A cartridge comprises a housing; a sample mixing compartment disposed within the housing, the sample mixing compartment comprising: an activation pouch, and a sample collection region; and a gas transporter tube having a first end and a second end, the tube being disposed within the housing adjacent to the sample mixing compartment, wherein the sample mixing compartment is partially defined by a moveable door of the housing, the moveable door providing access to the sample mixing compartment when the door is in an open position and preventing access to the sample mixing compartment when the door is in a closed position; and wherein the door is configured to release contents of the activation pouch upon movement from the open position to the closed position.

A specimen disrupting apparatus includes: a drive unit that rotates the lower portion of a container having a solution that includes a specimen, a great number of small diameter beads, and a large diameter bead stored therein; and a control unit that controls the drive unit. The control unit controls the drive unit such that the lower portion of the container rotates at two or more different rotational speeds which are changed continuously.

Auto sampler rack mounts and fluid vials that can be used with them are described. In some configurations, the rack mount can be configured to spin each fluid vial rotationally to assist in mixing or stirring of fluid in the vial and/or to maintain fluid homogeneity. If desired, the fluid vial may include one or more internal features to assist in the mixing or stirring.

It is an object of the present technology to provide a sample liquid accommodation container that has favorable dispersibility of microparticles in a sample liquid when the sample liquid is stirred and allows the sample liquid to be easily taken out.

The present technology provides a sample liquid accommodation container including: a container main body that has a bottomed cylindrical shape with an opening at one end and a bottom surface portion at another end, and accommodates a sample liquid containing microparticles; and a lid body that has a top surface portion and seals the opening of the container main body, in which the top surface portion of the lid body has a first through hole, and an inner surface of the top surface portion of the lid body has an inclined surface inclined upward with the first through hole as a highest point.

A device for agitating and collecting biological liquid samples comprises an agitator of racks of tubes, a sampling apparatus capable of collecting a biological liquid sample in a tube, and a changer capable of gripping a tube on a rack received in the agitator and moving it to the sampling apparatus. The agitator is capable of agitating at least three racks simultaneously, and the device also comprises a scheduler capable of determining destination data for a tube and destination data for the rack which receives this tube, and of determining for each tube a final location based on the destination data of the tube and the destination data of the racks received in the device, which final location designates a rack, received on the agitator and a position on this rack and can be different from the location of the tube when the rack that received it has been introduced into the device, and arranged to control the changer in order to grip a tube, present it to the sampling apparatus and replace it after sampling at the final location.

The present invention provides a cartridge, a detection method, and a detection device capable of stabilizing the liquid level of a sample accommodated in a chamber in a predetermined state. A cartridge 20, that is rotated around a rotating shaft 42 for detecting a target substance, is provided with a chamber 100 in which a sample containing a target substance is stored. The chamber 100 includes a first region 110 in which a sample is stored, a second region 120 disposed at a position closer to the rotating shaft 42 than the first region 110, and a protrusion 130 protruding from a position between the first region 110 and the second region 120 to the inner side of the chamber 100.

Methods and apparatus to mitigate bubble formation in a liquid are disclosed. An example apparatus disclosed herein includes a bottom wall, a first baffle cantilevered from the bottom wall, and a second baffle cantilevered from the bottom wall. The first baffle is spaced apart from the second baffle, and the first baffle and the second baffle are positioned radially relative to an axis of rotation of the apparatus.
