    RECORDING with

    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

    ultra-low temperatures.

    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.


    Lyophilization data loggers can provide

    statistics for the experts in many fields,

    such as:

    Red cell freezing units

    Plasma observation

    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:

    Password security

    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



    Another important factor is

    the manufacturers warranty,

    and if made available, the

    extended warranty.

    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

    Included features

    Optional accessories

    Hardware interface

    Software to manage data and reporting
