Precautions when using in-situ freeze dryer
With the rapid development of modern technology, more and more freeze dryers have entered our work life, especially the in-situ freeze dryers have been favored by customers because of their excellent results. So what do you need to pay attention to when using the in-situ freeze dryer? Let's take a look at it together!
* Many heat sensitive substances will not be denatured or inactivated.
* When drying at low temperatures, some of the volatile components in the material are lost.
* During the lyophilization process, the growth of microorganisms and the action of enzymes cannot be carried out, so that the original traits can be maintained.
* Since it is dried in a frozen state, the volume is almost constant, and the original structure is maintained, and concentration does not occur.
* Since the moisture in the material exists in the form of ice crystals after pre-freezing, the inorganic salt-soluble substances originally dissolved in water are evenly distributed in the material. When sublimation, the dissolved substances dissolved in water are precipitated, which avoids the phenomenon that the inorganic salt carried by the internal moisture migration to the surface in the general drying method is precipitated on the surface to cause surface hardening.
* The dried material is porous and spongy. After adding water, it dissolves quickly and completely, and almost immediately restores its original character.
* Since drying is carried out under vacuum, there is very little oxygen, so some easily oxidizable substances are protected.
With the above comprehensive analysis, we have a more detailed understanding of the use of in-situ freeze dryers. If you have any questions in this regard, please contact us and we will serve you wholeheartedly.
