Patent ID: 8889360

Claim:
An apparatus comprising: a biotip having: a chamber extending in a longitudinal direction axis and being charged with a liquid, the liquid being immiscible with a reaction mixture that has a larger specific gravity than the liquid; and a cap that seals the chamber; and a thermal cycler having: a holder to which the biotip is attached at a predetermined orientation, the holder including a first heating element for heating a first end of the biotip and a second heating element for heating a second end of the biotip; a rotating unit that rotates the holder; and a controller that has a first mode and a second mode, the first mode being a setting in which a rotation speed of the rotating unit is set to a first speed at which a magnitude of a centrifugal force that acts on the reaction mixture in the biotip arranged at the predetermined orientation by the rotation of the rotating unit is smaller than a magnitude of a gravitational force that acts on the reaction mixture in the biotip arranged at the predetermined orientation without being rotated, the second mode being a setting in which the rotation speed of the rotating unit is set to a second speed at which the magnitude of the centrifugal force that acts on the reaction mixture in the biotip arranged at the predetermined orientation by the rotation of the rotating unit is greater than the magnitude of the gravitational force that acts on the reaction mixture in the biotip arranged at the predetermined orientation without being rotated.
