Monolayer device using filter techniques

A monolayering device for applying cells from a liquid suspension to a slide to be examined, comprising:

• measuring means for obtaining a quantity of the liquid suspension having therein a desired number of said cells;
• application vessel means located at a first station for receiving said quantity of liquid;
• a filter tape for receiving at said first station the liquid suspension from said application vessel means, said filter tape being capable of passing the liquid of the liquid suspension, while retaining said cells;
• vacuum means coupled to said application vessel means for sucking the liquid of the liquid suspension through said tape, thereby to deposit the cells on a tape portion of said filter tape;
• moving means for moving said tape portion having said cells from said first station to a second station;
• and biasing means for biasing said tape portion having the cells against the slide at said second station and thereby causing the cells to adhere to the slide.
