Programming
The SPIN TISSUE PROCESSOR offers a wide range of
possibilities for programming processes of fixing and dehydrating
histological samples with reagents and then infiltrating them with
paraffin.
The control system enables up to 10 different processes to be
programmed (programs 01 to 10).
Before beginning to enter programs, it is a good idea to become
familiar with the cycle of the carrousel. Pay close attention to the
cycle performed by the basket at each of the 12 reagent vessels.
The figure below shows the movements of the basket and the
different phases that it goes through. The text describes these
movements and the times that can be adjusted.
•
Basket in the upper position or changing reagent
vessel.
‚
Basket in central position or centrifugation.
ƒ
Basket in lower position or immersion.
„
Downward movement. The basket does not turn.
…
Stirring by rotation for time T1 (programmable in
each reagent vessel). Reversal of the direction of
rotation each minute, with programmable rotation
speed (0, 60, 70 rpm) at each reagent vessel.
†
Only if
SHAKE
(vertical shake) is activated, at
each time T2 (set at 10 minutes), the basket with the
specimen holders shakes vertically when rising and
lowering.
‡
On completing time T1 for immersion, the basket is
centrifuged for programmable time T3. The direction of
rotation is reversed four times during the centrifugation
process.
ˆ
On completing the transfer stage, a new cycle
begins in the next reagent vessel.
T1 Time of immersion of the samples. The process
time for each reagent vessel (refer to Programming).
T3 Programmable centrifugation time. Eliminates any
excess reagent from the basket and avoids mixing the
products in the vessels.
• Level of the liquid in the reagent vessel (about
half).
