes a sterile dispenser assembly operatively connected to the vessel, the sterile dispenser assembly including a valve operatively connected to the vessel, a membrane, and a needle, and a detachable sterile sampling container assembly operatively connected to the sterile dispenser assembly, the detachable sterile sampling container assembly including a sampling container, a membrane attached to the sampling container, and a sampling container housing enclosing the sampling container, where the sampling container housing includes a compressible portion having a deflated configuration and an expanded configuration.

A bypass flow monitoring chamber that may be retrofit onto the main chamber of an incubation chamber, for continuous collection of environmental samples. This allows for the measurement and correction of the environmental conditions within the chamber, and the return of the sample to the main chamber. Utilizing this sampling method, the separable bypass flow monitoring chamber may be isolated from the main chamber by a set of valves during a period of high-heat decontamination of the incubator therein protecting the sensors and contents of this separable chamber, as well as allowing the use of less expensive and lower temperature rated incubator sensors.

Since a detergent is a consumption article, it is desirable that a use amount of the detergent be as small as possible in a limit that the washing effect is not substantially reduced. Provided is an automatic analyzer which includes a syringe pump which is connected to a probe and performs the body aspiration and discharge, a feed pump which feeds washing water for washing the inside of the probe to the probe via the syringe pump and a controller which controls the dispensing mechanism and the syringe pump, in which the controller, in a case of washing the probe by sucking a detergent in the probe a plurality of times, controls the syringe pump so as to discharge the detergent after sucking the detergent and to suck the next detergent without feeding the washing water to the probe by the feed pump.

A system for conducting urinalysis of urine is provided. The system includes a housing mountable on a urination device defining urination area; a dispenser mounted in the housing and being configured for holding a plurality of urine test strips (hereinafter “UTS”). Each one of the UTS includes at least one reacting area configured for a chemical reaction with a substance in the urine. The system further includes a detector configured for detecting at least one property of the reacting area and a shifting mechanism configured for extracting one UTS from the dispenser and moving the UTS to a urination position in which the UTS is disposed above the urination area, such that the reacting area is disposed along a urine path.

A solvent compound for a particle counter/imager system, the solvent compound includes a liquid solvent miscible with oil to remove oil from the particle counter/imager system and a liquid dispersive surfactant configured to break large water droplets into smaller droplets less than a predetermined size. The liquid dispersive surfactant is miscible with the solvent and is nontoxic and nonflammable.

Disclosed herein are cell processing systems, devices, and methods thereof.
