Diffinity Genomics has developed the fastest PCR cleanup product on the market today.      

Diffinity Genomics’ patented technology is a novel method designed to selectively remove dNTPs,              primers and primer-dimers from PCR-amplified fragments, while providing up to 90% recovery of high-quality DNA. This methodology allows simple, rapid, and inexpensive cleanup inside a pipette tip.  

RapidTips® are functionalized pipette tips that contain Diffinity resin. Using a simple, one-step protocol, Diffinity RapidTips cleanup PCR fragments in just one minute.

There are many technical publications that describe use of RapidTips for a variety of genomics applications.
