    摘要: The sample vessel 1 comprises plurality of vessels 1a. The vessel 1a comprises an opening for sample inlet 3, a liquid sample outlet 4, and a silicon oxide composite particles structural body 2 is arranged at the bottom of the vessel 1a, i.e. the liquid sample outlet 4. The silicon oxide composite particles structural body 2 is a structural body composed of a composite made of plural silicon oxide particles having smaller diameter combined with a resin particle having larger diameter. Accordingly, even if the diameter of the silicon oxide particles 7 is set small in order to maintain the nucleic acid combination ability high, the presence of the resin particles 6 having a large diameter makes it possible to ensure the liquid conduction path, and the nucleic acid separating vessel, which is capable of suppressing decrease of the B/F separating velocity with maintaining the nucleic acid combining ability high can be realized.

    摘要: A centrifugal separator of the invention has a centrifugal rotor (10-1), with symmetric rotation axes, having single sample separation chamber in it for centrifuging samples contained in sample solutions, an upper opening passing through to said sample separation chamber in the upper part, members of frameworks capable of being coupled to said upper opening, a rotation driving means, assuming that the direction of said symmetric rotation axis is the first direction, for driving said centrifugal rotor around said rotation axis in the first direction, wherein assuming that two directions intersecting with said first direction are the second and third directions, the length of said sample preparation chamber in said third direction is longer than the length of said sample preparation chamber in said second direction. Since one kind of sample is handled in one centrifugal rotor, the centrifugal separator of the invention allows discrete treatment (sequential treatment) suitable for the flow system, in which individual samples can be treated independently, making easy automation of sample preparation revolving centrifugation.

    摘要: A thixotropic material is charged in a container. The container also holds a movable member which is placed in the thixotropic material so as to stir the thixotropic material. A force transmitting element is connected to the movable member. When an object, the vibration of which is to be controlled, is out of resonance, the amplitude of vibration is so small that the thixotropic material is in a gel state, thus presenting a comparatively large spring constant for the vibration control apparatus. As the excitation frequency is increased towards the resonance range, the amplitude of vibration is increased correspondingly, so that the movable member stirs the thixotropic material to generate stress in the latter, whereby the phase of the thixotropic material is changed from gel to sol. Consequently, the natural frequency of the vibration system, including the object and the vibration control apparatus, is lowered, thus averting resonance. It is thus possible to obtain vibration restraining or control effect over a wide range of excitation frequencies.
