| Zusammenfassung: | To provide a dispenser which prevents air bubbles from popping out from a nozzle to enable highly accurate dispensing even if the nozzle is moved at high speed towards a liquid surface and then decelerated at high acceleration and stopped.SOLUTION: A dispenser provided herein is configured to start sucking a liquid 122 during a period from the time a nozzle 113 starts descending towards a surface of the liquid 122 in a sample container 100 to the time a tip of the nozzle 113 touches the surface of the liquid 122 and stops descending.SELECTED DRAWING: Figure 6
【課題】ノズルを液面に向かって高速移動させ、高い加速度で減速・停止させたとしても、ノズルから気泡が飛び出すことを防止し、精度の高い分注を実現可能な分注装置を提供する。【解決手段】分注装置は、ノズル１１３が試料容器１００内の液体１２２の液面に向けて下降し始めてから、ノズル１１３の端部が液体１２２の液面に接触した後かつノズル１１３が下降停止するまでの間の期間において、液体１２２の吸引を開始する。【選択図】図６ |
