3 OPERATE WITH LOGOS ONE
LOGOS ONE is controlled by the Touch Control Terminal, which is a Windows CE 6.0 based.
It is a rapid TISSUE PROCESSOR for histology laboratories that guarantees high standard results. It can be
used in automatic or in dual mode depending on the laboratory demands.
The Resistance power output is automatically controlled by a PID (Proportional Integrative Derivative)
system, which allows the operator to set up the desired real parameters (Time and Temperature) by simply
drawing a curve. If a pre-stored program is used, it is only required to adjust the time of the procedure in
relation to the application specifications.
Thanks to the TIME at TEMPERATURE working procedures, LOGOS ONE allows consistency and
reproducibility of high quality results. The unit will always reproduce the same conditions of temperature in
the set times by automatically adjusting the Resistance power level.
LOGOS ONE has two cavities: a MAIN cavity and a WAX cavity. This feature allows user to run a process in
two different ways:
- AUTOMATIC mode: wax will be automatically pumped from the WAX cavity to the MAIN cavity for the
impregnation phase.
- DUAL mode: USER is required to MANUALLY move the RACK from the MAIN to the WAX CAVITY. A new
process can immediately be started in the MAIN CAVITY without waiting for the end of the impregnation
step. This allows for significant TIME SAVING.
The following section shows how to create, store, modify and run a program with the Touch Control
Terminal.
3.1 Loading cassettes into the rack
The Split Rack is made by 3 separate layers; each layer holds 70 cassettes for a total of 210 cassettes
(figure below).
Load the 3 layers of the SPLIT RACK CODE 66165A/210 with cassettes.
Each LAYER comes in a split design of two halves for simultaneous, convenient use in different grossing
rooms and embedding stations.
Each layer is provided with a locking mechanism (circles in figure below) to assure perfect closing of the two
halves.
Fully load each layer with cassettes, starting from the bottom layer first and avoid random
placement of cassettes over the three layers.
Start loading cassettes into a new layer only when the layer in use is full, thus avoiding a
possible “low reagent” situation in the cavity.
