The present invention provides an electrophoresis device with improved abnormality detection capability. The electrophoresis device according to the present invention includes a flow passage with which a phoresis medium is filled, a first and second electrodes disposed at respectively a cathode side and an anode side of the flow passage, a power supply for applying voltage across the first and second electrodes, a pump for feeding the phoresis medium to the flow passage, and a control section. The control section executes operations including filling the flow passage with the phoresis medium, executing electrophoresis of a sample, and applying voltage to the first and second electrodes prior to the sample electrophoresis to determine a state of a current path based on a value of current flowing through the current path. The control section applies voltage to the current path for 20 seconds or longer in the determine step.

Electrophoresis device

The present invention aims to provide an electrophoresis device which detects the presence or absence of foreign matter in a flow path. In order to solve the above problems, the electrophoresis device of the present invention is characterized by including a flow pathfilled thereinside with a migration medium, a migration medium container which stores a migration medium, a liquid feeding mechanism which feeds the migration medium to the flow path, a photographing devicewhich photographs the flow path, and a control unit which analyzes an image of the flow pathphotographed by the photographing deviceand in that the control unit determines the presence or absence of the foreign matter in the flow pathon the basis of the image of the flow path

Provided is a capillary array unit configured to facilitate attaching/detaching operation. A capillary array unit includes a capillary, a load header provided at one end of the capillary, a capillary head provided at the other end of the capillary, a detection section provided at a portion of the capillary, and a holder holding the capillary. The holder includes a first holding section holding the capillary in a curved shape, a second holding section linearly holding the capillary, and a guide to move the second holding section in a predetermined direction.

With a microspectroscopy device provided with an objective lens with a high numerical aperture, a defocus arises from thermal drift, etc., necessitating auto-focusing. Conventional auto-focus based on through-focus image acquisition takes time, and thus, it cannot be applied to continuous measurement over a long time wherein high-speed sampling is carried out. The present invention addresses this problem by having a defocus-sensing beam that has either defocus or astigmatism fall incident on the objective lens. Since how the image of the spot of the beam for defocus sensing blurs differs depending on the orientation of the defocus, real-time detection of the amount and orientation of defocus becomes possible, and high-speed realtime auto-focus becomes possible.

Microspectroscopy device

Provided is a capillary electrophoresis device including a holder preventing a septum from coming off when a capillary is pulled out, and also allowing containers to be taken out in any order. In the capillary electrophoresis device for separating and analyzing a sample such as a DNA and a protein by electrophoresis, the holder includes: a septum having a capillary hole through which a capillary penetrates; a container for storing a solution; and a container-accommodation unit for accommodating the container. A hole formed in the septum engages with an engagement portion formed on the container, and thereby the septum is held to cover the container.
