FREEZE DRYER CONTROL
THE LYOLAB 984 MICRO-CONTROLLER
21 CFR Part 11 Compliant
Upgrade your freeze dryer's control system
and improve product quality!
The Lyolab984 micro-controller was designed to
control and monitor the main lyophilization parameters on a
variety of machines. The Lyolab984 combines the functions of
separate temperature and pressure controllers together with
the cycle sequencer to integrate the automation of the lyophilization
cycle on a Windows 2000 ® PC. The Lyolab984 comes with a
moderate price tag and targets the retrofit market.
We believe that a control system must facilitate
the inter-relationship between the freeze dryer, the product,
the recipe and the operator. Therefore, a control design must
be evaluated in its ability to:
- minimize operator
error
- clearly define recipe
parameters
- provide a synoptic
of the machine for maintenance
- automate intervention
(AI) to alert possible malfunctions and product related behavior
deviations
- facilitate cycle
modifications before and during a cycle
- document a cycle
in both data log and graph modes
- support cGMP operation
- be user-friendly
The LyoLab984 Micro-controller
was designed with these functional characteristics in mind.

One of the most important functions of a fully
integrated control system is to simplify recipe definition.
With our unique EZ-n-Tree screens, recipe definition
is a breeze. Creating a cycle profile for lyophilization is
simplified by a series of prompting messages, help screens and
warnings. Once a recipe is outlined, the temperature profile
can be plotted, providing a visual representation
of the recipe prior to running a cycle.
Since readable and accessible
data is important in cycle development, the cycle batch
log can be printed in a variety of formats, including graphical
and numerical modes. Cycle data can also be imported into most
spreadsheets, databases, and can even be appended to a document
with a word processor. Our software is among the most flexible
on the market.
Lyolab 984 features include:
- Automated lyophilization cycle
- Automated performance cycle
- Manual synoptic mode
- Alarms and safeties annunciation
- Offline analysis of logs and graphs
- Password access security
- Multiple data presentation
(event log, graphic)
- Graphic recipe utility
- PLC-OMI Smart Link monitoring
- Recipe conversion utility
- Printing of logs/graphs in full color
- Simulation mode for training
- Easy to learn interface
At Lyotech we understand that a control
system is only as good as its supporting documentation. In the
cGMP environment of most pharmaceutical manufacturing, documentation
is critical for effective qualification
of the control system. The LyoLab984 Micro-controller, which
includes the PLC logic and OMI software, was designed for such
a cGMP environment. The PLC ladder logic and the OMI code are
fully documented including an operator interface manual, an
interface technical supplement, and electrical schematics. In
addition, a Control Qualification
(CQ) package is offered, providing
static I/O testing, safety interlock checks, sequencing checks
and software test scripts (black box testing), for complete
GMP readiness.
