Abstract A method for transferring a coverslip from one location to another comprises placing a suction pad on to one surface of the coverslip, applying suction to the suction pad so that the coverslip adheres temporarily to the suction pad and transferring the suction pad with the adhering coverslip from a first location to a second location. The invention also provides a specific apparatus for carrying out the method. Also provided is an apparatus for feeding coverslips singly from a stack of coverslips employing an open bottomed hopper for the stack of coverslips which rests on a plate having a depression, to accommodate a single coverslip, in its upper surface. The invention further provides a substantially automatic apparatus for placing mounting medium and coverslips on to microscope slides which apparatus can include the apparatus for transferring coverslips and the apparatus for feeding coverslips singly from a stack of coverslips.
In an apparatus for preparing specimen-containing slides for viewing under a microscope by placing a mounting medium over the specimen and a coverslip over the mounting medium, the improvement for transfering a coverslip from a first location to a second location comprising: A. a rigid supporting frame; B. a compressible bulb fixedly connected to said frame; C. flexible tubing connected to said bulb; D. a rigid pipe connected to said tubing; E. a suction pad connected to said pipe; F. reciprocating means to raise and lower said pipe and said suction pad in a linear path from a first position in contact with said coverslip to a second position in contact with said slide; and G. first compression means supported from said frame and adapted to compress said bulb just prior to contact of said suction pad with said coverslip, and to remove compression while said suction pad and said coverslip are engaged thereby retaining said coverslip in contact with said suction pad.
