This automated analyzer 100 comprises: a sample probe 11a for dispensing a substance to be dispensed into a plurality of reaction vessels 2 for causing a sample to be analyzed to react with a reagent, a measurement unit (light source 4a, spectrophotometer 4, and control device 21) for measuring a reaction liquid produced from the sample and reagent in a reaction vessel 2, a cleaning tank for probe cleaning, and a control device 21 for controlling the operation of the probe, measurement unit, and cleaning tank 13. The cleaning tank 13 comprise a cleaning pool 36 for storing cleaning water for immersing and cleaning the probe and a drying tank 37 for sucking up the cleaning water on the surface of the probe after the probe has been immersed in the cleaning water of the cleaning water pool 36 and cleaned. As a result, it is possible to reduce the amount of cleaning water used to clean the probe.

This container storing a washing solution for a blood analyzer includes a container body made of thermoplastic resin resistant against a chlorine-based washing solution and provided with an opening on an upper portion, a chlorine-based washing solution stored in the container body, and a multilayer film covering the opening. The multilayer film includes a seal layer heat-sealed to the container body thereby blocking the opening and a gas barrier layer arranged on the outer side of the seal layer.

A method of cleaning an aspiration tube in a specimen measuring apparatus includes: moving the aspiration tube while discharging a cleaning liquid onto an outer side surface of the aspiration tube; stopping the aspiration tube in a state where a tip of the aspiration tube or a droplet attached to the tip contacts a surface of a flow of the cleaning liquid; and moving the stopped aspiration tube in a direction away from the surface of the flow of the cleaning liquid.

A dispenser device includes: a valve system, a dispensing head for dispensing liquid and connected with a transfer tube to the valve system, a dispensing pump connected to the valve system, a first inlet port for conducting rinse liquid to the valve system, and a second inlet port for conducting rinse gas to the valve system. The device includes control equipment for operating the valve system so that the flow via the transfer tube towards the dispensing head includes both the rinse liquid and the rinse gas. The rinse gas is capable of collecting gas bubbles formed on the inner walls of the transfer tube to larger amounts of gas. Thus, the rinse gas facilitates the removal of the gas bubbles with the aid of the rinse liquid.

Described herein are systems and methods used for washing needle assemblies with multiple needles.

A swab canister (101) is provided which includes a container (103) equipped with a first opening (105) and having a removable sample collector (117) disposed therein. A membrane (111) which is permeable to both moisture and a sanitizing agent such as ethylene oxide is disposed between the sample collector and the first opening. A desiccant (113) disposed between the membrane and the first opening.

A device and method for purification of information or particles from a sample and provides a device for performing washing steps in automated analyzer systems, the device comprising a multilayer unit with liquid channel and valves. The multilayer unit may comprise three layer.

A washing device comprises a fluid dispenser that operably directs a cleaning fluid to contact one or more objects to be cleaned, the one or more objects to be cleaned being contained by the washing device, a dispensing line directing the cleaning fluid to the fluid dispenser, a compressed air source, an air valve selectively controlling flow of air from the compressed air source into the dispensing line, a cleaning fluid source, a pump selectively pumping the cleaning fluid from the cleaning fluid source into the dispensing line, and a controller. The controller alternatingly activates (a) the pump to pump the cleaning fluid from the cleaning fluid source into the dispensing line and (b) the air valve to force the cleaning fluid from the dispensing line via the fluid dispenser.

Methods and apparatus to reduce biological carryover using induction heating are disclosed herein. An example method includes washing an aspiration and dispense device. The example method includes generating an alternating electromagnetic field and introducing the aspiration and dispense device into the alternating electromagnetic field. The example method includes inductively heating the aspiration and dispense device with the alternating electromagnetic field. In the example method, the washing is to occur in concert with the heating.

Cleaning fluids and methods for cleaning microfluidic channels are disclosed. The cleaning fluid includes surfactant coated magnetic particles, and the cleaning fluid may be guided into, through and out of the channels by using a magnetic field.
