The control unit, after controlling the suction nozzle to sucks the solution in the well, controls the stage to rotate the stage on which the analytical unit is mounted at a predetermined speed of rotation, and controls the suction nozzle to suck a residue of the solution existing in the well.

Provided are methods and apparatuses for controlling a position of a target point on a processing result relative to a focus point of a focusing sensor system for determining properties of the processing result. The method includes the steps of determining an initial focus point of the focusing sensor system, controlling rotation of the cartridge and disc, checking whether the initial focus point of the focusing sensor system corresponds to the target point on the processing result, comparing (x, y) target positions in captured images with the initial focus point of the focusing sensor system, adjusting rotation of the cartridge and disc such that the focus point of the focusing sensor system corresponds to the target point on the processing result, and detecting and examining signals received from the focusing sensor system for determining properties of the processing result.

The present invention provides an automated system and method to isolate nucleated blood cells from whole blood or bone marrow. A disc mounted to a centrifuge system with spinning rotor is used to manipulate cells by channeling fluids while subjected to high gravitational field. The disc embodies at least two axisymmetric processing stations connected by a circular channel. Each station contains multiple chambers connected by fluidic channels to controllably transfer fluids. First stage separation allows for the isolation of the buffy coat layer while the second stage separation utilizes gradient density fluids to isolate the targeted nucleated cells from the buffy coat layer in the spinning disc.

The present invention also discloses a paper-based microfluidic device for detection of the progesterone metabolite for early determination of pregnancy in cattle and buffaloes. The invention further discloses antibodies developed against said metabolite, method of extraction, methods for fabricating the paper-based microfluidic devices and methods for inexpensive, rapid and non-invasive determination of pregnancy in early stages in cattle and buffaloes.

Magnetic beads having cell components of interest are translated between a sequence of processing wells in a tray without need for pipetting. The circular tray contains one or more sequences of wells each interconnected by a respective channel. The tray is rotated about a central axis and a magnet, an agitator, and a heater provided external to the tray enable magnetic bead translation, mixing, and incubation, respectively. The magnet proximate a well forms a cluster of beads. Manipulation of the tray in rotation and elevation results in translation of the cluster from one well, through a channel, and into an adjacent well. The well containing a cluster may be rotationally positioned in front of the agitator, the agitator extended into contact with the well, followed by mechanical agitation. The heater, disposed beneath the tray, may accept a well lowered thereto for selective heating.

A sample measuring method of optically measuring a sample housed in a container in a sample measurement device, the method including: loading the container such that the container is shielded from light; starting to read information regarding a measurement to be performed on the sample in response to the loading the container; and measuring the sample based on the read information.

A centrifugal reaction device includes: a centrifugal disk including a centrifugal shaft and at least one centrifugal holder, with the centrifugal holder disposed annularly about the centrifugal shaft; and at least one magnetic block disposed on at least one side of the centrifugal holder, wherein the centrifugal holder detachably holds a reaction tube, and the reaction tube contains magnetic beads, wherein the magnetic beads move within the reaction tube under a force of the sum of a magnetic force of the magnetic block and a centrifugal force. Therefore, a reaction mixture is blended quickly and sufficiently to facilitate a reaction. With the magnetic beads adsorbing a product, a valve of the reaction tube opens under the centrifugal force to discharge a waste liquid and reduce consumption of consumables of the reaction tube.

Provided herein are an optical test platform and corresponding method of manufacturing the same. The test platform may include a shell defining a cavity for receiving a sample tube, a first aperture, and a second aperture. The first aperture and the second aperture of the shell may each be configured to optically couple the cavity with an exterior of the shell. The test platform may further include a first window and a second window embedded in the shell. The first window may seal a first aperture and the second window may seal a second aperture. The first window and second window may each permit the optical coupling of the cavity with the exterior of the shell. The first window and the second window may be optically coupled via the cavity, and the shell may prohibit optical coupling between the first window and the second window through the shell.
