KingFisher Flex

KingFisher instruments automate extraction of DNA, RNA, protein, and cells by moving magnetic beads (not liquids), leading to clean extractions and enabling consistent results. Using a simple process (bind, wash, elute), KingFisher instruments can automate the extraction of any analyte of interest with a bead on it.

The Thermo Scientific™ KingFisher™ Flex Purification System provides highly versatile and reproducible products or MagMAX nucleic acid extraction kits, enabling users to process samples for a variety of purification of 24 or 96 samples per run. It can be used with a variety of reagents, including Dynabeads products or MagMAX nucleic acid extraction kits, enabling scientists to process samples for a variety of applications.
