Abstract: 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.

Abstract: An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.

Abstract: A method of washing an aspiration probe of an in-vitro diagnostic system is disclosed. The aspiration probe comprises an outer surface and an inner surface forming an inner space for receiving a fluid. The method comprises dipping the aspiration probe into a first wash fluid so that the outer surface is immersed at least in part into the first wash fluid, aspirating an amount of the first wash fluid into the inner space of the aspiration probe, propagating an ultrasonic vibration to the outer surface of the aspiration probe via the first wash fluid, and rinsing the outer surface and the inner surface of the aspiration probe with a second wash fluid. Further, an in-vitro diagnostic method and an in-vitro diagnostic system are disclosed.

Abstract: An autosampler includes an injection port for supplying a sample to an analysis device, a needle that collects the sample stored in a vial and injects the sample into the injection port, a cleaning unit that cleans the needle and a gas exhaust fan. The cleaning unit includes a cleaning container which stores a cleaning liquid and into which the needle is inserted, and a unit main body that has a space for storing the cleaning container and receiving the cleaning liquid overflowing from the cleaning container, and a unit gas exhaust passage for exhausting gas in the space outwardly of the cleaning unit. The unit main body has a unit opening through which the needle passes when accessing the cleaning container. The autosampler includes a boundary portion that separates a first region in which the injection port, the needle and the unit opening are arranged from a second region in which the gas exhaust fan is arranged, and a gas exhaust region which is connected to the unit gas exhaust passage via a gas exhaust opening provided at the boundary portion and into which gas exhausted from the space flows due to a negative pressure generated by the gas exhaust fan.

Abstract: An automatic analyzer includes: a specimen holding unit configured to hold a specimen container in which a specimen is stored; a dispensed container holding unit configured to hold a plurality of dispensed containers; a dispensing probe configured to separate a predetermined amount of the specimen from the specimen container, and configured to dispense the specimen into the dispensed container; a probe washing device configured to wash a leading end of the dispensing probe in a washing liquid; and a controller configured to control driving of the dispensing probe. The controller includes an arithmetic processing unit configured to calculate a concentration of the specimen in the specimen container. The specimen is subject to dilution with the washing liquid adhered to the leading end of the dispensing probe in the probe washing device. The arithmetic processing unit sets a maximum number of times for dispensing the specimen, based on the concentration.
