Platen The platen spans the entire front of the slide stainer, between the conveyor
spirals. The outside ridges of the platen are elevated guide rails, which
provide support to the glass slides as they are moved along the platen. The
functional areas of the platen are displayed in Figure 4-8.
The functions of the platen are as follows:
• Maintaining the exact volumes of the required fluids within a capillary
space between the platen and the glass slide.
• Providing a mixing system for the stain and buffer by way of two mixing
grooves.
• Providing the necessary time interval after the rinsing for proper drying
of the glass slides before they are deposited in the slide drawer.
A trough around the perimeter of the platen allows for drainage of used
fluids into the waste tank below.
Slide loading lines The slide loading lines are inscribed on the right side of the platen. They
indicate the correct placing of the glass slides in the conveyor spirals.
Conveyor spirals The conveyor spirals are two parallel spirals with opposing grooves. Glass
slides to be stained are fitted separately into the opposing grooves, which
move the glass slides across the platen.
Glass slides are moved by the conveyor spirals from right to left, first at the
vertical plane, then at the horizontal plane with the blood smear facing
downward toward the platen.
