A pipettor includes a wash chamber between an upper plate, a lower plate, an upper seal, and a lower seal. The upper and lower seal retain each other and are located between the upper and lower plates. The pipettor includes a gasket located below the lower plate, a pipette tip retained by the gasket, and a piston with a tapered tip that passes through the plates, seals, and gasket into the pipette tip. The upper and lower seal isolate the piston from the wash chamber. The pipettor includes a channel defined by the piston, extending into the pipette tip, and an actuator that advances and retracts the piston. When the actuator retracts the piston such that the piston loses sealing contact with the lower seal and the wash chamber is supplied with wash fluid and pressurized, wash fluid passes through the groove in the upper seal and into the channel.

A controller associated with a machine may determine that a first subset of nozzles, of a plurality of nozzles of the machine, is to be cleaned. The controller may determine a first flow rate of the fluid through the first subset of nozzles and increase, based on determining that the first subset of nozzles is to be cleaned, the first flow rate of the fluid through the first subset of nozzles to a second flow rate of the fluid through the first subset of nozzles. The controller may decrease the second flow rate of the fluid through the first subset of nozzles to the first flow rate of the fluid through the first subset of nozzles when the first subset of nozzles is cleaned.

A method for cleaning an electrospray emitter of a mass spectrometer, comprises: (a) changing a mode of operation of the electrospray emitter from a stable jet mode of operation to a dripping mode or a pulsating mode of operation by lowering a magnitude of a voltage applied between an counter electrode and the electrospray emitter; (b) causing a cleaning solvent to flow through the electrospray emitter at least until a droplet of the cleaning solvent forms on an exterior surface of the electrospray emitter while operating the electrospray emitter in the dripping mode of operation; and (c) causing the droplet to dislodge from the electrospray emitter exterior.

An apparatus for the maintenance and operation of an air-cooled heat exchanger (ACHE) includes a plurality of spray tubes provided with spaced-apart nozzles permanently positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. The apparatus is operable in several modes, including cleaning where the flow of air is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When extremes of ambient air temperatures preclude the forced air fans from achieving the target temperature range of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles, or alternatively, pressurized heated air is discharged from the nozzles.

Provided is a fluid treatment system, including: a plurality of fluid channel devices arranged in series along a regular channel; a plurality of flow control valves each adjusting the flow rate of a treatment target fluid flowing into each of the plurality of fluid channel devices; a flow control valve provided on the upstream side of the plurality of fluid channel device and operable to change the flow rate of the treatment target fluid flowing into each of the plurality of fluid channel device; a bypass channel allowing the treatment target fluid to flow so as to bypass the fluid channel device in which abnormality has occurred, and a plurality of bypass selector valves selectable between a state of allowing the flow of the treatment target fluid in the bypass channel and a state of blocking the flow.

A system for cleaning filter cartridges having a cylindrically configured filter media. The cleaning system includes a tank for containing a cleaning liquid, and an open-sided cage for removably receiving and containing one of the filter cartridges to be cleaned. The cage is supported on a drive shaft of a motorized drive that is positionable for disposing the open-sided cage and filter cartridge contained therein in cleaning liquid in the tank and is selectively operable for rotating the open-sided cage and filter cartridge contained therein during a cleaning cycle for cleaning the filter media of the contained filter cartridge.
