ExperimentFlashFreeze

ExperimentFlashFreeze[Objects]Protocol

generates a Protocol which can flash freeze Objects through immersion of sample containers in liquid nitrogen.

    
Flash freezing is the rapid freezing of a solution through exposure to cryogenic temperatures, resulting in the change of matter from the liquid phase to the solid phase. This is a done through direct submersion of the sample container into an open flask dewar of liquid nitrogen. This is often used to prepare biological samples for long-term storage (e.g. frozen cell line stock for tissue culture) or as an intermediate step during sample preparation for chemical reactions (e.g. freeze-pump-thaw degassing).
    

Experimental Principles

Instrumentation

    Figure 2.1: The flash freezing instrument consists of liquid nitrogen in an open dewar flask. Samples must be in a cryotolerant container that has a minimum temperature of at least -196 Celsius, and cannot be more than 50 mL in volume.

Example Calls

    FlashFreeze a sample

    FlashFreeze a sample:
    FlashFreeze multiple samples in the same protocol:
    Specify the freezing time for which the sample will be immersed in liquid nitrogen:

    Specify FreezeUntilFrozen

    If requested, a protocol will loop through the flash freezing protocol until a sample is completely frozen:
    If FreezeUntilFrozen is set, a protocol will loop through the flash freezing protocol until the sample is completely frozen. After the initial FreezingTime, a check will be performed on the sample. If the sample is not fully frozen yet, the experiment will freeze the sample again, up to a maximum of MaxFreezingTime, until the sample is deemed fully frozen:

Preferred Input Containers

    Samples can be flash frozen in containers that are cryotolerant and can safely be exposed to temperatures less than -195 Celsius. Due to safety concerns related to the possible condensation of atmospheric oxygen, flash freezing is limited to volumes less than 50 mL. Use the SamplePreparation option to prepare the samples if the samples are not in compatible vessels.

Possible Issues

    Sample container cracking/breaking during flash freezing.

    Given the extreme temperature of liquid nitrogen (boiling point -196 Celsius), if the container used for flash freezing samples is not cryotolerant, the container may break or crack upon immersion in liquid nitrogen. To ensure containers stay safely intact, consider using cryovials or similar tubes that have been specifically manufactured for stability under extreme cold.

    Incomplete freezing due to insufficient freezing times.

    Incomplete freezing may occur if the specified freezing time is not sufficient to allow for complete freezing of the sample volume. To avoid this, increase the allotted freezing time, or specify FreezeUntilFrozen to ensure that the sample is frozen all the way through.

    Not enough container space for the sample to freeze.

    Insufficient container volume relative to the sample volume may cause the container to break or the sample to expand out of the container while freezing, due to the fact that many samples, particularly aqueous solutions, expand upon freezing. To avoid this, aliquot the sample into a larger capacity container or split the sample into multiple aliquots to flash freeze.
