3.3 Functional Description of Components - System overview
A membrane keypad with 6 keys allows the user to set up the
processing parameters and also allows the user to start and stop
the processing runs.
An LCD display consisting of two rows, each row 16 characters
long, in which the progress of slide processing and the stainer's
processing parameters are displayed. The user is directed to take
various actions as necessary.
Figure 2 on page 10 shows an overview of the stainer.
The Leica ST4020 Linear Stainer has the following functional areas:
Keypad (14) with Display (13)
Slide carrier (1) and lift Bar (2)
Reagent container (4) and Rinsing Water Container (6)
The user inserts the slides for staining (3) in the slots of the slide
carrier (1). This is then placed onto the lift bar (2) , by which it is
transferred to the first reagent container.
The lift bar moves the slide carriers from one station to the next
station and eventually deposits them in the exit tank.
Each reagent container (4) can hold up to 50 ml of the reagent for
staining and processing.
A total of 14 reagent and rinse containers (6) can be arranged to
customize the stainer to carry out a specific staining protocol.
Each of the 14 processing positions must have either a reagent
container or a rinse container present.
