Translation of the original operating manual
Option: USB process recording
see also chapter 6.7.1.1 - "Main window "Manual"", section "Dialog box
"Tools""
This feature enables the recording of a running process on a USB storage
medium. After the end of the process recording, the process data can be
viewed on the PC with LyoLogplus and they can be printed. It is also
possible to import the data directly into an Excel file.
Option: LyoBalance weighing system
see also chapter 6.7.1.1 - "Main window "Manual"", section "Dialog box
"Tools""
The LyoBalance weighing system enables the user to determine the weight
loss of a product during a freeze-drying process. The drying rate that
results from the weight loss provides information concerning the progress
of the freeze-drying process. Thereby, it also helps the user to determine
the end of the freeze-drying process and to optimise the process
parameters.
Special equipment: Aeration, stoppering, storage
see also chapter 6.7.3.1 - "Creating a program", button ">>more"
This option is available only in combination with the PGMplus programmer
module and if the freeze-dryer is equipped with an automatic aeration valve
and a hydraulic shelf movement system. It offers automatic sealing of the
product vials with pre-inserted rubber stoppers under partial vacuum and
subsequent storage on the shelves under defined conditions as an integral
part of a freeze-drying program.
Special equipment: Gas injection with a proportional valve
see also chapter 6.7.1.3 - "Main window "Options"", section "General"
If the freeze-dryer is equipped with a proportional gas injection valve, the
method that is to be used for vacuum control can be preselected. The
method can be saved together with a recipe.
Special equipment: Inertisation
see also chapter 6.7.1.3 - "Main window "Options"", section "General"
If products containing solvent are dried in an oxygen atmosphere, explosive
mixtures may form. In order to dry these types of products, the freeze-dryer
must be equipped with a door-controlled inertisation system that uses
nitrogen or another inert gas.
Special equipment: Preselection of the aeration medium
see also chapter 6.7.1.3 - "Main window "Options"", section "General"
If the freeze-dryer is equipped with an automatic aeration valve and
automatic valves for media selection, a special medium can be preselected
that is to be used for all of the aeration medium requests as of the start of
the main drying phase.
