A well indicating device, for use with a microtiter plate that contains a plurality of substance-receiving wells, which comprises (i) a housing, having a top wall; (ii) an indicator display board, on the housing top wall, that contains light-emitting diodes for use in identifying individual wells in a transparent or translucent microtiter plate use in conjunction with the device; (iii) an alignment means on the housing top wall, for positioning the microtiter plate with respect to the light emitting diodes on the indicator display board, so that individual wells in the microtiter plate may be identified and illuminated via light transmitted from a light-emitting diode through the bottom of an individual well in the microtiter plate; (iv) a control means connected to or located in the housing, including a power switch adapted to be connected to an electric power source for energizing the device and an event swtich for operating the light-emitting diodes; and (v) an electronic circuit in the housing actuated by the event switch for operating the light-emitting diodes one at a time in a predetermined sequece, to individually identify each substance-receiving well of the microtiter plate which is the subject of manipulation.
