Abstract
Disclosed are an improved stirring system and its operating method. The disclosed system includes at least two stirrers and a drive for driving the at least two stirrers to move between their stirring position and non-stirring position, the drive driving the stirrers to perform a stirring operation for a single purpose at a time. The system employs a single drive to drive a plurality of stirrers, which effectively avoids the disadvantage of redundantly stirring the reaction solutions in the reaction vessel not necessary to be stirred, reduces the risk of cross contamination caused by the stirrers and affecting the results by abnormal change in the absorbance, and makes the test results more accurate.
Claims22
A stirring system, comprising:
- at least two stirrers;
- and
- a drive for driving the at least two stirrers to move between a stirring position of one or more stirring positions and a non-stirring position of one or more non-stirring positions, and to drive the at least one stirrer of the at least two stirrers to perform a same stirring operation for a single purpose at a time, wherein
- the at least two stirrers are arranged on a same circumference and driven by the drive to rotate along a same circular track segment, and
- the stirring position is located on the same circular track segment.
A stirring system, comprising:
- at least two stirrers;
- a drive to drive the at least two stirrers to move between a stirring position and a non-stirring position, wherein
- the at least two stirrers are arranged on a same circumference and driven by the drive to rotate along a same circular track segment, and the stirring position of the at least two stirrers contains only one position on the same circular track segment.
A stirring system, comprising:
- at least two stirrers;
- at least one cleaning pool;
- and
- a drive for driving the at least two stirrers to move between a stirring position and a non-stirring position of the at least two stirrers, wherein
- a cleaning pool position of the at least one cleaning pool and the stirring position are equally spaced along a same circular track segment,
- the drive drives the at least two stirrers to rotate along the same circular track segment, and
- the at least two stirrers perform a same stirring operation for a single purpose at a time.
A stirring system, comprising:
- at least two stirrers that are both driven by a same drive mechanism, wherein
- the at least two stirrers are spaced apart such that fewer than all of the at least two stirrers perform a same stirring operation at a given time, and
- the at least two stirrers are driven by the same drive mechanism to rotate along a same circular track segment, and
- a stirring position for the same stirring operation is located on the same circular track segment.
A stirring system, comprising:
- a single drive mechanism;
- and
- at least two stirrers that are both driven by the single drive mechanism, wherein
- the at least two stirrers are spaced apart from each other such that fewer than all of the at least two stirrers perform a same stirring operation at a given time,
- the at least two stirrers are driven by the single drive mechanism to jointly rotate along at least two curved track segments to traverse between stirring positions and non-stirring positions, and
- the stirring positions and the non-stirring positions are located on the at least two curved track segments.
