Optional extensions
The basic unit is extendable with the following optional functions:
Leakage test
see also chapter 6.5.2.1 - "Entering set values" and chapter 6.5.1.1 - "Main
window "Process"", dialogue box "Operating mode: select/start" (7), button
"Standard unit test"
The leakage test enables the chamber of the freeze-dryer to be tested for
tightness in view of any gaseous or liquid media. Since absolutely tight
components simply do not exist, a leak rate is determined. The parameters
for the leakage test have been developed by Martin Christ Gefrier-
trocknungsanlagen specifically for freeze-dryers. In a first step, these
parameters (vacuum, ice condenser temperature) must be reached. It is not
until the conditions are fulfilled that the pressure control valve closes. Then,
the actual leakage test is performed in a second step. The leak rate that is
calculated after the end of the test provides information concerning the
tightness of the system.
USB process recorder
see also chapter 6.5.1.1 - "Main window "Process"", dialogue 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 be printed. It is also possible to
import the data directly into an Excel file.
LyoLogplus data logging software
LyoLogplus is a data logging software program by Martin Christ
Gefriertrocknungsanlagen GmbH that is specifically adapted to the
requirements of freeze-drying processes. Apart from the graphical
representation of the measurement data of currently running processes, it
also enables the data export for additional evaluation.
