Vessels for Cryo Storage of Sample Material

The preservation of valuable samples by cryo storage is becoming more and more standard in science and research as well as in medicine. In these areas, biological sample material is frozen at sometimes very low temperatures in order to maintain the vitality of whole cells or functional cell structures over a longer period of time. Sample vials made of the fluoropolymer PFA are particularly well suited for the storage and transport of sensitive samples. PFA is an ultra-pure, high-end polymer that is stable at temperatures as low as -200°C. These properties ensure the integrity and safety of valuable samples, which has led to a widespread use of these vessels in many laboratories.

Herstellung ultrareiner Säuren mit dem Subboiling-Säurereinigungsgerät APS-2000

Die Bundesanstalt für Materialforschung und -prüfung (BAM) in Berlin wurde von der AHF analysentechnik mit der Untersuchung beauftragt, inwieweit das Säurereinigungsgerät APS-2000 für die Aufreinigung von Säuren mit einer Subboiling-Destillation geeignet ist. Aus den Ergebnissen der Untersuchung ergibt sich, dass das APS-2000 in der Lage ist, Säure zu produzieren, die auch den höchsten Ansprüchen genügt und vergleichbar sauber ist wie die sehr teure kommerziell erhältliche ultrareine Säure.
