    • A compressible and expandable sample tube holder includes a housing with a plurality of adjacent section members, movable toward and away from each other. Biasing members normally maintain the section members in an expanded condition. In the compressed condition the spacing between section members is reduced. A sample tube breakage detector includes slidable plungers having a protracted position that corresponds to a broken sample tube and a retracted position that corresponds to an unbroken sample tube in the sample tube holder. A detector compares the plunger positions before and after centrifuge spin to detect any broken sample tubes in the sample tube holder. A gripper device for the sample tube holder includes a lifting probe and a stabilizer to stabilize the sample tube holder during lifting. The gripper device and breakage detector are raised and lowered by a raising and lowering device having first and second telescoping members.
    • 可压缩和可膨胀的样品管保持器包括具有多个相邻部分构件的壳体,其可朝向和远离彼此移动。 偏置构件通常将截面构件保持在扩展状态。 在压缩状态下,部件之间的间距减小。 样品管断裂检测器包括可滑动的柱塞,其具有对应于断裂的样品管的延伸位置和对应于样品管保持器中的未断开的样品管的缩回位置。 检测器比较离心机旋转之前和之后的柱塞位置,以检测样品管支架中的任何破损的样品管。 用于样品管保持器的夹持装置包括提升探针和稳定器,以在提升期间稳定样品管保持器。 夹具装置和破损检测器通过具有第一和第二伸缩构件的升降装置升高和降低。

    • The read head for luminometer includes a housing that encloses a cylindrical core. The housing has a through opening that aligns with a central passageway of the cylindrical core to define a confinement space. The housing and the cylindrical core are formed in two parts that diverge or converge with respect to each other under the influence of a manually controlled actuator member. When the housing parts and the core parts are in a closed convergent position an analytical line that extends through the housing and the core is maintained in a confined position within the confinement space of the housing and the core. Actuation of the housing parts and the core parts into a diverged open position opens the confinement space that accommodates the analytical line. The analytical line can thus be lifted away from the previous confinement space or reinstalled back into the open confinement space and then locked in place by an actuation of the housing parts into a closed converged position along with the core parts. Installation or removal of the analytical line from the read head is thus accomplished in a direction that is perpendicular to the direction of the longitudinal axis of the confinement space.
    • 用于发光计的读取头包括封装圆筒形芯的外壳。 壳体具有与圆柱形芯的中心通道对准的通孔,以限定约束空间。 壳体和圆柱形芯部形成为在手动控制的致动器构件的影响下相对于彼此发散或会聚的两个部分。 当壳体部件和芯部件处于闭合的收敛位置时,延伸穿过壳体和芯体的分析线路保持在壳体和芯部的限制空间内的限制位置。 将壳体部件和核心部件驱动到分开的打开位置打开容纳分析线的约束空间。 因此,分析线可以被提升离开先前的限制空间,或者被重新安装回到开放的限制空间中,然后通过壳体部件的致动与芯部分一起闭合的收敛位置而被锁定就位。 因此,从读取头安装或移除分析线是在与限制空间的纵向轴线的方向垂直的方向上完成的。
