Abstract: A prism used in analysis utilizing surface plasmons is prism of a dielectric medium with a predetermined reflective index. Trapezoidal prism comprises an incident surface on which excitation light is incident from outside, a reflective surface at which the excitation light incident on the incident surface is reflected, an emission surface from which the excitation light reflected by the reflective surface is emitted; and an opposite surface which opposes the reflective surface. The opposite surface is a recessed sink mark surface.

Abstract: A multi-core cable includes a plurality of electric wires, a jacket for covering the peripheries of the electric wires, and a strain relief to be mounted on the end of the jacket. The multi-core cable further includes a covering member to be fixed to the peripheries of the electric wires exposed from the jacket. The covering member is contacted with the strain relief to restrict the longitudinal-direction movement of the cable. Due to such characteristics of the multi-core cable, even when the cable is pulled, the connector attached to the cable tip end can be prevented against removal or breakage, thereby preventing the jacket against damage.

Abstract: According to this invention, a nucleic acid purification instrument whereby it is possible to prevent dispersion of a mist thai causes contamination upon discharge of a solution is realized. A pressurizing nozzle is allowed to come into contact with a nucleic acid capturing column such that the sealing member is compressed. An aspiration fan is operated and thus the air in a closed channel flows toward the bottom part of a liquid receiving tank and then toward the aspiration fan as a result of a partition board. The inside of the nucleic acid capturing column is pressurized using tho pressurizing nozzle such that a solution in the nucleic acid capturing column is discharged and gravity-fed to the lower part of a liquid receiving tank.
