SOLID-LIQUID SEPARATION METHOD AND DEVICE, PIPETTE TIP USED THEREIN, PARTICLE AND KIT

The present invention provides a solid-liquid separation method for a nozzle which does not require a complicated structure such as a filter, a solid-liquid separation device, and a pipette tip, a particle, and a kit used therein. Disclosed is the solid-liquid separation method including: sucking a suspension containing particles, through an opening formed at a leading end of a suction nozzle, into the suction nozzle; allowing at least a part of the particles contained in the sucked suspension, to sediment to be clogged in the suction nozzle; and ejecting a liquid inside the suction nozzle, through the opening of the suction nozzle clogged with the particles. 本发明提供无需有滤器等的复杂的结构的管嘴的固液分离方法、固液分离装置及在其中使用的移液器吸头、粒子及试剂盒。本发明从上述开口向在尖端形成开口的抽吸管嘴的内部抽吸含粒子的悬浮液，使抽吸的悬浮液中所含的粒子的至少部分沉降到至达到尖端开口的开口近前侧而在上述抽吸管嘴内阻塞，经尖端开口而排出内部的液体的固液分离方法。
