Lyophilization Data Loggers
The lyophilization process is where
perishable food or material is
frozen and the water found in the
material is sublimated changing
from a solid sate to a gas state
without ever entering a liquid
The water vapor is then removed,
the material is lighter, more
stable, and can be stored easier.
Another term for the process is
freeze-drying, or cryodesiccation.
DATA LOGGERS To monitor and validate the temperature
data during the lyophilization process, the
user must have a logger that can record in
For most lyophilization applications, the
data logger being used should include a
temperature sensor or probe that is long,
thin and flexible for easy manipulation
and vial insertion.
AREAS OF STUDY
Lyophilization data loggers can provide
statistics for the experts in many fields,
Red cell freezing units
Priming biological pharmaceuticals
Data loggers dont have to be difficult to
use. Aim for a unit that is easy to operate
and small enough to not get in the way.
Units with alert indicators that signal the
status of the data will be helpful.
Other features that prove to be helpful are:
Recording in real-time
Delayed start times
Customized alarm notification
ACCESSORIES Below are two optional items that
will make the logging process easer:
A wall mount for your
lyophilization data logger.
Keep the unit within your
reach, visible and out of the
way at the same time!
A surface temperature probe
attachment. These are
created to measure the
surface temperature of any
tray or flat object and should
slide easily onto the end of
the loggers probe.
INTERFACE Transferring data from the
logger to a computer should
be a breeze.
USB cables, docking stations
and appropriate interface
software can make the
process a snap.
Always remember to go over
the manual with unfamiliar
CALIBRATION AND WARRANTIES
Another important factor is
the manufacturers warranty,
and if made available, the
Check this out to know what
is covered and what is not,
should something happen to
your data logger.
The harsh temperatures that a lyophilization data logger must record in can
cause its sensors to eventually become less precise and need recalibration.
Data loggers must be calibrated regularly to keep your recording values
When you first receive your product, look for the calibration certificate to
confirm the date of the calibration and make note of the date when the
next calibration is recommended.
IN SUMMATION When looking for a lyophilization data logger
remember to look for the following:
Ease of use
Size of device
Software to manage data and reporting

In 1992, Norman Carlson started MadgeTech
and his company has been a global provider
of data loggers ever since. MadgeTech is
located in New England and the company is
founded on innovation, consistency, and
