In a method of detecting a test substance, a test substance is detected using a sample analysis cartridge supplied with a sample. The sample analysis cartridge includes: a passage part having a gas-phase space; and liquid containers communicating with the passage part through openings. The liquid containers include: a first liquid container containing a first liquid containing magnetic particles; and a second liquid container containing a second liquid containing a labeled substance. The magnetic particles are sequentially transported to the liquid containers through the gas-phase space in the passage part. Thus, the magnetic particles carry a complex of the test substance and the labeled substance. The test substance is detected based on the labeled substance in the complex.

A concentrating-enriching magnetic bead purifier includes a base, at least one first mixing sleeve socket, at least one second mixing sleeve socket, and a plurality of wells, and a controlling module. The first mixing sleeve socket includes a first magnetic rod, and a first magnetic rod sleeve. The second mixing sleeve socket includes a second magnetic rod and a second magnetic rod sleeve. A diameter of a cross section of the second magnetic rod sleeve is smaller than that of the first magnetic rod sleeve. The wells include at least one binding well, at least one washing well, and at least one elution well. The volume of the elution well is smaller than that of the binding well. The controlling module controls the first magnetic rod sleeve to only mix or adsorb in the binding well and the washing well and controls the second magnetic rod sleeve to mix or adsorb in the washing well and the elution well.

According to some aspects, a mixer for detection and/or removal of material in an undesired location of an additive fabrication device is provided. For instance, in an inverse stereolithography device, liquid photopolymer may adhere and cure or partially cure to a surface of the additive fabrication device in a location that may interfere with the additive fabrication process and/or cause the additive fabrication process to be unsuccessful. The mixer may be coupled to a movable structure within the additive fabrication device so that the mixer, when coupled to the movable structure, may be moved along at least one axis within the additive fabrication device. The mixer may be configured to detect and/or remove undesired material from a surface within the additive fabrication device.

Disclosed is a blood sample analyzer, including: a sample conveying device for conveying a sample rack loaded with a sample container; a first agitating device having a sample stirring component for stirring a blood sample in the sample container and being capable of driving the sample stirring component to uniformly agitate the blood sample in the sample container; a second agitating device capable of picking up the sample rack or a second sample container on the sample rack, and driving the second sample container containing a common-volume blood sample on a second agitating position to uniformly agitate the blood sample; and a controller configured to communicate with the sample conveying device, the first agitating device and the second agitating device, and control the sample conveying device, the first agitating device and the second agitating device. In addition, the present application further discloses a blood sample agitating device, a blood sample analysis method, and a computer storage medium.

Disclosed are systems and methods for a mixing device having a mixing chamber bounded by an inner surface of a wall, the wall having a cylindrical outer face and at least one feed duct which ends on one side with an opening in the cylindrical outer surface of the wall and on the other side with an opening in the inner surface of the wall. The mixing device also includes a magazine having a cylindrical inner surface, the cylinder axis of which is coaxial with a cylinder axis of the cylindrical outer surface of the wall, and a multiplicity of ducts. The magazine and wall are movable with respect to one another such that the openings of the multiplicity of ducts in the inner surface of the magazine are each connectable in a medium-conducting manner to the opening of the at least one feed duct in the outer surface of the wall.

A mixing device for bone cement comprising a plunger for extruding the mixed material, which plunger is also used as a cover. The plunger has spring blades adapted to be latched on a collar of the housing.

A device for mixing liquids and solids in liquids using vibration includes an electromagnetic drive, a drive shaft arranged coaxially with the electromagnetic drive, with drive shaft having a mixing member and either a permanent magnet or a magnetisable element excited by the electromagnetic drive to cause vibration for transmission to the mixing member, and a system of flat spring elements including a first spring element arranged parallel to the drive shaft and a second spring element arranged perpendicularly to the drive shaft and connected to the permanent magnet or the magnetisable element.

A bone cement applicator comprising a cartridge with an internal space. The cartridge has a head with a dispensing opening for expulsion of bone cement, a first thread, a dispensing plunger, a threaded tube having a counter thread engaging the first thread, a receptacle mobile in the threaded tube, and a mixing rod with a mixer fastened to it and arranged in the internal space of the cartridge. The mixing rod is detachably connected to the receptacle and is guided through a feedthrough in the dispensing plunger and is supported in the feedthrough so as to be axially mobile. When detached from the receptacle, the mixing rod can be pushed into the receptacle when the receptacle is propelled in the direction of the cartridge head. A method is also disclosed for production of a bone cement using the bone cement applicator.

A system and method for extracting essential oils from organic material is provided. One embodiment places organic material into an extraction chamber that is a cylindrical wall of rigid material, wherein a diameter and a height of the extraction chamber is sized to define an interior that accommodates a desired amount of an organic material having essential oils; fills the extraction chamber with a solvent after the organic matter has been placed into the extraction chamber; and moves a vortex plunger disposed over the surface of the organic material in a repeated upward and downward motion during an agitation process so that the vortex vanes generate a fluid vortex in the solvent, wherein the fluid vortex causes the solvent to be drawn upward into the organic material and then to be pushed downward through the organic material so that the solvent extracts essential oils from the organic material.
