Dispensing Mechanism
Xylene is pumped from the xylene bottle by a pump
and then dispensed onto the slide. The xylene bottle is a
glass bottle (Figure 1-D) with a capacity of 500 ml. It is
located on the bottom left of the instrument and can be
accessed by opening the film door. The xylene dispense
volume is adjustable through the control panel with five
user-selectable levels: 1 (min), 2, 3, 4, 5 (max). When the
xylene bottle becomes empty, all of the slides held in the
coverslipping position will be coverslipped. The tube
length assures a sufficient volume of xylene to coverslip
20 slides. In order to fill the xylene bottle, it must be
removed from the instrument.
The waste bottle is a glass bottle with a 200 ml
capacity and is used to collect excessive xylene drained
from the dispensing area. The waste bottle is located to
the right of the xylene bottle. It must be removed from the
instrument to be emptied.
Coverslipping Stage
The first basket is automatically lifted from the loading
drawer to the coverslipping stage (Figure 1-E). Slides are
pushed one at a time from the loaded slide basket by an
ejector arm onto the staging area. A pre-set volume of
xylene is dispensed on the slide and then the film is cut to
the appropriate length and positioned on the slide.
Unloading Area
After the film is applied to the slide, it is returned to the
slide basket in the same position from which it was
removed. As each slide is coverslipped and returned to
the basket, the basket is moved up one position until all
slides have been coverslipped. The basket is then
transported upward to the unloading area (Figure 1-F).
The unloading area is located on the top of the instrument
and is protected by a cover. It contains a carousel-like
storage unit that can hold up to 12 baskets (240
coverslipped slides). The baskets can be removed
individually as they are placed into the unloading area or
can be held until all 12 positions are filled. The 12-position
unloading unit containing baskets can be removed from
the instrument.
