Abstract
An automated analyzer includes a rod-like member 12a, a driving portion 12c, and a control mechanism 30. The driving portion 12c lifts and lowers the rod-like member 12a a direction of being inserted into and removed from the container 24. The control mechanism 30 controls the driving portion 12c so that the rod-like member 12a is lifted after being lowered so that a tip portion of the rod-like member 12a reaches a first position in the liquid L, and at a time when the rod-like member 12a reaches a second position where the tip portion is not separated from the liquid, an upward motion of the rod-like member 12a is stopped for a given period of time to reduce liquid film adhering to the rod-like member.
Claims7
An automated analyzer comprising:
- a container for storing liquid,
- a rod-like member having a tip portion for being inserted into and removed from the container where a liquid is stored,
- a driving portion that lifts and lowers the rod-like member in a direction of the tip portion being inserted into and removed from the container, and
- a control mechanism for controlling the motion of lifting and lowering the rod-like member with respect to the container,
- wherein the control mechanism has a stored program that controls the driving portion so that the rod-like member is lifted after being lowered so that a tip portion of the rod-like member reaches a first position below the surface of the liquid, and at a time when the rod-like member reaches a second higher position but where the tip portion is not separated from the liquid, upward motion of the rod-like member is stopped for a stop time to permit the surface tension of the liquid to draw down liquid adhering to the surface of the rod-like member to reduce liquid film on the rod-like member, and then, after elapsing the given period of time, the rod-like member is lifted to a position where the tip portion is separated from the liquid.
A method for lifting and lowering a rod-like member in an automated analyzer, comprising:
- a first step of lowering a rod-like member, in a direction where a tip portion of the rod-like member makes contact with a liquid with respect to a container where the liquid is stored and so as to reach a first position in the liquid,
- a second step of lifting the rod-like member after completing the first step, and stopping an upward motion of the rod-like member for a stop time to permit the surface tension of the liquid to draw down liquid adhering to the surface of the rod-like member to reduce liquid film on the rod-like member, at a time when at least the rod-like member reaches a second position where the tip portion is not separated from the liquid, and
- a third step of lifting the rod-like member, after completing the second step, to a position where the tip portion is separated from the liquid.
