    • A microtiter plate reader is disclosed which allows visual examination of the contents of the wells of a microtiter plate having an array of wells. The microtiter plate reader includes supporting means for supporting the microtiter plate with the wells opening generally upwardly and a light emitting surface is adapted to extend under a microtiter plate so held. Regions of reduced light emission on the light emitting surface are arranged in an array corresponding in relative position to a selected portion of the array of microtiter plate wells. Locator means are provided for locating the microtiter plate with respect to the array of regions of reduced light emission to allow selective alignment of the wells with the dark regions, providing a dark background to the bottom of the wells which are then illuminated indirectly. The wells can be illuminated directly when the dark regions are out of alignment with the wells.
    • 公开了一种微量滴定板读数器,其允许目视检查具有孔阵列的微量滴定板的孔的内容物。 微量滴定板读取器包括用于支撑微量滴定板的支撑装置,其中孔通常向上开口,并且发光表面适于在如此保持的微量滴定板下方延伸。 在发光表面上减少发光的区域以对应于微量滴定板孔阵列的选定部分的相对位置的阵列排列。 提供了定位装置,用于相对于减少发光的区域阵列来定位微量滴定板,以允许孔与暗区域的选择性对准,从而为井的底部间接提供了深色背景。 当暗区与井不对齐时,井可以直接照明。
