In relation to an automated nucleic acid processor and an automated nucleic acid processing method using a multi function dispensing unit, processing involving extraction and amplification of the nucleic acid, can be consistently, quickly and efficiently conducted at a low cost with the use of a multi function dispensing unit, while saving user's trouble without expanding the scale of the device. The multi function dispensing unit includes: a nozzle head provided with a suction-discharge mechanism and nozzles detachably provided with dispensing tips; a container group having, at the very least housing parts for liquids and reaction containers for housing an amplification solution; a transfer mechanism that makes an interval between the nozzles and the container group relatively movable; a temperature controller whereby temperature control of the interior of the reaction vessels is possible; sealing liquids and/or sealing lids that are transportable to the reaction vessels using the nozzles, and which make the amplification solutions housed in the reaction vessels sealable within the reaction vessels; and a sealing control part that controls the suction-discharge mechanism or the transfer mechanism, such that the sealing liquid and/or the sealing lids seal the amplification solution within the reaction vessels when the housing of the amplification solution in the reaction vessels is completed.

A sample analyzer comprises a reagent container setting part configured to install a reagent-container retainer for retaining a reagent container having an opening, an aspirating tube configured to aspirate a reagent in the reagent container, and an aspirating tube holder configured to hold the aspirating tube. The aspirating tube holder includes a cover, the cover having an open portion provided from a bottom face thereof to a side face thereof, the cover covering the aspirating tube with a region thereof other than the open portion. The aspirating tube holder includes a guide portion configured to guide the aspirating tube holder relative to the reagent-container retainer such that the aspirating tube holder is allowed to reach a state where the aspirating tube has entered the reagent container or a state where the aspirating tube has retreated from the reagent container.

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.

There is provided an arrangement in a capillary driven microfluidic system for dissolving a reagent in a fluid. The arrangement (200) comprises a channel (102) for receiving a fluid at a first end, a valve (105) arranged at a second end of the channel so as to control a flow of the fluid to stop as it reaches the second end of the channel, and an actuator (108) for opening the valve (105) a predetermined time after receipt of the fluid by the channel (102). The arrangement further comprises one or more structures (106) for holding a dried reagent. The one or more structures (106) each has a width (W2) which is larger than a width (W1) of the channel (102), and the one or more structures are coupled to a side wall of the channel such that the fluid is allowed to enter the one or more structures from the channel, dissolve the dried reagent held therein, and diffuse back into the channel.

A disposable container for collection of microbe containing fluid samples is useful in a variety of microbial detection methods. One end of the container is provided with a lid comprising fluid flow apertures on one surface and a membrane filter (MF) on an opposed surface. Methods are disclosed wherein the container is disposed in a holding assembly with the lid gripped in a separate platform. The assembly and platform can be displaced relative to each other to separate the lid from the container.

A sample extraction chip and a biological reaction device are disclosed according to the present disclosure. The sample extraction chip includes a chip body and a sample extraction module provided on the chip body, the sample extraction module includes a sample-loading lysis unit, a liquid release-control unit, an extraction unit, a liquid switch-control unit, a liquid collection unit and a sample collection unit, which are connected through flow channels in a sequence of extraction. The liquid release-control unit is configured to store and release liquid reagents, and the liquid switch-control unit is configured to switch between communication of the liquid collection unit and the extraction unit and communication of the sample collection unit and the extraction unit. The sample collection unit includes a front collection portion and a rear collection portion which are both in communication with the liquid switch-control unit.

A multi-well fluid container that includes a container body is provided for use in an in vitro diagnostics automation system. The container body includes a first well having a first well size configured to hold a first fluid and an openable first well closure that covers a first well opening. The first well opening provides access to the first fluid in the first well when the openable first well closure is opened. The container body also includes a second well having a second well size configured to hold a second fluid and having an openable second well closure that covers a second well opening. The second well opening provides access to the second fluid in the second well when the openable second well closure is opened. The first well size of the first well is different than the second well size of the second well.

A receptacle for minimizing evaporation of a fluid includes a single-piece body, a fluid-tight seal, a penetrable septum, and a lid. The body includes a chamber having an opening. The fluid-tight seal is affixed to a surface of the body that defines the first opening. The fluid-tight seal covers the opening and is frangible. The septum covers the opening and the fluid-tight seal. The septum includes at least one slit forming slats. The lid has an opening axially aligned with the opening and is coupled to the body such that at least a portion of the septum is disposed between the lid and the fluid-tight seal.
