ABSTRACT:
Apparatus and method are disclosed for applying liquid to a series of individual, substantially flat objects. The apparatus and method are particularly adapted for staining microscope slides. The apparatus comprises a fixed plate member and preferably an opposing plate member positioned substantially parallel to and movable toward and away from the fixed plate member, aligned by means of at least one guide member which engages said plate members. A series of movable spacing shims extend along the guide member for separating flat objects, such as glass slides. The flat objects are inserted into the apparatus while the movable plate member is positioned away from the fixed plate member. Once the flat objects have been inserted in the apparatus between adjacent spacing shims the movable plate member is moved toward the fixed plate member to clamp the flat objects in predetermined spaced parallel face-to-face relation. At least one opening located in the fixed plate member allows liquid to flow over adjacent edge portions of the flat objects and fill the capillary gaps formed between adjacent flat objects by the spacing shims.
