Microcon® Centrifugal Filters

Microcon® Centrifugal FiltersMicrocon® Centrifugal Filters simply and efficiently concentrate and desalt solutions of DNA, RNA, protein or other macromolecules, using any centrifuge that can accept 1.5 mL tubes. With the low- binding Ultracel® membrane, Microcon® filters offer:

  • Typical recoveries of >95%, even for dilute solutions
  • Reverse spin to maximize recovery, even in the smallest samples
  • Convenient storage of filtrate or concentrated sample in standard microfuge tube.

The Microcon® DNA Fast Flow Filter isis optimized for the concentration and recovery of genomic DNA. The low non-specific binding characteristics of the membrane and the other device components, coupled with its medical-grade o-ring seal, allows the device to accommodate several wash steps with minimal sample loss. With its inverted recovery spin, the device can concentrate samples up to 100X (for greatest consistency and reproducibility, we recommend concentration factors of < 20X).
