Cold as Ice – gently dry
May 18th, 2016 | by Nils Münstermann
With Coolsafe Pro freeze drying, we can gently dry sensitive materials using an established process. The frozen water sublimates directly into the vapour phase. The process enables efficient, resource-saving drying, which increases the quality and shelf life of the materials. We use it to dry lignified starting materials, reaction products from aqueous syntheses or gels.
Tg, Tm, OMG – Understanding polymers
July 21st, 2014 | by Nils Münstermann
With every change in a system (e.g. phase transformation, chemical reactions), heat is either absorbed or released. This can be analysed quantitatively using differential scanning calorimetry. We can use a DSC 204 F1 Phoenix from Netzsch to measure cooling and heating processes from approx. -50 to 600 °C. The cooling and heating rates can be set from 0.1 to 100 K•min−1 .
