    4. OPERATION PROCEDURES Pre-freezing For the pre-freezing process, freeze samples quickly and completely through, at a temperature sufficiently lower than sample eutectic (solidification) point . Freeze as thinly as possible so that sample will not have a chance to melt before the drying process can dry it. Likewise, external heat may influence and begin melting samples with a low eutectic table, if it is frozen too thickly in the container.
