KingFisher Flex Purification is a versatile benchtop automated extraction instrument in the lab for 24 or 96 samples per run. It offers consistent medium- to high-throughput extraction and purification of DNA, RNA, proteins, and cells.

Designed to process up to 96 samples at a time, with volumes up to 5 ml, the versatile KingFisher Flex System has four interchangeable magnetic heads for various plate sizes, including 24- and 96-well well plates and PCR plates. Depending on the magnet head and plate, you can choose from a range of volumes (20-5000μL). The KingFisher Flex instrument can be integrated with liquid handling, robotics, and plate stacking instruments to automate your workflow for increased throughput fully.


Kingfisher Flex Purification Systems Overview

RNA extractions have significant applications in the present day. In terms of molecular biology, RNA extraction is the process of purifying RNA from biological samples. There are several methods to separate RNA from the given samples. One such method is the use of RNA machines, also known as purification machines. 

This extraction process and gene expression analysis have a lot of impact on the downstream applications. Apart from RNA, we also have methods for DNA extractions. The essential difference between these two methods is the pH value. For DNA extraction, the pH level is around 8, and it is around 5 for RNA. 

Recommended For:

  • Genomics and proteomics
  • Target identification
  • Veterinary assays
  • Biomarker discovery
  • Quality control
  • Forensics
