Highly efficient and fast device designed for the extraction of nucleic acids with the magnetic method. Tailored to individual user needs, it enables simultaneous isolation of up to 96 samples, with the possibility of modifying the number of isolations to 64 or 32 simultaneously. Short extraction time up to 30 min. The system works on the basis of compatible isolation sets containing a set of reagents for conducting the process. The kit contains test plates with a specified purpose, lyophilizate with protease, and plastic, disposable covers for magnetic rods.
