Microcon® Centrifugal Filters simply and efficiently concentrate and desalt solutions of any macromolecule, 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 •Concentration factors up to 100X The DNA Fast Flow Filter is optimized for the concentration and recovery of genomic DNA with SDS buffer. The low nonspecific 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. Features: •High recovery for small volumes with reverse spin (concentration factor <20X) •Low-binding Ultracel® membrane •Fast processing Sample applications: •Recovery of genomic DNA for forensic applications •Concentration and desalting of nucleic acids (high recovery alternative to ethanol precipitation) •Removal of primers from amplified DNA •Easy filtrate recovery, exploiting the flat membrane design Specifications: Maximum initial sample volume 0.5 ml Typical final concentration volume 5 -50 ?L OPTIMAL/maximum relative centrifugal force – Fixed angle rotor Microcon® 10K devices - 14,000 x g; Microcon® 30K devices - 14,000 x g Microcon® DNA Fast Flow - 500 x g 1,000 x g for recovery spin Active membrane area 0.32 cm2 Hold up volume ?10 ?L
